cphi-Sleep: Sovereign Natural Hybrid Sleep System
A clinical rejection of the "Foam Tax," fiberglass fire barriers, and petroleum-based bed-in-a-box mattresses.
The cphi-Sleep system is a complete DIY blueprint for building a durable, non-toxic natural latex hybrid mattress using 100% natural materials: Dunlop & Talalay latex, individually pocketed coils, and organic wool.
Why This Matters
Retail hybrids (Tempur-Pedic, Casper, Purple, etc.) routinely sell for $2,500–$4,500. Most are made of polyurethane foam that off-gasses VOCs, traps heat, and sags within 5–8 years, often with hidden fiberglass fire barriers.
cphi-Sleep replaces marketing abstraction with deterministic engineering: renewable natural latex, breathable open-cell structure, zero motion transfer coils, and a safe natural wool fire barrier.
Key Advantages
- Lifespan: 15–20+ years with modular, replaceable layers.
- Comfort: Naturally cooling, responsive support with no excessive sink.
- Health: No petroleum foams, no fiberglass, no chemical flame retardants.
- Cost: Queen build ≈ $520–$720 depending on sourcing (see BOM.md).
Engineering Standards
- 100% natural GOLS-certified latex (Dunlop base + Talalay comfort layer)
- High-count pocketed Marshall coils for motion isolation and airflow
- Organic wool batting as natural fire barrier
- Modular architecture for adjustable firmness and serviceability
- GOTS-certified organic cotton cover
Quick Start
1. Review BOM.md and SAFETY.md
2. Source components (see sourcing.md)
3. Cut latex sheets to specification
4. Assemble per step-by-step guide
5. Deploy sovereign sleep system
