Brooklyn Bedding is a large mattress manufacturer, with many mattress brands under its scope that are known as 3z Brands.
I’ve been in contact with Brooklyn Bedding since 2019, and its mattresses rely on hydrated silica instead of fiberglass for flame barriers.
Brooklyn Bedding First Fiberglass Response
I contacted Brooklyn Bedding back in 2019 to ask about fiberglass use in its flame barriers.
These are the questions I asked Brooklyn Bedding:
“Do any of your memory foam mattresses contain fiberglass, modacrylic, or “silica” in the covers or any other part of the mattress? What countries are your memory foam mattresses made in?”
This was the first reply I received from Brooklyn Bedding back in 2019:
“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 Second Fiberglass Response
I asked Brooklyn Bedding this question in 2024:
“So, does Brooklyn Bedding have any documentation regarding its silica?”
This is the second response from Brooklyn Bedding:
“All mattresses are required by the federal government to use a type of FR (Fire Retardant Barrier). To ensure we follow this requirement, but also to ensure a healthy environmentally friendly product 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. One other thing to note is that hydrated silica is the same thing that is used in toothpaste and is not harmful.”

Brooklyn Bedding states it manufactures its mattresses without the use of any fiberglass, and I haven’t found any evidence online that suggests otherwise.

While shopping for his daughter’s first “big girl” bed in 2019, John learned about the hidden dangers of fiberglass in mattresses. Since then, he’s made it his mission to expose as much hidden fiberglass in mattresses as possible. His ultimate goal is federal regulations that ban fiberglass from being used in mattresses, or at least a law that requires it to be listed as a material on required tags.
