List of Mattress Brands that Do NOT Use Fiberglass

Last Updated on February 23, 2024 may earn commissions from Amazon and other affiliates through links in this article.

Below is a big list of fiberglass free mattress brands that can be found online. These are mattress brands that have been scrutinized from top to bottom, ensuring safety and good sleep that’s healthy and full of rest.

Stack of Mattresses with text that says Big List of Mattress Brands that don't Fiberglass

I contacted all of these “Bed-in-a-Box” mattress brands on the web to ask this question:

Do any of your latex and/or memory foam mattresses contain Fiberglass?

Then I fact-checked everything the mattress maker said while checking its websites’ darkest corners, product reviews on Amazon/Walmart, Youtube videos, and Reddit to find the best mattress brands without fiberglass.

Unlike other lists of 200+ fiberglass mattresses, I do NOT just take what a mattress maker says as truth. Silica isn’t always just silica, and core-spun glass fiber is just another form of fiberglass. Plus, many mattress brands are deceptive and outright lie about fiberglass use in the mattresses they sell.

Mattress Brands to Be Wary of when Buying

  • BedStory
    BedStory makes some of the most affordable mattresses while claiming they are made without fiberglass, both hybrid and memory foam. In an email BedStory stated it uses flame retardant viscose (FR rayon) and low melt point PET fibers (polyester), but this has not been confirmed.

    CHITA sells more than one mattress without fiberglass on Amazon. However, CHITA isn’t very open about the other materials used in its mattresses.

    IULULU mattress listings claim to be fiberglass free on Amazon, but when I contacted IULULU it could not provide any information regarding what flame retardant is used instead.

  • Keetsa
    KEETSA makes innerspring, hybrid, and memory foam mattresses with no fiberglass in the materials. However, KEETSA does use some questionable chemicals as a fire retardant in its mattresses – Polyethylene Glycol, Glycerin, and Phosphate Salts – Chemicals that don’t have much available information on their viability as a healthy flame-resistant alternative.

    MLILY mattresses are made without using fiberglass. Instead of Fiberglass, MLILY uses Amidinourea Phosphate and Ammonium Polyphosphate as a flame retardant.

  • Molblly
    Molblly mattresses are fiberglass free, but previously ALL of its mattresses contained fiberglass when initially questioned. Molblly’s new flame barriers design is 92% cotton and 8% polyester, which means there is some sort of flame-resistant chemical treatment. I recommend being careful when buying a Molblly mattress since there could be old mattresses still around that contain fiberglass.

  • Nolah
    Nolah’s “Natural” mattress in a box has no fiberglass and is made with organic latex and organic wool. The Nolah Nurture line is also fiberglass-free. However, Nolah’s other lines of mattresses contain a “woven silica” firesock that’s supposedly made of hydrated silica.

  • Novilla
    Novilla used to make mattresses that contained fiberglass, but some time during 2022 Novilla mattresses became fiberglass-free. However, Novilla has yet to disclose what exactly they have replaced fiberglass with in order to pass flammability testing regulations.

  • Silk & Snow
    Silk & Snow mattresses are made without fiberglass in Canada. However, United States customers should be aware that all Silk & Snow do contain fiberglass EXCEPT for the Organic mattress that uses wool instead.

  • SweetNight
    Sweetnight used to add fiberglass directly into the foams used in its mattresses during manufacturing, which allows it to say its mattress covers were fiberglass-free. However, some time during 2023 SweetNight supposedly stopped using fiberglass, but it’s not been confirmed nor does the company state what flame retardant is being used instead.

  • Tuft & Needle
    Tuft & Needle used to put fiberglass in all its lines of mattresses, but it started making mattresses without fiberglass instead. However, you never know if you’re getting an old mattress from a warehouse that has fiberglass. Also, at one point Tuft & Needle put its name on some economy fiberglass mattresses being sold at Sam’s Club.

Fiberglass Mattress Brands to Avoid

  • Best Price Mattress
    Best Price Mattress states its foam mattresses only contain silica. Amazon review photos of Best Price Mattress tags show they do contain fiberglass. Best Price Mattress’ website states mattresses are Designed in the USA but fails to mention that they could actually be constructed in Canada, Europe, or USA. I would look at other options.

  • Casper
    Casper uses fiberglass in its mattresses, along with modacrylic, polyester, and rayon. Casper avoids the truth by saying it’s just silica, but with careful questioning the truth can be coaxed out. Perhaps the most concerning issue is Casper’s support insisting its mattresses would only leak silica that has come apart from the fiberglass, not the fiberglass itself.

  • Classic Brands
    Classic Brands uses fiberglass in mattresses as a fire retardant. They ignore questions regarding where mattresses are manufactured, but the Classic Brands FAQ page says China or USA depending on the mattress.

  • Dormeo
    Dormeo claims to be fiberglass free in its live chat, but its website doesn’t say anything about being fiberglass-free or what’s used instead of fiberglass. Also, a user on Twitter/X had the inner cover of her Dormeo mattress tested by a lab and it came back as vitreous fiber, which is anther term for glass fiber.

  • Emma Sleep
    Emma Sleep makes mattresses that use 60% modacrylic and 40% Silica as a fire retardant, and I strongly suspect the “silica” is just fiberglass.

  • Ghostbed
    Ghostbed uses what it calls a “glass fiber scrim” inside its mattresses for flammability testing, it just sounds like a regular fiberglass firesock.

