Layer Details
- Reflex Foam. A 2cm layer of high-density Reflex foam sits at the top, adapting to your shape for enhanced support. It's a thin comfort layer, so expect a supportive feel rather than deep cushioning.
- Pocket Springs. Beneath the foam are 800 individual pocket springs, each moving independently for pressure relief and personalised support. Because the springs respond separately, you're less likely to feel a partner shifting about.

- Space left for the rest of the room: At 90cm wide, a UK single leaves space for a desk and wardrobe in a child's bedroom, and we suggest allowing at least 2.1m x 2.8m of floor.
- A slimmer mattress for raised frames: At 23cm deep it's slimmer than some hybrids, which helps on cabin beds and mid sleepers, although you should still check the frame maker's maximum mattress depth.
- Two beds in one guest room: A pair of UK singles lets a spare room sleep two guests who'd rather not share, with each person on their own mattress instead of one shared surface.
- Support for one sleeper: The medium firm feel suits most solo sleepers, although a light child who sleeps on their side may find it slightly firm at the shoulders and hips.
- Easy bedding: Standard single sheets and a single duvet at 135 x 200cm fit, so replacing bedding after a spill in a child's room is simple.
This size suits you if...
You sleep alone in a compact room or under a sloping loft ceiling, you're kitting out a child's or teenager's bedroom where a desk and storage also need floor space, or you want two separate beds in a guest room.
Consider another size if...
You share the bed regularly or like room to spread out. We'd recommend the UK small double instead: the UK single is 30cm narrower, and we suggest at least 2.4m x 2.8m for the UK small double.

Will the SleepSoul Comfort 800 UK single fit a bunk bed or mid sleeper?
It measures 90 x 190cm, the standard UK single footprint that most bunk and mid-sleeper frames are built around. The mattress is 23cm deep, which is slimmer than some hybrids. Raised frames usually set a maximum mattress depth so the guard rail stays effective, so check the frame maker's guidance before you buy.
What size bedroom do I need for a SleepSoul Comfort 800 single?
We suggest at least 2.1m x 2.8m for a UK single. That leaves room to walk around the bed and open drawers. In a shared children's room with two beds, you'll want more than that so there's a clear walkway between them.
Is the SleepSoul Comfort 800 UK single good for a teenager?
For a teenager sleeping alone it's a sensible fit: 90cm wide and 190cm long, with medium firm pocket-spring support. A teen who sits on the bed to game or study should know that some owners mention feeling springs at the edges, and on a mattress 3ft wide you spend more time near them.
Should I get the Comfort 800 in a UK single or UK small double?
The UK single is 30cm narrower than the UK small double, and both are the same length. If one person sleeps in it and the room is tight, the UK single makes sense. If you want space to sprawl, choose the UK small double, for which we suggest at least 2.4m x 2.8m.
Will I feel the edges on a single SleepSoul Comfort 800?
You might. Across verified owner reviews, some people mention feeling springs at the edges, and the thin 2cm foam layer does little to hide them. On a UK single you're rarely far from an edge, so if you tend to sleep right at the side, a wider size gives you more room to stay away from it.
