Hypnos Ultimate Ortho Mattress - EU King

• Cover. A 100% viscose, chemical-free cover that feels silky against the skin. It's breathable too, which helps air move away from your body overnight.
• Comfort fillings. Natural cotton is combined with Solotex, a recycled fibre. The cotton regulates temperature while the Solotex adds resilience, so the comfort layer keeps its shape rather than flattening quickly.
• Support system. Hypnos's ReActive 6-turn pocket spring system, engineered for total spinal and body support. Each spring works independently, sensing your comfort and support requirements, which means less roll-together and more even pressure relief.
