Difference compared to traditional cold foam mattresses

Many cold foam mattresses are made from petroleum-based PU foams. Tuur® uses Naturalis® cold foam, a sustainable alternative that:

  • Produces less CO₂ emissions during manufacturing
  • Is made with plant-based oil (castor plant)
  • Offers better breathability and moisture regulation than traditional cold foam
  • Does not release a chemical smell when unpacked

Frequently asked questions about cold foam mattresses

A cold foam mattress can be good for back pain, provided the right firmness is chosen. The even support across the entire surface avoids pressure points. 

• Ideal for back and stomach sleepers looking for even support
• For chronic back pain with pressure points on shoulder/hip, choose natural latex instead
• In doubt? Take the free Mattress Test for personal advice

Cold foam sleeps better for active sleepers and hot sleepers; memory foam is better for those seeking pressure relief and an enveloping feeling. 

• Hot sleeper or moves a lot -> cold foam ✓
• Sensitive pressure points, still sleeper -> memory foam
• At Tuur® we prefer cold foam and latex over memory foam: better ventilation, longer lifespan and no synthetic 'memory molecules'

Cold foam (HR foam) combines excellent ventilation, resilient support and hypoallergenicity in a lighter and more accessible mattress than natural latex. 

• Open cell structure: air and moisture flow freely - ideal for hot sleepers
• Springs back immediately after load, no 'being stuck' feeling like with memory foam
• The Tuur® Pure Mattress is made from ecologically certified cold foam (OEKO-TEX®)
