Analysis of Helix Midnight Luxe fire barrier materials, Arizona factory URN registration, and fiberglass disclosure.
The Helix Midnight Luxe contains zero fiberglass. Helix Sleep updated its manufacturing formulations across its Arizona 3Z Telecom facility to utilize an inherently flame-resistant rayon and modacrylic fiber barrier. The fire barrier operates by thermally decomposing into carbon char when exposed to open flame, meeting CPSC 16 CFR Part 1633 calorimeter benchmarks without the use of woven glass filament or chemical flame retardant sprays.
Manufactured with a modacrylic and rayon charring fiber blend.
100% fiberglass-free across all Luxe and Elite tier configurations.
Assembled in Phoenix, Arizona under active URN registry VA-045210 (AZ).
