Why should you choose this mattress?
The pillow top and tufted surface give a soft, cushioned feel, which suits side sleepers and lighter sleepers who want some give. Underneath, the springs are arranged in three layers, so the softness sits on a more structured base rather than on foam alone. The fillings include British wool, cotton, hemp and flax, a good choice if you prefer natural materials. It also has a reinforced edge and turning handles, which makes it easier to move and rotate. Overall it suits most sleepers who like a soft to medium feel, although heavier sleepers may want something firmer.
Key features & layer details
Pillow top
A tufted pillow top surface. It gives the mattress its soft, cushioned feel when you first lie down.
Comfort fillings
A layer of British wool plus a blend of cotton, hemp and flax fibres. These natural fillings add softness and give the mattress a natural-fibre feel.
High density pocket springs
2500 high density pocket springs form the top spring layer. They sit directly under the fillings and give the first layer of spring support.
Posturfil pocket springs
1000 Posturfil pocket springs sit below the high density layer. They add a second level of support beneath the softer top.
Cortec pocket springs
Cortec pocket springs form the base of the spring system, with a polyester pad on each side. They finish the three-layer spring build that the softer layers rest on.

Best suited for?
Side sleepers
The tufted pillow top and medium soft rating give a cushioned surface with some give, which suits the way side sleeping asks the mattress to soften around the body.
Lighter sleepers
A pillow top and natural fillings of British wool, cotton, hemp and flax give a soft surface with plenty of give for lighter frames.
Eco-conscious buyers
Comfort layers made from British wool plus a blend of cotton, hemp and flax fibres mean the soft feel comes from natural materials rather than foam.
Combination sleepers
Three layers of pocket springs sit beneath the soft top, so the cushioning rests on a more structured base that supports changes of position.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium soft, and the pillow top adds extra cushioning. Heavier sleepers and front sleepers who need firmer support may find it too yielding. It can't be flipped, so you're limited to rotating it, and at 28cm deep it needs a frame that suits that height.
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.
