16 CFR Part 1633
Birch Natural Organic Wool Fire Retardant Audit
Analysis of Birch Natural hybrid mattress flame barrier, organic wool properties, and OEKO-TEX testing.
100% Organic & Chemical-Free
Direct answer summary
The Birch Natural mattress does not use fiberglass, chemical flame retardants, or synthetic fire socks. Birch relies on organic and natural wool fibers blended with rayon as its primary flammability barrier. Wool contains natural keratin proteins that absorb thermal energy and char into an insulating barrier under CPSC 16 CFR Part 1633 testing, preventing flames from igniting the underlying natural Talalay latex core.
Key points
Natural wool char barrier replaces all synthetic glass fiber and chemical additives.
Contains certified organic materials with OEKO-TEX Standard 100 certification.
Meets strict CPSC 16 CFR 1633 open flame requirements through physical charring.

Checklist
Consumer Safety & Chemical Verification Protocol
Step-by-step physical inspection procedure for flame barrier integrity and law label compliance.
- 01
Inspect Law Tag Filling Details
Confirm filling materials state natural wool, rayon, and natural latex rubber.
Watch for: Do not use steam cleaners on raw natural wool fire layers.
- 02
Examine Cotton Cover Stitching
Check that the organic cotton cover is firmly quilted to the wool fire barrier.
Watch for: Avoid pulling loose wool tufts from border seams.
- 03
Verify Certifications Database
Check OEKO-TEX and Eco-Institut databases for active Birch certification numbers.
Watch for: Never buy uncertified natural mattresses lacking statutory tags.
