Mattress Safety & Materials Guide
How to interpret fiberglass, foam certification and fire-barrier claims without panic or marketing hype.
Start with the law and the label
Mattresses sold in the U.S. must meet federal flammability requirements, but manufacturers can use different compliant constructions. If fiberglass is a concern, verify the exact model's current materials with the manufacturer.
What CertiPUR-US means
CertiPUR-US is a certification program for flexible polyurethane foam. It is not a blanket certification of every component in an entire mattress.
Material and safety questions deserve precise sourcing. Do not cut or remove mattress covers contrary to manufacturer instructions.
