Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you sleep warm, this is the standout reason to consider it. Wool is naturally breathable, keeping you cool in summer and warm in winter, and the Tencel™ Lyocell surface moves moisture away from you rather than trapping it. Silentnight also states the mattress is foam free and uses natural flame retardants, which will appeal if you'd rather avoid synthetic foams. Support comes from 1,200 Mirapocket® springs that adjust to your movements, plus 1,000 mini pocket springs for extra comfort and airflow. Yes, £639 to £879 is a real investment, but the 60-night trial and 5-year guarantee give you a safety net while you decide.
Key Features & what's inside
- Tencel™ Lyocell sleep surface. A silky, soft-touch material woven to allow airflow, which means heat is less likely to build up where your body meets the mattress. It also moves moisture away from you as you sleep.
- Platinum comfort layer. Silentnight says this layer is 10x more breathable than memory foam while offering the same pressure relief. In practice that should mean a cocooning, cushioned feel without the warmth memory foam is known for.
- British Wool Comfort Layer. Wool from Cheviot sheep, a flexible and breathable material that helps keep you cool in summer and warm in winter. It's the natural heart of this mattress.
- Mirapocket® springs and mini pocket springs. 1,200 Mirapocket® springs adjust to your movements through the night, which means support stays consistent as you shift position. A further 1,000 mini pocket springs add comfort and increase breathability.

Who's it NOT for?
If you prefer a firm mattress, this medium feel may sink a little more than you'd like, particularly for heavier back and stomach sleepers who need extra pushback. And if memory foam's slow, hugging sink is what you love, this foam-free build will feel noticeably springier by comparison.