  • Inofia
    Every time I contacted Inofia about fiberglass, my question was ignored and I was instead given information that I didn’t request. Rather than get stuck in a never-ending loop of asking the same question over and over I decided that Inofia probably contains fiberglass.

    LEESA uses fiberglass in its mattresses, it’s a core-spun fiberglass thread found in the firesock that’s just beneath the outer cover of the mattress.

  • Linenspa
    Linenspa’s 5″ Gel mattresses contain fiberglass, while the rest of its mattresses use a fire-retardant treated cotton that should probably be avoided.

    All of LUCID’s mattresses contain fiberglass, except its gel-infused line of mattresses which contain fire-retardant treated cotton instead.

  • Milton Sleep Co.
    Milton Sleep Co completely dodged fiberglass questioning and said that anyone avoiding synthetic materials should just avoid Milton Sleep Co mattresses.

  • Nectar
    Nectar admits the use of Fiberglass in its mattresses, as well as Rayon and Polyester. Nectar initially denied the use of any potentially harmful material in its mattresses when contacted but changed its answer when shown Amazon reviews of Nectar mattresses leaking glass-like particles. Nectar should be avoided at all costs.

  • Olee Sleep
    Olee Sleep openly states its mattresses are made with fiberglass along with Polyester, Acrylic, and Spandex.

  • Perfect Cloud
    Perfect Cloud uses fiberglass in its mattresses, but claims the fiberglass is “Special”. Common sense says it’s probably not.

  • Puffy
    Puffy used to avoid material questioning and just said its firesocks were silica and wool encased in polyester. However, there is a Puffy FAQ page that confirms fiberglass in its mattresses.

  • Purple
    Purple says it uses silica spun into a yarn that’s knit into the fabric of the mattress flame barriers. However, That’s exactly how fiberglass is used in mattresses. Plus, even if it’s not fiberglass, pure silica fibers could lead to the same problems as fiberglass fibers.

    SEALY initially dodged questions and just said its mattresses are made in the United States. However, Sealy eventually admitted its use of core-spun fiberglass after much questioning.

  • Signature Designs (by Ashley)
    Ashley Furniture avoided Signature Designs fiberglass questioning, but numerous reports of fiberglass leaking from mattresses in Amazon reviews and on Reddit pretty much confirmed the strong suspicions that it uses fiberglass in its mattresses.

  • Signature Sleep
    Signature Sleep’s firesocks are 50% fiberglass and 50% Modacrylic. Signature Sleep is pretty honest about this fact, which is more honorable than some of the other bedmakers.

  • Sleep Number
    The first Sleep Number associate I spoke with when I called said she was pretty sure all Sleep Number mattresses have fiberglass. However, after transferring me to different departments for confirmation, the question of fiberglass was danced around and avoided like the black plague. That is a pretty good reason to avoid Sleep Number.

  • Sleepy’s (by Mattress Firm)
    While in contact with Mattress Firm I was told that Sleepy’s mattresses are made the same way as the Tulo brand. This means Sleepy’s mattresses are made with fiberglass as the flame retardant.

  • Stearns & Foster
    I was told by Stearns & Foster that it uses core-spun glass fiber in its flame barrier. This is the same cores-spun fiberglass that sister companies Sealy and TempurPedic use in their mattresses.

  • Tempur-Pedic
    Tempur Sealy’s Tempur-Pedic mattresses definitely contain fiberglass. Although Tempur Sealy tries to avoid disclosing materials used in its mattresses, after careful questioning they admitted the use of core-spun fiberglass in Tempur-Pedic mattresses.

  • Tulo
    I asked Mattress Firm via chat about fiberglass in Tulo mattresses, and they gave me a straight answer. Tulo mattresses by Mattress Firm do in fact contain fiberglass, the flame-retardant firesock contains fiberglass. The tags on Tulo mattresses don’t list fiberglass as a material, and Mattress Firm was pretty dodgy about fiberglass questions until very recently.

  • Zinus
    Zinus was the first big brand to be involved in class-action lawsuits regarding fiberglass back in 2020. Even so, Zinus still uses fiberglass in its mattresses in spite of that.

Why Make a List of Mattress Brands Without Fiberglass?

In late 2019 I published one of the first articles about fiberglass in mattresses that gained substantial attention online, it was shared on Reddit, Tumblr, social media, and even some fiberglass awareness websites. Since then, fiberglass being used in the mattress industry has gained a lot more attention on social media, TikTok, and even in the news.

Unfortunately, my article was also noticed by big mattress review websites. The big mattress review websites copied and re-wrote my article to be used as a marketing strategy for selling mattresses. They used their fiberglass mattress articles just to make money instead of being a resource to help people be safe and healthy. Some of the mattresses they recommended at times weren’t even fiberglass-free.

While the article is still on this website, its title and address have changed to keep up with the times, and the big table was removed because it didn’t work well on mobile devices. Also, the content has evolved due to the changing nature of the internet and the constant battle against these mattress websites and their teams of writers and SEO specialists over Google search engine rankings.

Basically, this List of Mattress Brands Without Fiberglass is information that no longer fit or worked in other fiberglass-free article at Rather than just scrap the list of mattress brands without fiberglass and replies from mattress brands about fiberglass, I decided to give it a new home.

