Layer Details
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.
