Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Temperature is the strongest reason to shortlist this mattress. The Tencel™ Lyocell surface is woven to move moisture away from you, which means less of that clammy feeling on warm nights, and the British wool layer works both ways, keeping you cooler in summer and warmer in winter. The spring system is generous too: 1200 Mirapocket® springs adjust to your movements, while 1000 mini pocket springs add comfort and improve airflow through the mattress. Silentnight backs it with a 60-night trial and a 5-year guarantee, and delivery is quoted at 14 days. Across verified feed data, it carries a 4.8 rating at Mattress Online, from a single retailer listing.
Key Features & what's inside
- Tencel™ Lyocell sleep surface. A silky, soft-touch sleep surface woven to allow airflow and move moisture away from you as you sleep. In practice, that means a drier, fresher feel through the night.
- Platinum comfort layer. Silentnight describes this as 10x more breathable than memory foam with the same amount of pressure relief. You get that cocooning, cushioned feel without the heat build-up memory foam is known for.
- British Wool Comfort Layer. Wool from Cheviot sheep, chosen because it's flexible and breathable. It helps regulate temperature in both directions, keeping you cool in summer and warm in winter.
- Springs. 1200 Mirapocket® springs adjust to your movements throughout the night, so support follows you as you change position. A further 1000 mini pocket springs sit alongside them for additional comfort and increased breathability.
- Natural flame retardants. The mattress is foam free in its construction claims and uses natural flame retardants rather than chemical treatments. A reassuring detail if you're trying to keep synthetic materials to a minimum.

Who's it NOT for?
If you sleep on your side and are on the lighter side, a medium feel may sit slightly firmer than you'd like. It's also only available in UK Super King as far as we can see, so anyone with a smaller bed frame will need to look elsewhere. Budget shoppers may find £854 hard to justify.

Is the Silentnight British Wool 2200 mattress firm or soft?
Silentnight rates it as medium, which suits most back and combination sleepers, although lightweight side sleepers may find it a little too firm for deep pressure relief at the shoulder and hip.
How many springs does the Silentnight British Wool 2200 have?
2200 in total: 1200 Mirapocket® springs that adjust to your movements through the night, plus 1000 mini pocket springs that add comfort and improve breathability through the mattress.
Does the Silentnight British Wool 2200 have a trial period?
Yes. Silentnight offers a 60-night trial, so you can sleep on it at home before committing fully. It also comes with a 5-year guarantee from Silentnight.
Is the Silentnight British Wool 2200 good for hot sleepers?
It's one of its main strengths. The Tencel™ Lyocell surface moves moisture away from you, the wool layer regulates temperature, and the comfort layer is described as 10x more breathable than memory foam. The mini pocket springs add airflow too.
How deep is the Silentnight British Wool 2200 mattress?
It's 29cm deep, which means standard fitted sheets should still work, though it's worth checking your sheets are rated for deeper mattresses before it arrives.
