Query: “sealy posturepedic fiberglass in mattress cover”

100% Fiberglass-Free

Direct Answer Summary

Modern Sealy Posturepedic mattresses do not contain loose or frangible fiberglass in their covers. Tempur-Sealy utilizes a proprietary flame-retardant fiber system known as FlameGuard, composed of modacrylic and cellulosic rayon fibers infused with amorphous silica. When exposed to the intense heat of CPSC 16 CFR Part 1633 burners, FlameGuard fibers expand and char, forming a thermal barrier that blocks flame penetration.

Audited Core Takeaways

  • 1FlameGuard technology utilizes modacrylic and silica-viscose fiber blends.
  • 2Contains zero continuous glass filament or frangible glass needle felt.
  • 3Manufactured across domestic Tempur-Sealy plants under strict quality audits.

Safety Inspection Protocol3 Actionable Steps

Consumer Safety & Chemical Verification Protocol

Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.

Inspect Foot-End Law Tag

Step 1

Locate the permanent TSI law tag stitched into the lower tape-edge seam.

Critical Hazard to Avoid

Do not attempt to machine-wash the quilted euro-top panel.

Examine Quilted Ticking

Step 2

Verify that surface knit contains clean polyester and cotton without fiber leakage.

Critical Hazard to Avoid

Never puncture the inner quilted FlameGuard barrier layer.

Check Manufacturer URN

Step 3

Confirm URN maps to authorized Tempur-Sealy production facilities in TX, NC, or OH.

Critical Hazard to Avoid

Beware of re-covered liquidation beds with counterfeit labels.
