Since Sealy seems to avoid the topic of fiberglass on their website, almost to a point of suspicion, it can be hard to discern whether they use it or not. But, Sealy support directly admits the use of fiberglass in its mattresses.

Purple states it only uses “natural fibers” in its flame barriers, but doesn’t actually say what the natural fibers are… is it fiberglass?

Vaya is the sister company to Amerisleep and Zoma, and all three of them use the same Polyester/Cotton Flame Barrier instead of Fiberglass.

Zinus told me that its mattresses still consist of a fiberglass flame barrier. The lawsuits never stopped Zinus from using fiberglass, they just forced Zinus to adequately label their products. However, Zinus is transitioning to a Rayon.

I contacted Mattress Firm about Fiberglass in Sleepy’s and Tulo mattresses, and Mattress Firm confirmed fiberglass use in both!

Tulo mattresses definitely have fiberglass, but some popular websites might lead you to believe they are fiberglass-free when they are not. I wanted to cut through the smoke and mirrors, so I went straight to the source to find out about the fiberglass in Tulo mattresses.

If Sleep Number beds were fiberglass free, they’d be happy to tell you. But, Sleep Number just says fiberglass is proprietary information.

Fiberglass is dangerous and unsafe, but mattress makers still use it as a cheap means to pass flammability tests at the cost of our health while contaminating our homes.
