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
- Leaves floor space free: At 3ft x 6ft 3in, the UK single sits along one wall and still leaves space for a wardrobe, toy storage or a desk in a small bedroom.
- Two beds in a shared room: Two UK singles can sit side by side with a walkway between them, which suits siblings sharing a room or a guest room for two.
- Cushioning for lighter sleepers: The pillow top and gel foam layers give a little more give than the medium rating suggests, which most children and lighter adults will find comfortable.
- Cooler for warm rooms: The CoolGel foam and breathable knit cover help release heat, which is useful in a stuffy loft conversion or a small room with the door shut.
- Easier to carry up narrow stairs: It comes rolled and vacuum-packed in a box, so you can carry it up a tight staircase or into a loft conversion with a single-width frame.
- Simple bedding: Standard single sheets and a single duvet (135 x 200cm) fit, although you'll want fitted sheets with enough depth for its 25cm profile.
This size suits you if...
You sleep alone in a compact bedroom, you're furnishing a child's or teenager's room where storage and a desk compete for space, or you're setting up a spare room with two singles so guests don't have to share.
Consider another size if...
You share the bed, or you're a solo adult who sprawls and has the space. The UK small double would suit you better: it's 30cm wider, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the SleepSoul Heaven Gel Pocket 1000 UK single fit a bunk bed or mid sleeper?
The width and length match a standard UK single frame, so the footprint will fit. Depth is the thing to check: the mattress is 25cm deep, and raised frames often set a maximum mattress depth so the safety rail stays high enough. Look at the frame maker's guidance before you order.
How much bedroom space do I need for a UK single SleepSoul Heaven mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers, and it's why this size fits box rooms, studies and small children's bedrooms where a UK small double would feel cramped.
Is a UK single SleepSoul Heaven Gel Pocket 1000 long enough for a tall teenager?
It's 190cm long, the same length as the UK small double and UK double. A tall teenager or adult who wants more legroom would need the UK king, which is 10cm longer, but that means a much wider bed and a bigger room.
Can I put two SleepSoul Heaven single mattresses in a guest room?
Yes, and plenty of people do, because two guests who aren't a couple can each have their own bed. Two UK singles side by side with a gap between them take up more width than one, so measure the wall and leave a walkway before you buy both.
What size sheets and duvet fit the SleepSoul Heaven single?
Standard UK single fitted sheets and a single duvet at 135 x 200cm will fit. Because the mattress is 25cm deep with a pillow top, choose fitted sheets described as deep or extra deep so the corners stay tucked under rather than pinging off overnight.