What Mattress Brands Without Fiberglass Say vs. Brands With Fiberglass

These are the actual replies from mattress brands about fiberglass when I reached out to them through email or chat. Not only do I ask about dangerous fiberglass, but also FR Sprays and Silica, as well as Rayon and Polyester since some people are sensitive to those materials.

The replies take up a lot of space on the page so I’ve hidden them behind a spoiler.


AmazonBasics mattresses are made by various manufacturers, so it would be hard to track down who made what, and even If I did, it could change at any time. I would just play it safe and look elsewhere when seeking a bed without fiberglass.


Amerisleep’s response:
“Not only does the foam in Amerisleep mattresses meet the Certi-PUR® standards, but we also use plant-based materials instead of petroleum to make our foam. On top of that, our patented manufacturing process is the only one that meets the standards of the Clean Air Act. To clarify, our memory foam mattresses do not contain fiberglass, modacrylic, or silica in our covers. In addition, our mattresses are manufactured in the U.S.!”

I questioned Amerisleep a bit more later and was given a PDF for its firesock material. It’s called “PyroGuard FR Barrier Fabric” made by Cyberknit and it’s a Cotton and Polyester blend manufactured without the use of glass, silica-loaded rayon, modacrylic, melamine, antimony, phosphorous, or chlorine.

Amore Beds

Amore Bed’s response:
“The only thing that we are aware of is that our Bamboo copper fabric is Rayon. To play it on the safe side, we would recommend our Natural Hybrids.”

Amore Beds makes fiberglass-free mattresses that are free of harmful chemicals. The copper infused mattress covers by Amore Beds use a copper-infused rayon, but its Natural mattress cover option is organic cotton.


BedStory’s response:
“The mattress fireproof layer is made of flame retardant viscose and low melt point PET fibers according to CFR1633 standard, totally no fiberglass. The mattresses are manufactured in the United States, China or Cambodia.”

BedStory makes mattresses without the use of fiberglass, but they do use Rayon and Polyester. That’s not bad!

Best Price Mattress

Best Price Mattress’ response:
“Our memory foam mattresses contain a silica based fire sock that encases the foam inside the mattress. Our materials are globally sourced in countries such as Thailand, Spain, Serbia, Vietnam, China and South Korea.”

A bit shady – Best Price Mattress dodged the fiberglass question and stated its foam mattresses only contain silica when I contacted them, however, Amazon reviews prove Best Price Mattress contains fiberglass. Also, the Best Price Mattress website says mattresses are “Designed in the USA” but fails to mention that they could actually be constructed in Canada, Europe, or USA.

Brentwood Home

Brentwood Home’s response:
“Our memory foam mattresses are made right here in our factory in Fullerton, CA. They do not contain fiberglass in any part of the mattress and we use hydrated silica as a fire barrier. I have reached out to our product specialist team about modacrylic and as soon as I hear back I will get back to you.”

The response from Brentwood is pretty favorable, since it doesn’t use fiberglass, and hydrated silica is generally regarded as safe. I’m still waiting to hear back about Modacrylic and the use of Fire Retardant sprays. However, upon closer inspection of their website’s comparison page I can see that one line of mattresses contains a cotton/polyester blend, another uses a wool/polyester blend, one uses TENCEL that is a type of Rayon, and the fourth uses REPREVE® that is basically recycled bottles made from PET (which is what polyester is made from).

Brooklyn Bedding Mattress

Brooklyn Bedding’s response:
“We use a hydrated silica fiber sock around our mattress as our FR material. This material does not contain fiberglass and is non-toxic with no sprays.. We do not use any chemical fire sprays or chemical retardants in our mattresses. Brooklyn Bedding only uses the highest quality fire-retardant socks, made of Non-Woven Silica / Rayon / Polyester / Cotton Blend. For more information regarding our fire retardant fibers, you can research Jones Fiber. Our mattresses are made here in the U.S. in Phoenix, Arizona.”

Brooklyn Bedding manufactures its mattresses without the use of any fiberglass, which is good, but they do use Rayon, Polyester, and non-woven Silica… plus Hydrated Silica? There’s a lot going on there..


Casper’s response:
“None of our mattresses contain any of the materials you listed in your question above, nor do our mattress covers. Our mattresses are designed in the USA… Due to how we function, many of our products are manufactured locally per the domain… We operate in Europe, Canada, and America currently, so it’s dependent upon where you purchase our mattress to an extent.”

Because numerous people have reported different models of Casper mattresses leaking fiberglass-like particles all over their homes, I decided to question Casper support further and got this response.

Casper’s 2nd response:
“Yes. The firesock is composed of an inherently fire resistant (FR) rayon yarn with a fiberglass core, blended with small amounts of polyester and modacrylic. The fiberglass is fully encapsulated in the FR Rayon fiber, so no fiberglass should be exposed. In the event of a fire, these fibers are designed to char and form a barrier over the foam, preventing the flame from spreading into the foam layers.”

Casper uses fiberglass in its mattresses, plain and simple. Any website stating otherwise just wants to sell you a Casper mattress, or just doesn’t do very thorough research for their mattress articles.


CHITA’s response:
“All of the mattresses are free of fiberglass and all made in Mexico.”

CHITA ignored most of my questions and just assured me their mattresses don’t contain fiberglass..

Classic Brands

Classic Brand’s response:
“Yes as a fire retardant we use fiberglass underneath the scrim of the cover. We do not use any spray products on our mattresses.”

