Silentnight British Wool 2400 Mattress - UK King

• Tencel™ Lyocell sleep surface. A silky, soft-touch cover woven to allow airflow, which means moisture is drawn away from you as you sleep. It's a small detail that helps if you tend to wake up warm.
• Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam with the same pressure relief. In practice, that means a cocooning feel without the heat build-up foam is known for.
• British Wool comfort layer. Wool from Cheviot sheep, flexible and breathable, keeping you cool in summer and warm in winter. It's also part of a traceable British wool scheme.
• Mirapocket® springs and mini pocket springs. 1400 Mirapocket® springs adjust to your movements through the night, so you get support where your body needs it. A further 1000 mini pocket springs sit alongside for extra comfort and breathability.
