For Cocoon™ by Sealy models and hybrid mattress models (i.e. contain both foam + innersprings):
These models don’t contain any form of fiberglass. The flame barrier used in these mattresses are a rayon and polyester blend.
For all other foam-only models:
Tempur Sealy selects raw materials and manufactures with safety, quality and the environment in mind. All Tempur Sealy products have been evaluated to comply with all laws and regulations, including the Consumer Product Safety Commission and California Proposition 65.
To comply with the federal fire safety regulations, some other manufacturers rely on exposed, brittle, easily crumbled fiberglass (a cheap technology that has made headlines in the past with dermal exposure and rashes). Conversely, the glass fibers in Tempur mattress products are comprised of a core-spun technology that encases amorphous glass in a flexible protective sheath housed within the internal mattress design, and is completely safe and inaccessible in normal use, even if the cover is removed. To ensure safety and quality for our customers Tempur Sealy only uses this core spun glass fiber technology, and regularly conducts independent testing to ensure continued safety, and that the materials within all Tempur Sealy products meet or exceed all regulatory compliance. This is used in the protective fire-sock and is not in the foam or cover.