Classic Brands freely admitted they make mattresses using fiberglass as a fire retardant. They ignored the question regarding where mattresses are manufactured, but the Classic Brands FAQ page says China or USA depending on the mattress.

Diamond Mattress

Diamond Mattress’ response:
“Our products/fire retardants do not contain any fiberglass, Modacrylic, or Silica. We do have polyester and rayon in some products. We do not use any fire retardant sprays. Our mattresses are made in the U.S.A since 1946.”

Diamond Mattress manufactures fiberglass-free mattresses that are also free of modacrylic and silica. The Lagoon line of mattresses use Repreve fabric which is made from recycled PET bottles turned into polyester. However, the Sage Organic mattress by Diamond Mattress uses organic wool and cotton.

Dreamfoam Bedding

It appears that Dreamfoam Bedding is owned and/or operated by Brooklyn Bedding because that’s who responded to me via email after using the contact form on Dreamfoam Bedding’s website.

Dreamfoam Beddings’ response:
“We do not use any chemical fire sprays or chemical retardants in our mattresses. Brooklyn Bedding only uses the highest quality fire-retardant socks, made of Non-Woven Silica/Rayon/Polyester/Cotton Blend. For more information regarding our fire retardant fibers, you can research Jones Fiber. Our mattresses are made here in the U.S. in Phoenix, Arizona.”

Dreamfoam Bedding (Brooklyn Bedding) sort of dodged the questions and gave me the same cookie cutter response that I received regarding Brooklyn Bedding products. So Dreamfoam makes mattresses without the use of fiberglass, but there’s still silica, Rayon, and Polyester to be concerned about.

Eco Terra

Eco Terra’s response:
“We source our latex in Sri-Lanka, but the mattress is assembled and handcrafted here in our warehouse in Camarillo, CA. The mattress does not contain any fiberglass, etc. It’s made of all natural latex, organic wool and cotton. We only use organic wool as natural fire barrier.”

Eco Terra manufactures fiberglass-free mattresses and uses organic wool and cotton to make its natural latex fire-retardant. Nice!

Emma Sleep

Emma Sleep’s response:
“Top/sides: 99% Polyester, 1% Elastane. Bottom: 100% Polyester. Inner Linning: 60% modacrylic, 40% silica.”

Emma Sleep’s foams and mattresses are made without fiberglass. However, when asked what its firesock was made from I received the above answer. Emma Sleep’s mattress firesocks contain modacrylic.


GhostBed’s response:
“We do not apply or use any chemicals to comply with the Government’s Fire Regulations. We use a glass fiber scrim on the inside of the mattress. As for where we manufacture our mattresses we manufacture them in U.S.A and Canada.”

GhostBed uses fiberglass in its mattresses, other questions went unanswered aside from the location of manufacturing.

Good Morning

Good Morning’s response:
“Our mattresses do contain Modacrylic, Polyester, Rayon, as well as Silica in our Novosbed. As for Fire Retardant sprays none of our mattresses contain anything of this nature, as well as fiberglass. “

Good Morning mattresses are made without any fiberglass but do contain modacrylic, polyester, rayon, and the Novosbed mattress also contains silica.


HELIX’s response:
“All Helix foams are made in the USA; steel springs are made in the USA (though we are sourcing some now from Canada); fabrics are made in the USA (some Canada for Luxe).. Our Standard Helix mattress models do contain fiberglass in the flame retardant layer of the mattress. The fiberglass is enclosed in polyester fibers.. Our Helix Luxe and Plus models do NOT contain fiberglass. Instead, we use a flame retardant rayon with a derivative of cellulose (bamboo fiber).. To adhere to fire safety regulations, every Helix mattress has a fire retardant barrier. Rather than a chemical spray, we use a flame retardant sock that smothers flames – this prevents oxygen from feeding the fire and keeps the flames from spreading to the foam. The sock is made of a silica-based fabric..”

HELIX plainly stated its Standard line of mattresses contain fiberglass and polyester, and that the Luxe and Plus Helix mattresses are made without fiberglass but do contain Rayon. All HELIX mattresses have a fire sock that contains silica.


Happsy’s response:
“We do not use any flame barrier wraps or chemical flame treatments and we meet flammability standards by using USDA certified organic wool and with mattress design. In terms of synthetics.. we do not use any synthetics, fabric or chemical, to achieve flammability standards. We never have, or will, use any type of memory foam or polyurethane foam (you couldn’t be certified to the Global Organic Textile Standard or GOTS if you did), and our foam is 100% natural Dunlop latex. Our mattresses are all made in Ohio and our single manufacturing plant. Latex, of course, is sourced from places where rubber trees grow, so could include South America, Sri Lanka or Vietnam. Our mattresses, not just their components, are fully certified organic and nontoxic to GOTS.”

Well that’s pretty cut and dry – Happsy makes its mattresses that don’t contain any fiberglass, flame retardant chemicals, or anything that could be considered even remotely harmful.


Inofia’s response:
“All our mattresses are made of healthy, safe and environmentally friendly materials, which are certified by CertiPUR-US. But our company has many types of mattresses, in order to better solve your problem, we would like to know which one are you interested in?”

Inofia dodged the questions and asked me a question instead, so I followed up and said, “I just want a mattress that doesn’t have Fiberglass, Modacrylic, Polyester, Rayon, Silica, or Fire-Retardant Sprays on it. Do you sell one without all those materials?”

