Beautyrest Harmony Lux Fire Barrier Materials Audit
Analysis of Beautyrest Harmony Lux Seaqual fabric, FlameGuard barrier, and fiberglass-free construction.
100% Fiberglass-Free
Direct answer summary
Beautyrest Harmony Lux mattresses do not contain fiberglass. Serta Simmons Bedding (SSB) utilizes a proprietary non-woven flame barrier composed of cellulosic wood-pulp rayon fibers blended with polyester and treated with water-soluble mineral salts. Under CPSC 16 CFR Part 1633 open flame testing, this barrier creates an impenetrable char matrix that prevents flame propagation into the pocketed coil and memory foam layers.
Key points
Barrier utilizes an inherently flame-resistant cellulosic rayon and poly fiber blend.
Features Seaqual sustainable ocean plastics in ticking without glass fibers.
Certified fully compliant with CPSC 16 CFR Part 1633 without chemical retardants.

Checklist
Consumer Safety & Chemical Verification Protocol
Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.
- 01
Inspect Ticking and Seams
Confirm the law label lists cellulosic rayon and polyester in the barrier specification.
Watch for: Do not remove or unzip the quilted Seaqual surface cover.
- 02
Examine Perimeter Edge Seam
Ensure the heavy tape-edge binding is firmly stitched without batting protrusion.
Watch for: Never use harsh chemical solvents on surface knit fibers.
- 03
Check SSB Plant Registration
Verify the factory URN code corresponds to Serta Simmons Bedding plants.
Watch for: Avoid purchasing unbranded clearance mattresses without law tags.
