Spring Air’s Glass-Free Mattress Barriers
U.S. law demands every mattress resist open flame, but most brands still hide fiberglass under the cover. Spring Air went glass-free: each model uses either the stretch-knit IQFit Glass Free sock or the hi-loft Celluloft-FR NanoShield panel—both pass 16 CFR 1633 without glass shards.
1. Why Ditch Fiberglass?
- Health & cleanup hassles. Escaping fibers irritate skin and lungs, cling to carpets and HVAC systems, and cost a fortune to remove.
- Regulation is material-agnostic. The CPSC sets a burn-time limit—not a required ingredient—so safer materials are welcome.
- Consumer backlash. Lawsuits and viral posts have created real demand for glass-free alternatives.
2. Option 1: IQFit Glass-Free Sock
Fiber content: 100 % inherent FR rayon—zero glass, zero chemical finishes.
Construction: 1 × 1 modified-rib knit that stretches to “glove-fit” the mattress core for uniform protection.
Certifications: CFR 1633, AB 2998, Prop 65 and UL GREENGUARD for low VOCs.
Peak char temp: ~ 800 °F, maintaining structural integrity under flame.
Why sleepers love it
- Breathable & flexible—won’t change mattress feel
- Zero-glass irritation, even if the outer cover is removed
- Eco-safer production—no halogens or antimony
3. Option 2: Celluloft-FR NanoShield Panel
Application: Hi-loft barrier quilted into panel and border fabrics—ideal for pillow-top or euro-top builds.
Fiber blend: 75 % inherent FR rayon, 24.5 % low-melt PET, 0.5 % patented silica-nanoclay particles for dual thermal defense.
Performance: Nanotechnology smooths the surface, slowing flame spread while delivering high char strength (400–600 °F char range).
Free of: Glass, antimony, bromine, deca-BDE, HCN, HCl and other toxins.
Why sleepers love it
- Plush feel complements quilted tops
- Enhanced edge aesthetics for retail wow-factor
- Chemical-free safety built right into the quilting
4. How Spring Air Chooses the Right Barrier
| Mattress style | Fire-barrier choice | Why this option? |
|---|---|---|
| All-foam & smooth-top hybrids | IQFit Glass-Free sock | Conforms tightly without altering feel |
| Quilted-panel, pillow-top or euro-top | Celluloft-FR NanoShield panel | Integrates seamlessly into high-loft quilting |
Either route guarantees CFR 1632/1633 compliance with zero fiberglass.
5. What This Means for You
- No fiberglass fallout—ever.
- Comfort stays intact—barriers flex or loft without trapping heat.
- Cleaner indoor air—third-party certified low VOCs.
- Peace of mind—30-minute open-flame protection is built into every Spring Air mattress.
Frequently Asked Questions
Is every Spring Air model fiberglass-free?
Yes. Each mattress uses either the IQFit Glass Free sock or the Celluloft-FR NanoShield panel—never fiberglass.
Do glass-free barriers cost more?
Materials are slightly higher, but Spring Air’s scale keeps prices competitive.
Will the barrier affect cooling?
No. The knit sock is breathable, and the NanoShield panel’s high loft maintains airflow.
Can I remove the cover to wash it?
No. Removing a sewn cover voids safety compliance and the warranty—spot-clean only.
How do glass-free barriers pass fire tests?
Inherent FR rayon swells and chars, blocking oxygen much like molten glass—but without shards.
