Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The strongest reason to choose this mattress is temperature. Wool is naturally breathable, keeping you cool in summer and warmer in winter, and the Tencel™ Lyocell cover is woven to move moisture away from you as you sleep. The Platinum comfort layer offers pressure relief comparable to memory foam while being far more breathable, so hot sleepers get cushioning without the heat build-up. The wool is traceable under the British Wools scheme and the mattress uses natural flame retardants, which will matter if you're trying to avoid chemical treatments. Add the dual spring system, a 60-night trial and a 5-year guarantee, and at £494 to £734 it sits at a fair price for a wool-based pocket spring design.
Key Features & what's inside
- Tencel™ Lyocell sleep surface. A silky, soft-touch top layer woven to allow airflow and move moisture away from you, which means you're less likely to wake up clammy. It's the first thing you'll feel through your bedding.
- Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam with the same level of pressure relief. In practice that means a cocooning, cushioned feel without the warmth foam can trap.
- British Wool Comfort Layer. Wool from Cheviot sheep, flexible and breathable, helping regulate temperature so you stay cool in summer and warm in winter. It's a natural material doing a job synthetic layers often struggle with.
- Mirapocket® springs and mini pocket springs. 600 Mirapocket® springs work with 1000 mini pocket springs, which means each spring responds to your body independently for tailored support. The dual layer also increases breathability through the core of the mattress.

Who's it NOT for?
If you love the deep, slow-sinking hug of memory foam, this foam free design will feel springier and more responsive than you're used to. The medium feel suits most sleepers, although anyone wanting a firm, unyielding surface should look elsewhere. There's also no UK King size listed, only Single, Double and Super King.
Silentnight British Wool 1600 Mattress

Is the Silentnight British Wool 1600 mattress firm or soft?
It's a medium. That's a middle-of-the-road feel that suits most sleeping positions, with the wool and Platinum comfort layers adding gentle cushioning over the pocket spring support.
Does the Silentnight British Wool 1600 have memory foam in it?
No, it's certified foam free. Comfort comes from British wool, a breathable Platinum comfort layer and a Tencel™ Lyocell surface instead, which makes it a good pick if foam leaves you too warm.
How many springs does the Silentnight British Wool 1600 have?
1600 in total: 600 Mirapocket® springs combined with 1000 mini pocket springs. The mini springs add extra comfort and help air move through the mattress.
Does the Silentnight British Wool 1600 come with a trial and guarantee?
Yes. Silentnight offers a 60-night trial and a 5-year guarantee, so you have time to sleep on it properly before committing.
How deep is the Silentnight British Wool 1600 mattress?
It's 29cm deep, a fairly generous profile. Standard fitted sheets should still work, but check yours if they're on the shallow side.
