I looked for brands that clearly state fiberglass-free on the product page and in FAQs. If the listing is vague, I skip it. A mattress is too hard to return and too personal to gamble on hidden materials.
How do you know if a mattress is really fiberglass-free?

I keep reading scary comments about fiberglass in cheap mattresses. Some brands say CertiPUR-US, but I don’t know if that means fiberglass-free or just foam safety.

People discuss how to check whether a mattress is fiberglass-free and why certifications may not answer every material question.
Answers & Discussion
Also check whether the cover is removable. Some mattresses warn not to remove the cover because the fire barrier is inside. That does not always mean fiberglass, but it is a signal to ask more questions before buying.
Do not rely only on marketing wording. Ask the brand directly what the fire barrier is made from and get the answer in writing. CertiPUR-US is about foam content and emissions, but it does not automatically mean the whole mattress is fiberglass-free.
