Why should you choose this mattress?
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, it's a real investment, but the 60-night trial and 5-year guarantee give you a safety net while you decide.
Key features & layer details
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.

Best suited for?
Warm sleepers
Breathable wool and a Tencel™ Lyocell surface that moves moisture away from you mean heat is less likely to build up overnight.
Eco-conscious buyers
Silentnight states this mattress is foam free, with natural flame retardants and a British wool comfort layer, so it avoids synthetic foams.
Side sleepers
The Platinum comfort layer is said to give the same pressure relief as memory foam, so shoulders and hips should feel cushioned.
Combination sleepers
Mirapocket® springs adjust to your movements through the night, which means support stays consistent as you shift between positions.
Couples
Individually pocketed springs, plus a range of sizes up to Super King, give two people room to settle and move independently.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
