Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're a hot sleeper, this is one of the stronger reasons to look here: wool naturally regulates temperature, keeping you cool in summer and warm in winter, and the Tencel™ Lyocell surface is woven to move moisture away from you as you sleep. The two-tier spring system, 600 Mirapocket® springs plus 1000 mini pocket springs, gives responsive support with extra breathability, so the mattress feels supportive without the sinking sensation of foam. It's also foam free with natural flame retardants, which will appeal if you prefer natural materials. The Medium firmness suits most sleepers, although those who like a very firm surface may find it slightly too forgiving. At £539 to £759 it sits at a fair price for a wool pocket sprung design.
Key Features & what's inside
- Tencel™ Lyocell sleep surface. A silky, soft-touch material woven to allow airflow, which means moisture is moved away from you rather than trapped at the surface. You should feel drier through the night as a result.
- British Wool Comfort Layer. Flexible, breathable wool from Cheviot sheep that keeps you cool in the summer and warm in the winter. It's a natural temperature regulator, doing quietly what synthetic layers often struggle with.
- Platinum comfort layer. Silentnight says this is 10x more breathable than memory foam while offering the same pressure relief. In practice that means a cocooning, cushioned feel without the heat build-up foam can bring.
- Mirapocket® springs and mini pocket springs. 600 Mirapocket® springs work alongside 1000 mini pocket springs for additional comfort and increased breathability. Pocket springs move independently, which means less disturbance when a partner shifts position.

Who's it NOT for?
If you love the deep, slow sink of memory foam, this foam-free design will feel springier and more responsive than you're used to. Sleepers who need a very firm surface may also find the Medium feel a little too soft. And, a 5-year guarantee is shorter than some brands offer.

How firm is the Silentnight British Wool 1600 Pocket Mattress?
Silentnight rates it as Medium. That suits most sleepers, including side and combination sleepers, although if you sleep on your front or prefer a noticeably firm surface you may want something with more resistance.
Does the Silentnight British Wool 1600 sleep hot?
It's designed to do the opposite. The British wool layer regulates temperature naturally, the Tencel™ Lyocell surface moves moisture away, and the pocket spring core allows air to circulate. If you're a hot sleeper, this is a sensible choice.
How many springs does the Silentnight British Wool 1600 have?
1,600 in total: 600 Mirapocket® springs combined with 1000 mini pocket springs. The mini springs add comfort and increase breathability, sitting alongside the main support springs rather than replacing them.
Does the Silentnight British Wool 1600 come with a trial and guarantee?
Yes. Silentnight's own site lists a 60-night trial and a 5-year guarantee, with delivery in 14 days. Check the terms at your chosen retailer before buying, as offers can differ between sellers.
Is the Silentnight British Wool 1600 mattress foam free?
Yes, it's certified foam free and uses natural flame retardants. The wool comes from Cheviot sheep under the British Wools traceable scheme, which will appeal if you want a mattress built around natural materials.
