Why should you choose this mattress?
The pillow top with micro springs gives the surface a softer, cushioned feel, while the pocket springs underneath provide responsive support that runs right to the edges. That means you can use the whole bed without feeling you might slide off. Two layers of graphite-infused memory foam help draw heat away from your body, and the Breeze cover is up to 40% more breathable than standard fabrics. It should suit most back and side sleepers who like a medium feel, although anyone wanting a very firm surface may find it too cushioned. At 35cm deep, it's also a substantial mattress.

Best suited for?
Side sleepers
The plush pillow top with micro springs gives a softer, cushioned surface, which means the medium feel has some give for shoulders and hips.
Back sleepers
Pocket springs underneath give responsive support, so a medium-rated mattress with a cushioned top suits anyone who likes comfort without a flat, hard feel.
Warm sleepers
Two layers of graphite memory foam help draw heat away from the body, and the Breeze cover is up to 40% more breathable than standard fabrics.
Couples
Edge-to-edge support from the individually wrapped pocket springs means both people can use the whole bed without feeling they might slide off.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium, and the pillow top makes the surface feel softer still. Sleepers who want a flat, very firm feel may find it too cushioned. At 35cm deep, it may also sit high on a bed frame with a tall headboard or sides.
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.
