TEMPUR-Pedic Mattress Fiberglass or Silica Sock Audit
Review of TEMPUR-Pedic mattress fire barrier knit sleeve, silica construction, and law tag disclosures.
100% Fiberglass-Free
Direct answer summary
TEMPUR-Pedic mattresses do not contain fiberglass. Tempur-Sealy International's published law labels and disclosures for TEMPUR-Adapt, ProAdapt, and LuxeAdapt models describe a proprietary fire-retardant sock knitted from viscose-rayon fibers embedded with amorphous silica. When exposed to open flame under CPSC 16 CFR Part 1633, the silica vitrifies into an inert barrier that smothers flames without releasing sharp crystalline glass dust.
Key points
Fire-retardant sock is knitted from viscose-rayon embedded with amorphous silica.
100% free of glass fibers, continuous-filament glass, and chemical sprays.
Certified under OEKO-TEX Standard 100 and CertiPUR-US for chemical safety.
