Layer Details
Pillow Top
An extra layer of plush filling sewn onto the surface, which means a soft, cushioned feel the moment you lie down. It's the layer that gives the mattress its cloud-like first impression.
Memory Foam
Memory foam moulds to your body, which means pressure points like hips and shoulders get cradled rather than pushed against. It also adds a supportive, contouring quality beneath the softer top.
Pocket Springs
The King size contains 800 individually pocketed springs, each in its own fabric pocket so they move independently. In practice that means better motion isolation and support that responds to where you actually need it.

Key benefits
- Room left for everything else: At 90cm wide the UK single leaves space for a wardrobe, desk and toy storage, and we suggest allowing at least 2.1m x 2.8m of floor.
- A softer surface for one: The pillow top and memory foam give a cushioned, contouring feel, which means a lighter child or side-sleeping teen sinks in comfortably rather than lying on top.
- Two can sit side by side: In a spare room, a pair of UK singles gives two guests a bed each, a friendlier setup for friends or siblings than one shared UK double.
- Fits under a sloping ceiling: The narrow 3ft footprint can tuck lengthways beneath the slope of a loft conversion, where a wider bed would push into the lowest part of the ceiling.
- Easy to live with: It's hypoallergenic and vegan friendly, and standard single sheets and a single duvet fit, so kitting out a child's or guest bed stays simple.
This size suits you if...
You're buying for a child or teenager who has moved on from a basic foam mattress, you sleep alone in a compact room or loft conversion, or you're furnishing a guest room where two separate beds make more sense than one.
Consider another size if...
You share the bed, or you're a tall or restless adult who wants room to spread out. We'd recommend the UK small double instead, which is 30cm wider; we suggest at least 2.4m x 2.8m for it.

FAQ's
Is the SleepSoul Cloud 800 UK single too deep for a bunk bed?
Possibly. The Cloud 800 is 32cm deep, which is thick for a raised frame. Bunk beds, cabin beds and mid sleepers usually set a maximum mattress depth so the guard rail stays high enough above the sleeping surface. Check your frame maker's figure before ordering; on a standard divan or bedstead the depth is no problem.
Is the Cloud 800 in a UK single good for a child's bedroom?
For many children, yes. The medium feel with a soft pillow top suits lighter bodies, and it's hypoallergenic. The downside is warmth: memory foam can hold heat, so a child who kicks the covers off every night may sleep cooler on something more breathable. Allow at least 2.1m x 2.8m of floor space for the UK single.
Will a UK single Cloud 800 fit in a small bedroom or loft room?
The UK single measures 90 x 190cm, or 3ft x 6ft 3in, and we suggest a room of at least 2.1m x 2.8m. In a loft conversion, run the bed lengthways under the slope so you have headroom to sit up. The 32cm depth raises the surface a little, so check the ceiling height over the pillow end.
Should I get the Cloud 800 in a UK single or a UK small double for a teenager?
If the room is tight, the UK single keeps floor space for a desk. If your teenager is growing fast or sprawls, the UK small double is 30cm wider and the same length, and we suggest at least 2.4m x 2.8m for it. Both sizes share the same medium, cushioned feel.
Are two SleepSoul Cloud 800 singles better than a double for a guest room?
For guests who won't share, usually yes. Two UK singles give each person their own surface, and siblings or friends can sleep without disturbing each other. You'll need a wider room than for one bed, plus a walkway between them. A couple visiting would find the UK double more comfortable, which gives 67.5cm each for two sharing.