Inofia’s 2nd response:
“All our mattresses are made of healthy, safe and environmentally friendly materials, which are certified by CertiPUR-US. If you have any other problems, please feel free to contact us.”

Yeah, Inofia basically sent me the same reply as the first time. I’d avoid them.

Latex for Less

Latex for Less’ response:
“Our mattress is made of organic and natural materials. We are using natural wool as natural fire barrier. It is made here is our warehouse in California.”

I’m fairly certain this reply means there is no fiberglass, but to be sure I’ve asked again to get it in writing without assumptions!

Latex for Less’ 2nd response:
“No fiberglass or silica on our mattress. It’s just the natural wool that we used as fire barrier.”


LEESA’s response:
“Many of your questions can be found on our product pages or in the FAQs on our site. To answer your primary question about fire retardants: We do not chemically treat our materials, foams, or mattresses for any reason. The Original, Hybrid, and Legend mattresses are fully encased in a fire retardant sock made up of a proprietary blend of fibers, each chosen for its balance of comfort and flammability performance. Our proprietary fire barrier is an inherently fire-retardant fabric so it does not need or have additional chemical treatments.”

Oh I do enjoy being told the answers to my questions can be found on the FAQ page, even more so when that statement is complete bullcrap. The only answer to any of my questions found on LEESA’s FAQ pages was that mattresses are made in the USA – nothing else. I’ve marked LEESA as “unstated” in the table regarding fiberglass. I’ve also assumed LEESA’s proprietary “inherently fire-retardant material is Rayon, it’s always Rayon. I’ve replied to their email and will update this article accordingly if they reply with some actual answers.

LEESA’s 2nd response:
“Our fire sock does contain silica in order to reduce the spread of fire if it were to come into contact with the mattress. Our covers also contain modacrylic and polyester. We do not chemically treat any of our mattresses or products and are Certi-PUR Certified.”

But really LEESA just uses Silica and Modacrylic as code for fiberglass, read about it here:


Linenspa’s response:
“There are no harmful chemicals or fire retardants used in the manufacturing of the product. The only one with the fiberglass fire retardant and that is the 5″ gel memory foam mattress. The rest have a non removable cover… They are a treated cotton”

Linenspa says they make their memory foam mattress without fiberglass except the 5″ Gel Memory Foam Mattress, which is oddly specific. However, they use a fire-retardant spray on the cotton covers, so that’s concerning. I must also note that lots of Amazon reviews for Linenspa beds have complaints about bedbugs arriving in the package..


LUCID’s response:
“Here is a list of mattresses that have a treated cotton fire-retardant cover instead of a fiberglass fire retardant:
5 inch Gel Infused Memory Foam, 6 inch Gel Infused Memory Foam, 8 inch Gel Infused Memory Foam, 10 inch Gel Infused Memory Foam, 10 Inch Plush Gel Infused Memory Foam”

Lucid basically said its only memory foam mattresses made without any fiberglass have a fire-retardant sprayed cotton instead. That’s not very good..

Milton Sleep Co

Milton Sleep Co’s response:
“To answer your questions our mattresses do contain memory foam but not latex. With respect the other items just about all mattresses contain Polyester, Rayon, and other manmade materials. I believe that at this time Milton MIB may not meet your needs.”

Milton Sleep Co just sort of ignored my questions and said that Milton mattresses probably aren’t the best choice for me. I take that response to mean that Milton Sleep Co mattresses probably contain fiberglass and other synthetic textiles.


Molblly’s response:
“The inner cover of our memory foam mattress contains fiberglass… In addition, we are a large mattress manufacturer in China and our mattresses are also made in our factory in China.”

Molblly stated that ALL of its mattresses contain fiberglass. Best to avoid Molblly..


Naturepedic hasn’t gotten back to me yet, but I found these statements on their website: “Through extensive research and creative product design, we’ve eliminated the need for fire retardant chemicals and flame retardant barriers in our products. In particular, we use materials such as organic cotton fabric, organic cotton batting, plant-based non-GMO PLA batting, and steel innersprings in place of memory foam, other forms of polyurethane foam and synthetic fabrics that have much higher fuel loads. Our materials tend to smolder instead of bursting into flames with very high heat release.” I will still update with their actual reply when received.


Nectar’s First response:
“None at all… NECTAR does not contain any flame retardant chemicals. Rather a proprietary sock that’s just under the cover. In the event of a fire, the sock melts on itself and suffocates”

Amazon reviews contain photos of Nectar’s tags showing Rayon and Polyester in the used materials.

Nectar’s Second reply:
“The proprietary sock does contain fiberglass”

So, who knows, really? Nectar says one thing, evidence proves otherwise, and then they change their story when confronted and apologize for “misinformation”. It would be safest to just avoid Nectar completely and assume ALL Nectar mattresses contain fiberglass.

Nest Bedding

Nest Bedding’s response:
“Our mattresses are fiberglass-free.. Some of our mattresses will contain non-chemical hydrogenated silica as the fire barrier.. As a note, you can have non-toxic options for Silica, Polyester and Rayon and some of our products will contain these.. Have you taken a moment to look through our options? Each page offers a Materials and Certifications subsection.”

Nest Bedding’s website did not have a readily available means to email them so I had to use the chat function. The “Nestologist” I was connected to seemed to be more interested in being my personal shopping assistant than actually answering my questions about materials used in making their mattresses. In the end I was able to find out that most of Nest Bedding’s mattresses contain silica as a fire retardant and are made from polyester or TENCEL (Rayon). Nest Bedding’s only mattresses made with cotton/wool are their Owl and Finch lines of beds, and those contain silica.

