Hypnos Wool Tranquility Small Single Mattress

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.
