The Classic 2750 comes in five sizes from UK Single to UK Super King. The fillings are natural: wool, hemp and flax, wrapped in a wool and viscose cover, which means a breathable sleep surface rather than the warmer feel of foam. At 24cm deep it sits in comfortable territory for most fitted sheets. It's handcrafted in the UK and a National Bed Federation Approved Brand, which offers some reassurance about what's actually inside it.

Why should you choose this mattress?
This one suits sleepers who want springs and natural fillings rather than memory foam. The 750 Cortec Quad springs at the core, each pocket holding four springs fused into one, give a responsive feel, so turning over takes less effort than on foam that hugs you in place. Above them sit 2,000 MicroHD springs, a layer of smaller springs that adds a gentler, more contouring surface. Wool, hemp and flax fillings breathe well, which matters if you sleep warm. The medium feel should suit most back and side sleepers, although those who like a firmer, more supportive edge to their mattress may want to look elsewhere. Mattress Online lists a 100-night trial and a 5-year guarantee.
Key features & layer details
Cover
A cover of wool and natural viscose, fibres that are soft to the touch and naturally fire retardant. That means no chemical fire-retardant treatments are needed to meet safety standards.
Comfort fillings
Multiple layers of wool, hemp and flax sit beneath the cover, which means a cosy surface feel that also breathes well. Natural fibres like these tend to sleep cooler than synthetic foams.
MicroHD springs
A layer of 2,000 MicroHD springs sits above the core spring unit. These smaller springs add responsiveness and a more contouring feel at the surface.
Support layer
Two layers of Ecotex fibres, made from recycled materials, support the spring system. A small sustainability point, and it gives the springs a stable base to work from.
Core springs
The core holds 750 Cortec Quad springs, a design where four springs are fused into a single pocket. In practice that means increased responsiveness, so the mattress reacts quickly as you shift position.

Best suited for?
Warm sleepers
The wool, hemp and flax fillings under the wool and viscose cover breathe well, so the surface sleeps cooler than a foam mattress would.
Side sleepers
A medium feel and a layer of 2,000 MicroHD springs give a gentle, contouring surface that should suit sleeping on your side.
Back sleepers
The medium feel sits on 750 Cortec Quad springs, which should give a responsive, supportive surface for lying on your back.
Combination sleepers
Four springs fused into each pocket make the mattress react quickly as you shift, so turning over takes less effort than on hugging foam.
Eco-conscious buyers
Natural wool, hemp and flax fillings, plus a support layer of Ecotex fibres made from recycled materials, keep the build natural without chemical fire-retardant treatments.
If you like the slow, cradling sink of memory foam, this all-spring design will feel too lively. Those who want a firm mattress should look elsewhere too, as this is a medium feel. And budget shoppers may find the starting price a stretch, one that reflects the natural fillings.
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.
