Does Bear Elite Hybrid Use Fiberglass? Flame Barrier
Review of Bear Elite Hybrid mattress fire barrier textiles, WhisperShield technology, and law tags.
100% Fiberglass-Free
Direct answer summary
The Bear Elite Hybrid does not contain fiberglass or synthetic glass fiber socks. Bear Sleep utilizes a proprietary flame barrier known as WhisperShield, constructed from inherently flame-resistant cellulosic rayon and bonded polyester. When subjected to CPSC 16 CFR Part 1633 test burners, the WhisperShield barrier chars to create an oxygen-depleting barrier that shields the underlying comfort foams and pocketed coil core.
Key points
WhisperShield fire barrier uses cellulosic rayon and bonded polyester fibers.
Zero fiberglass, chopped glass fibers, or antimony trioxide retardants.
Entire mattress is certified under CertiPUR-US and GREENGUARD Gold.

Checklist
Consumer Safety & Chemical Verification Protocol
Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.
- 01
Verify WhisperShield Layer
Review the law tag stitched on the lower border for rayon/polyester disclosures.
Watch for: Do not attempt to dry-clean the outer hand-tufted cover.
- 02
Inspect Micro-Seam Binding
Ensure perimeter tape edging is tightly stitched without inner batting leakage.
Watch for: Avoid running vacuum beaters across delicate Celliant cover fibers.
- 03
Review Facility Compliance
Cross-reference URN VA-045210 with active Arizona bedding production registry.
Watch for: Do not trust unauthorized gray-market liquidator tags.