Nolah sleep

Nolah Sleep’s response:
“Your safety and comfort are important to us. We would never include fiberglass in our mattresses. We never have and never will.
Silica is used in the Original, Signature, and Evolution mattresses as a fire retardant, while our Natural and Nurture mattresses use organic wool for the same purpose.
Yes, polyester is used in our foam mattresses and their covers. Our Natural and Nurture mattresses are made with natural latex, organic cotton and wool, and recycled steel, so they do not have polyester.
Also, we don’t use any kind of fire retardent sprays.
I’m not able to find anything definite regarding modacrylic or rayon right now, but I’d be happy to investigate further and email you you more information if you’d like.”

Evidence from customers and other websites suggest the use of Modacrylic, as well as Rayon/TENCEL, in the Original/Signature/Evolution lines. However, the Natural and Nurture lines from Nolah Sleep do not contain fiberglass and are made without other questionable materials.


Novilla’s response:
“Novilla provides the best ECO Friendly & Organic products (as we manufacture our product using antibacterial, hypoallergenic, CERTIPUR-US Certified, OEKO-TEX Eco-Friendly materials) are relatively high within the industry… Our products are made in Indonesia, Malay, Vietnam, Cambodia, Brunei and so on.”

Novilla pretty much dodged the important questions and only told me where the mattresses are made, which is several countries in South-East Asia. I’ve made a reply with my unanswered question restated to try and pry more information and will update this article accordingly once they reply!

Novilla’s 2nd response:
“Our products do not contain fiberglass. What fire retardant is currently used, the factory has not clearly pointed out..”

MY thoughts are that Novilla mattresses probably contain fiberglass.

Olee Sleep

Olee Sleep’s response:
“Our mattresses do contain: Fiberglass (fire retardant material), Polyester, Spandex, Acrylic in the cover components. Our mattresses are manufactured in Indonesia.”

Olee Sleep mattresses contain Fiberglass and Polyester according to an email reply I got from them. Moving along..

Perfect Cloud

Perfect Cloud’s response:
“We use a fire-retardant mattress lining or sock that goes around the mattress. It’s made of a special fiberglass material. This is in order to conform to fire retardant standards. It is under the cover there wouldn’t be any contact to the fiberglass. Our mattresses are made in the USA”

Perfect Cloud mattresses contain “special” fiberglass. I’m not even going to follow up about Modacrylic/Polyester/Rayon/Silica.


PlushBeds’ response:
“Yes all our Latex mattresses are made without any use of fiberglass materials. And also both our Memory Foam mattresses are fiber glass free as well… Exceeding safety standards doesn’t require toxic chemicals or fire barriers made from fiberglass. Our patented Eco Fire Barrier is derived from natural plant fibers to keep you safe, secure, and healthy.”

PlushBeds sells mattresses made without fiberglass that use wool as a fire retardant, however, its vegan mattresses have the wool replaced with an “Eco Fire Barrier” derived from natural plant fibers which I can only assume is Rayon until they respond to my follow-up questions. The mission page of their website describes its California, US, manufacturing facility.

PlushBeds’ second reply:
“We apologize but unfortunately as per our Warehouse and Production Departments, we are not allowed to give further information regarding the FIBERGLASS-FREE ECO FIRE BARRIER™ since it is a proprietary information.”

So.. PlushBeds got back to me and apparently the plant-based “Eco Barrier” is some highly guarded trade secret, which it can’t be since it has to be listed on the tag… Best bet is still that it’s Rayon, but who really knows? I’d pass on the PlushBeds Vegan options..

Puffy Mattress

Puffy Mattress’ first response:
“Our mattresses are 100% made in the USA and are CertiPUR-US® certified. I have included two links below for more information on the construction of our mattresses and their materials.”

Puffy Mattress either avoided the question or they’ve hired lazy people to do support, because I’d already been to the pages that the links pointed. My questions was not answered there which is why I emailed them in the first place. I replied to their email and waited for a reply.

Puffy Mattress’ second reply:
“As we mentioned before, our mattresses are 100% CertiPUR-US certified. And you can check on the website all the materials that negate the certification, as well as what the foams have to go through to be certified. All the info that you need and asked bout is on their website:

Puffy basically gave me the “as I said before” treatment with the same copy/paste reply as the first response. I replied one last time to give them a chance to actually answer my questions before writing them off as a member of the “Avoid at all Costs” bed-in-a-box brands.

Puffy Mattress’ third reply:
“Thank you for your reply. It is stated under our “How Its Made” webpage that we do not use flame retardants. The foam layers are encased in a firesock that is comprised of silica and wool threads. The mattress has a polyester cover that completely encloses and covers the firesock.”

After THREE emails Puffy finally gave the answers to my questions, answers which were definitely not on the “How It’s Made” page like the representative seems to believe. However, it was brought to my attention that another person got this reply to my fiberglass questions: “Fiberglass is encapsulated into the core-spun yarn of the fire sock”. I reached out to Puffy again and after two weeks without a reply I made the decision to agree that Puffy mattresses probably contain fiberglass.


Sealy’s response:
“Sealy mattresses are designed and built in the U.S.A.”

