FAQ
A cold foam (HR foam) mattress is made from high-resilience polyurethane with an open-cell structure, known for its excellent ventilation, durability, and support. The Tuur® Pure Mattress uses Naturalis® cold foam, which is made from castor oil instead of petroleum-based chemicals.
Most conventional cold foams are fully synthetic. Naturalis® cold foam offers the same elasticity and resilience but is:
- Plant-based (castor oil)
- Free from harmful chemicals
- Odorless at first use
It’s a cleaner, more sustainable alternative to standard HR foams.
With 7 ergonomic comfort zones, it’s perfect for:
- Back sleepers (lumbar support)
- Side sleepers (shoulder/hip relief)
- Stomach sleepers (spinal alignment)
Naturalis® foam is dense and durable. The average lifespan is around 10 years, with minimal sagging and consistent support throughout its use.
Yes. Cold foam is flexible, making it ideal for use with electric or manual adjustable bases.
No. Thanks to the natural composition of Naturalis® foam, the mattress is odorless and ready to use right after unpacking. No off-gassing or airing out required.
