Hypnos Imperial Ortho Supreme Mattress - EU Double

• Cover. An unbleached cotton cover that achieves fire resistance without FR chemicals, which means a cleaner, fresher sleep surface. It feels natural rather than synthetic against your bedding.
• eOlus™ Fibres. Resilient eOlus fibres sit just beneath the cover, offering body support while letting air and moisture pass through easily. In practice, that means less heat building up around you overnight.
• RWS Certified British Wool. Layers of British wool, certified by the Responsible Wool Standard, cushion your whole body so you dip into the surface just the right amount. Wool also insulates naturally, keeping you warmer in winter.
• Sustainably Sourced Cotton. Responsibly sourced cotton wicks away excess moisture, which means the surface stays feeling fresh through the night. It works alongside the wool to regulate temperature all year round.
• ReActive™ 7-Turn Pocket Springs. A support unit of ReActive 7-turn pocket springs, each moving independently to align your spine as you change position. That translates to targeted support at your hips and shoulders rather than a one-feel-fits-all base.
