Does MLILY Use Fiberglass? No, Phosphates Used Instead. may earn commissions from Amazon and other affiliates through links in this article.

MLILY is a very popular brand of mattresses, gaining most of its popularity as an affordable sleep option on Amazon.

Many potential consumers voiced concerns about potential fiberglass use by MLILY before making a purchase, so I decided to look into the possibilities.

MLILY Fiberglass Initial Check

A mattress seller’s website is always the first place I check for information on fiberglass. Product pages, Certification pages, and the Frequently Asked Questions (FAQ) page are always the best places to start.

However, aside from a few mentions on product pages and Amazon listings, there wasn’t a lot of information given about fiberglass.

I decided to just contact MLILY and straight up ask about its mattress materials and where they are made.

These are the questions I asked MLILY:

“Do any of your mattresses contain Fiberglass, Modacrylic, Polyester, Rayon, or Silica in the covers or any other part of the mattress? What about Fire Retardant sprays like Antimony, are any of them used on your mattresses? What countries are your mattresses made in?”

MLILY replied to me without delay and had this to say:

MLILY Fiberglass Free Email

“Our Mattresses do not contain any fiberglass. The foams are poured here in the USA, we do not use any heavy metals in our production. We use amidino urea phosphate and Ammonium polyphosphate as flame retardants in our firesock. We do use rayon fiber and polyester in our textiles and foam. We do not use silica, modacrylic, or fiberglass in production.”

MLILY states it does not use fiberglass, which I’m inclined to believe. However, use of Amidino Urea Phosphate and Ammonium Polyphosphate definitely warrants closer inspection.

MLILY Uses Phosphates

Ammonium Polyphosphates seem to be regarded as mostly harmless. However, it turns out that Amidino Urea Phosphate is actually spelled “Amidinourea Phosphate”, and it’s also known as Guanylurea Phosphate. There isn’t a lot of information online about the Guanylurea Phosphate that MLILY uses, but MSDS sheets state it causes skin irritation, eye irritation, as well as respiratory irritation.

I would be concerned about spending a third of each day on a mattress that contains Amidinourea Phosphate.
