Layer Details
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.
