16 CFR Part 1633
Tuft & Needle Flame Barrier & Chemical Disclosure
Breakdown of Tuft & Needle Original mattress flame barrier, chemical safety, and CertiPUR-US testing.
100% Fiberglass-Free
Direct answer summary
Tuft & Needle mattresses do not contain fiberglass. The Tuft & Needle flame barrier is engineered from an inherently fire-resistant non-woven blend of cotton, polyester, modacrylic, and continuous cellulosic fibers infused with food-grade hydrated silica. Under CPSC 16 CFR Part 1633 flame testing, this barrier creates an oxygen-starving carbon char layer without chemical fire retardant sprays or glass filament release.
Key points
Fire barrier utilizes a blend of cotton, polyester, and hydrated silica rayon.
100% free of glass fibers, continuous glass filament, and PBDEs.
Certified by CertiPUR-US and GREENGUARD Gold for extremely low chemical emissions.

Checklist
Consumer Safety & Chemical Verification Protocol
Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.
- 01
Review Law Label Breakdown
Confirm the filling materials breakdown specifies cotton, polyester, and rayon fibers.
Watch for: Do not detach the statutory law tag from the mattress border.
- 02
Inspect Outer Micro-Knit
Verify that the cover is secure and free of abrasive needle punctures.
Watch for: Avoid liquid chemical spot treatments that degrade foam cell structure.
- 03
Check Batch Production Date
Match production batch code on law label with official Serta-Simmons safety filings.
Watch for: Never store mattress in non-ventilated humid environments.
