Hypnos Wool Tranquility Mattress - UK Emperor

• Viscose Blend Breathable Sleep Surface. A soft viscose blend cover that promotes airflow, which means the sleep surface stays cooler and fresher through the night.
• Sustainably Sourced British Wool. British wool gives gentle cushioning with impressive resilience. In practice that means a comfort layer that keeps its shape rather than developing body impressions quickly.
• Sustainably Sourced Cotton. Natural cotton fibres are highly breathable and wick away excess moisture. You'll feel this as a cooler, drier surface, particularly useful if you tend to overheat.
• eOlus™ Fibres. These fibres offer a soft, foam-like feel while letting air and moisture pass through easily. You get the comfort of foam without the heat retention it's often criticised for.
• ReActive™ 8-Turn Pocket Springs. The base is 1400 individually responsive pocket springs, each with 8 turns, engineered for total spinal and body support. Each spring senses and adjusts independently, so movement on one side of the bed is less likely to disturb the other.