Aside from revealing the country mattresses are manufactured in, Sealy dodged the other questions and didn’t reveal any info about Fiberglass use or Modacrylic/Silica/Rayon/Polyester.

Signature Designs (by Ashley)

Signature Design’s response:
“Ashley’s upholstered furniture is designed and labeled to comply with California’s TB 117-2013, and we are committed to designing our upholstered furniture with the goal of meeting the requirements of TB-117-2013 without the use of flame retardant chemicals. To that end, Ashley is pleased to announce that after working closely with our supply chain, upholstered furniture manufactured by or for us as of January 1, 2015, does not use flame retardant chemicals. In addition, all our upholstered furniture, no matter where it is shipped in the US, includes a label that complies with the requirements of California’s SB-1019”

Signature Designs by Ashley basically just dodged the questions and gave me the brochure copy/paste treatment. However, there are numerous reports on reddit and in Amazon reviews of peoples’ homes being contaminated by fiberglass-like particles coming from their Signature Designs mattress. So it’s safe to say Signature Designs mattresses contain fiberglass, or something just as dangerous. It’s no wonder why they avoided my questions.. ?

Signature Sleep

Signature Sleep’s response:
“Our Signature mattresses are manufactured in China… The FR barrier sock is made with a knitted process with 50% Modacrylic/50% Glass yarns (+/-10%). The Glass and Modacrylic yarns are used in the thread form on a small rolls and the final product is a kind of knitted (or woven) fabric.”

Signature Sleep was perhaps the most forthcoming of all the bed manufacturers, they didn’t try to dodge questions and were the only manufacturer to give the amounts of Fiberglass and Modacrylic used based on percentages. Signature Sleep mattresses contain fiberglass, for sure..

Silk & Snow

Silk & Snow’s response:
“All our mattresses are compliant with all fire safety standards across Canada and the United States. For US customers, this means that our mattresses are encased with a fire sleeve, which uses a textile comprised of CFF (continuous filament fiberglass)… For Canadian customers, our mattresses do not use any sort of fire sleeve, as fireproofing is not required under Canadian legislation. For our organic mattress, we use New Zealand wool, which acts as a natural fire retardant.”

Silk & Snow mattresses are fiberglass-free for Canadian customers. However, for customers in the US, Silk & Snow’s only option without fiberglass is the Organic option that uses wool as a flame retardant. Questions regarding its other materials were not answered, but mattresses are manufactured in Ontario, Canada.

Sleep on Latex

Sleep on Latex’s first response:
“We only sell latex mattresses that are made with 100% natural latex. There is no memory foam or synthetic latex added at all.
The liquid latex is harvested from rubber trees in Sri Lanka and the foam is made in and shipped from Malaysia.
Our latex does not contain fiberglass or any other similar materials in the cover or mattress. The cover is made with 100% organic cotton and 100% organic wool.”

Sleep on Latex makes its mattresses without relying on fiberglass as a flame barrier and that’s a great choice! I have responded to their email and asked follow-up questions just to make sure there are no fire-retardant sprays used, but seeing as wool is naturally fire retardant, I think I already know that the answer will be “no”.

Sleep on Latex’s second reply:
“Our mattress does not contain rayon, modacrylic, or silica. The cover has a zipper and the zipper tape is made of 100% polyester. Besides that, the cover fabric is 100% cotton and wool! We do not use any fire retardants. The wool in the mattress cover is enough to pass flammability tests.”

There you have it – no fire retardant sprays, rayon, and the only bit of polyester is the cover zipper which is why I’ve left the Sleep on Latex table entry as a “No” for polyester since most of the mattresses covered in this article probably have polyester zippers.


Spindle’s response:
“Manufacturer: Spindle Mattress
Fiberglass: NO
Modacrylic / Silica / Rayon / Polyester: NO
FR Chemical Spray: NO
Countries of Origin:
-Mattress manufactured in the USA.
-Components: USA, Canada, Sri Lanka, India, and New Zealand”

That is the reply I got from Spindle – very structured, no? I’ve checked their website for any inconsistencies and haven’t found any, therefore Spindle is a really good choice because it makes mattresses without relying on fiberglass or any other materials of concern!

Stearns & Foster

Stearns and Foster’s response:
“Conversely, the glass fibers in our mattress products are comprised of a core-spun technology that encases the glass in a flexible protective sheath housed within the internal mattress design, and is completely safe and inaccessible in normal use, even if the cover is removed. To ensure safety and quality for our customers, Stearns and Foster only uses this core-spun glass fiber technology, and regularly conducts independent testing to ensure continued safety, and that the materials within all Tempur Sealy products meet or exceed all regulatory compliance.”

Stearns & Foster’s reply about the materials in its flame barrier is an exact copy and paste of the same reply from it’s sister companies Sealy and TempurPedic.

Sunrising Bedding

Sunrising Bedding’s response:
“We don’t have any fiberglass or chemical materials in the cover. Sunrising Bedding 8 inch and 10 inch mattress cover is made of pure Cashmere wool. Our mattress is manufactured in Malaysia.”

However, Sunrising Bedding’s website FAQ clearly states:
“The mattress is made in China. But it is CertiPUR-US certified that means it is made of safe materials and qualified for physical performance. We ensure it the same quality as U.S. mattresses.”

I’ve also found on their comparison page that only the Latex Hybrid and Luxury Hybrid lines of mattresses use Cashmere wool while the Euro-Top and Memory Foam lines of mattresses use TENCEL which is a form of rayon. So, Sunrise Bedding makes all of its free of fiberglass, but just be mindful if you’re also avoiding Rayon!


