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
- Room to sprawl on your own: The UK small double is 30cm wider than the UK single, which means a solo sleeper can turn over or stretch an arm out without hitting the edge.
- Fits rooms a double would crowd: Being 15cm narrower than the UK double, it can leave enough floor for a door to swing open or a bedside table to sit beside it.
- Cushioning in a narrower bed: Two 2cm CoolGel foam layers form the pillow top, so one sleeper gets give under the shoulders and hips across the whole 120cm width.
- Easier into awkward rooms: It comes vacuum-packed and rolled, which helps when the route is a narrow loft staircase or a tight turn on a landing.
- Cooler for warm sleepers: If you run hot, the gel foam and breathable knitted cover help keep heat from building up on the pillow top.
This size suits you if...
You sleep alone and want more width than a single, your bedroom is too compact to take a standard double comfortably, or you're kitting out a guest room where a couple stays now and then but nobody sleeps every night.
Consider another size if...
You share a bed every night and want room to move. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the SleepSoul Heaven Gel Pocket 1000 UK small double big enough for two?
For occasional stays, yes, and it suits a guest room where couples visit now and then. For nightly sharing it's tight, with little spare width for either of you to turn over freely. If two of you sleep in it every night, the UK double gives 67.5cm each and is 15cm wider.
What size room do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves room to walk around the bed and open a door. In a box room or a small rental second bedroom, measure from the wall to where the door swings before buying, because the width usually decides whether it clears.
Should a teenager move from a single to a UK small double?
If they've outgrown a single and sprawl at night, the UK small double is a sensible step. It's 30cm wider than the UK single at the same length, so it takes less floor space than a full double. A UK single needs at least 2.1m x 2.8m, against 2.4m x 2.8m for the small double.
Is the SleepSoul Heaven UK small double long enough if I'm tall?
The UK small double is 190cm long, or 6ft 3in, the same length as the UK single and UK double. If your feet already reach the end of your current bed, the UK king is 10cm longer, although it's also 30cm wider and we suggest at least 2.7m x 2.9m for it.
What bedding fits a SleepSoul Heaven Gel Pocket 1000 small double?
Use small double (4ft) fitted sheets with a standard double duvet, which gives a little extra overhang on each side. The mattress is 25cm deep with a pillow top, so check the fitted sheet's pocket depth before you buy, and look at the retailers listed on this page for matching options.
