Layer Details
Cover
A soft quilted or stretch knit cover, described as a breathable knit. It's the first thing you feel, and it helps air move through the surface.
CoolGel foam
A 2cm layer of CoolGel foam within the quilting. It adds cushioning and has cooling properties, so the surface feels softer without trapping as much heat.
CoolGel foam
A second 2cm layer of CoolGel foam. Together with the first it builds the pillow top feel and gives more give under your shoulders and hips.
Memory/support foam
A 1cm layer of foam, described as memory or support foam. It sits between the gel and the springs, so the comfort layers don't feel the springs underneath.
Pocket springs
1000 individually pocketed springs in cloth sleeves, with a foundation layer beneath. Each spring moves on its own, so the mattress responds to your body and gives steady support.

Key benefits
- Fits the bedroom most couples have: At 135 x 190cm, it leaves space for bedside tables on both sides in many rooms that meet our suggested minimum of 2.6m x 2.8m.
- Springs that respond to each of you: The 1000 pocketed springs each move on their own, which means the mattress reacts to each sleeper separately rather than as one surface.
- Less trapped heat with two in the bed: Two people give off more warmth than one, and the gel foam layers and breathable knit cover help the surface hold on to less of it.
- Easier up awkward stairs: It arrives vacuum-packed and rolled in a box, so carrying a UK double round the tight turn of an older terrace staircase is far less of a struggle.
- Bedding you can find anywhere: Double sheets and duvets are sold almost everywhere, which helps if you're kitting out a whole home at once and need the bedding budget to stretch.
This size suits you if...
You share a bed with a partner in a typical UK bedroom and still want space for a wardrobe and drawers, or you sleep alone but like room to spread out, perhaps with a cat or dog settling at the foot of the bed.
Consider another size if...
You're both broad-shouldered or restless sleepers and 67.5cm each feels tight. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m for it.

FAQ's
Is the SleepSoul Heaven Gel Pocket 1000 UK double big enough for two people?
For most couples, yes. The UK double gives each of you 67.5cm, which feels comfortable if you both sleep fairly still. If one of you sprawls or you're both broad across the shoulders, it can feel snug, and the UK king, at 75cm each, would give you more breathing room.
What room size do I need for a UK double pillowtop mattress?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m being comfortable. The larger figure matters if you want bedside tables on both sides plus a wardrobe, so you can still open doors and walk round the bed without shuffling sideways.
Will a rolled UK double mattress fit up narrow stairs?
Rolled and vacuum-packed, the UK double is far easier to manoeuvre than a flat mattress, so turning stairs in older terraces and tight new build landings are rarely a problem. Check the box dimensions with the retailer before buying, then measure your narrowest turn.
Should I choose the UK double or UK king SleepSoul Heaven Gel Pocket 1000?
The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for it. If your room is close to 2.6m x 2.8m, the UK double keeps space to move around; if you have the floor area and want more room each, size up.
What size sheets and duvet fit a UK double mattress?
Standard double fitted sheets made for 135 x 190cm will fit, and a 200 x 200cm double duvet covers it well. The mattress is 25cm deep with a pillow top, so look for fitted sheets with deep enough pockets to tuck securely under the edges.