Sweetnight’s response:
“As far as manufacturing is concerned, most of our products are made in Malaysia. Also, our mattresses contain no fiberglass at all. We took it off once the study suggests this material might be a health threat.”

It’s good that Sweetnight has transitioned to making fiberglass mattresses, however they still avoided answering the part of the question about Modacrylic, Rayon, Polyester, and FR Sprays like Antimony. I replied with follow-up questions to get more information and will update when I get a response!

Sweetnight’s second reply:
“We don’t use Modacrylic, Polyester, Rayon, or Silica in our mattresses. We use fire retardant cotton.”

So they still avoided the FR Spray part of the question… but since they use a fire retardant cotton I can guess the answer pretty easily. I’ve replied once more and plainly asked “How is the cotton made to be Fire Retardant?”, we’ll see what happens.

Sweetnight’s third reply:
“We use technology to add fire-resistant material to the foam layer of the mattress.”

Well then, so apparently the cotton isn’t fire retardant, but instead, it’s the foam?… I’ve replied with “So what is the technology used to add what fire-resistant material to the foam layers of the mattress?” but I have a feeling I’ll just be ignored because it’s fiberglass.


Tempur-Pedic’s reply:
“Our formula is not public knowledge. Tempur-Pedic product formulas are a trade secret; however, the raw materials and processes used in manufacturing Tempur-Pedic products are similar to those used in the production of a large variety of polyurethane foams used every day by millions of people in many different applications like furniture, bedding, carpet underlay, packaging and automotive seats. Tempur-Pedic products do not contain polybrominated diphenyl ethers (PBDEs) and our products meet fire safety requirements without using PBDEs. All Tempur-Pedic products are designed and manufactured to meet applicable Federal, State and local regulations (including California Prop 65).”

Tempur-Pedic completely dodged the questions and replied to me with a cookie cutter cut-and-paste reply that revealed no information about the country of origin nor materials used in the manufacturing processes. However, with more precise questioning I was able to get this nugget of transparency out of Tempur-Pedic.

Tempur-Pedic’s 2nd reply:
“To comply with the Consumer Product Safety Commission fire safety regulations, some manufacturers rely on exposed, brittle, easily crumbled fiberglass (a cheap technology that has made headlines in the past with dermal exposure and rashes). Conversely, the glass fibers in our mattress products are comprised of a core-spun technology that encases the glass in a flexible protective sheath housed within the internal mattress design, and is completely safe and inaccessible in normal use, even if the cover is removed. To ensure safety and quality for our customers Tempur Sealy only uses this core-spun glass fiber technology, and regularly conducts independent testing to ensure continued safety, and that the materials within all Tempur Sealy products meet or exceed all regulatory compliance.”

Tempur Sealy admits that Tempur-pedic mattresses do in fact contain fiberglass. This information is in direct contrast to what most other mattress selling websites report regarding Tempur-Pedic and fiberglass. Sometimes you just have to ask the right questions to get answers. Read more about Tempur-Pedic’s fiberglass here.

Tuft & Needle

Tuft & Needle’s response:
“We manufacture our mattresses here in the US and do not use fiberglass, modacrylic, or silica in any components of our Original T&N or Mint mattress models… Our firesock is actually crafted with a polyester/cotton blend knit fabric, treated with a food grade salt.”

However, I have found that many of the Original mattresses had Fiberglass up until 2017, and some of those are probably still floating around in warehouses and being sold. Another worrisome finding is listings on Sam’s Club for “Tuft & Needle X Sam’s Club” mattresses containing continuous glass filament, which is just a weird way of saying Fiberglass.. So while T&N may have removed Fiberglass from the main product lines of mattresses, Sam’s Club is selling cheaply made mattresses that do contain fiberglass with Tuft & Needle’s name slapped on them at the cost of customers’ safety..


Tulo’s response:

Tulo’s website redirects to MattressFirm, and MattressFirm makes it pretty difficult to get in touch aside from calling their sales telephone number. I’ve tried chatting, but it never works. For now I’d just assume Tulo’s cheap prices mean they do NOT make fiberglass-free memory foam mattresses. Maybe they’ll read this and get in touch with me instead? Haha, probably not..


Zinus’ response:
“All our mattresses contain glass fiber.”

Regarding where Zinus beds are made, its website states:
“Right now, our product designers are based in South Korea and our manufacturing factories are in Xiamen, China.”

So, all Zinus mattresses contain fiberglass, and they didn’t even bother answering my other questions.

Update: Zinus has recently had a class-action lawsuit filed against them for the many people that have had health issues and lost their homes due to Zinus firesocks being damaged and releasing fiberglass particles. With that in mind, I’d probably avoid Zinus for now, and maybe look into filing a claim if you own a Zinus mattress.


Zoma’s response:
“We use a FR sock that is made from Cotton/Polyester. PyroGuard is manufactured without the use of glass, silica loaded rayon, modacrylic, melamine, antimony, phosphorous or chlorine. It is compliant to California Proposition 65, Oeko-Tex 100 standards and Washington State CHCC.”

Zoma assured me its mattresses don’t have fiberglass, so I asked how its fire socks meet flammability standards. Zoma says its mattress firesocks use a cotton and polyester blend to pass flammability tests.
