Assessed from the specification published by MattressNextDay, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is natural materials at a mid-range price. The comfort layers blend sustainably sourced British wool with silk, which means good insulation and breathability rather than the heat build-up you can get with foam. Underneath, 1,500 pocket springs move independently of one another, so the mattress responds to your body shape and you feel less of a partner's movement. Relyon is an NBF-approved manufacturer and the mattress meets the BS7177: 2008 fire safety standard for domestic use, with hypoallergenic fillings. MattressNextDay lists a 10-year guarantee and free next day delivery to mainland UK, though some addresses may incur a small fee. There is no memory foam contouring here, but many sleepers prefer the springier, more traditional feel.
Key Features & what's inside
- Cover. A Belgian Damask viscose sleep surface, which means a silky soft feel against bedding. It is highly breathable, helping to create a fresher sleeping environment.
- Comfort Fillings. A naturally soft, lightweight blend of British wool and silk. These fibres offer excellent insulation, which means they help keep you cool in summer and warm in winter.
- Support System. 1,500 pocket springs, each mounted in its own separate fabric pocket. Because the springs work completely independently, they follow your body shape more closely and relieve pressure where you need it.

Who's it NOT for?
If you like a soft, sink-in feel, this medium firm build will probably feel too solid. Anyone wanting the slow, moulding hug of memory foam should look elsewhere, as the comfort here comes from wool, silk and springs. It is also unsuitable if you need a small double or EU size.
