Silentnight British Wool 2200 Mattress - UK King

• Tencel™ Lyocell sleep surface. A silky, soft-touch sleep surface woven to allow airflow and move moisture away from you as you sleep. In practice, that means a drier, fresher feel through the night.
• Platinum comfort layer. Silentnight describes this as 10x more breathable than memory foam with the same amount of pressure relief. You get that cocooning, cushioned feel without the heat build-up memory foam is known for.
• British Wool Comfort Layer. Wool from Cheviot sheep, chosen because it's flexible and breathable. It helps regulate temperature in both directions, keeping you cool in summer and warm in winter.
• Springs. 1200 Mirapocket® springs adjust to your movements throughout the night, so support follows you as you change position. A further 1000 mini pocket springs sit alongside them for additional comfort and increased breathability.
• Natural flame retardants. The mattress is foam free in its construction claims and uses natural flame retardants rather than chemical treatments. A reassuring detail if you're trying to keep synthetic materials to a minimum.
