Silentnight British Wool 1600 Mattress - UK King

• Tencel™ Lyocell sleep surface. A silky, soft-touch top layer woven to allow airflow and move moisture away from you, which means you're less likely to wake up clammy. It's the first thing you'll feel through your bedding.
• Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam with the same level of pressure relief. In practice that means a cocooning, cushioned feel without the warmth foam can trap.
• British Wool Comfort Layer. Wool from Cheviot sheep, flexible and breathable, helping regulate temperature so you stay cool in summer and warm in winter. It's a natural material doing a job synthetic layers often struggle with.
• Mirapocket® springs and mini pocket springs. 600 Mirapocket® springs work with 1000 mini pocket springs, which means each spring responds to your body independently for tailored support. The dual layer also increases breathability through the core of the mattress.
