Why should you choose this mattress?
The 2cm pillow top gives the surface a softer feel, while the medium to firm rating means the support underneath stays fairly firm. The 3cm Cool Gel foam layer contours to your body and is there for heat dispersal, so it should help if you sleep warm. SleepSoul says the mini pocket springs reduce motion transfer, which helps if a partner moves in the night. The knitted cover is breathable. It suits most back and combination sleepers, although very light side sleepers may want more give.
Key features & layer details
Pillow top
A 2cm layer of soft foam in the microquilted surface. It gives the top a softer, more cushioned feel without changing the medium to firm rating.
Cool Gel foam
A 3cm Cool Gel foam layer under the pillow top that contours to the body. It also helps disperse heat, so you get shaping with less warmth.
Pocket spring core
1000 individually pocketed springs, with 2000 mini pocket springs added for bounce and comfort. The mini springs reduce motion transfer, so you're less likely to feel a partner move.

Best suited for?
Back sleepers
The medium to firm rating keeps the support underneath fairly firm, while the 2cm pillow top adds a softer, cushioned feel on the surface.
Combination sleepers
A medium to firm feel with a cushioned pillow top suits changing positions through the night, and the mini pocket springs add bounce and comfort.
Warm sleepers
The 3cm Cool Gel foam layer is there for heat dispersal, and the breathable knitted cover means you get body shaping with less warmth.
Couples
The mini pocket springs reduce motion transfer, which means you are less likely to feel your partner move during the night.
If you prefer sleeping on a very soft mattress, this might not be the best choice. It's rated medium to firm, and the pillow top softens the surface without changing that rating. It can't be flipped, so you're limited to turning it with the handles. Check stock on the UK king and UK super king before you order.
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.
