Silentnight British Wool 1800 Mattress - UK King

• Breathable Tencel™ Lyocell sleep surface. A silky, soft-touch material woven to allow airflow and move moisture away from you as you sleep. The result is a naturally cool feel when you first lie down.
• British Wool Comfort Layer. Wool sourced from Cheviot sheep, chosen because it's flexible and breathable. It helps keep you cool in summer and warm in winter, which means fewer temperature-related wake-ups year round.
• Platinum comfort layer. Silentnight says this layer is 10x more breathable than memory foam while offering the same pressure relief. In practice that means a cocooning, cushioned feel without the heat build-up memory foam is known for.
• 800 Mirapocket® springs plus 1000 mini springs. The 800 Mirapocket® springs adjust to your movements through the night, giving tailored support that follows your body shape. The 1000 mini pocket springs sit alongside for extra comfort and increased breathability.
