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 to spread out alone: The UK small double is 30cm wider than the UK single, which means you can sleep diagonally or starfish without an arm hanging off the edge.
- Keeps small rooms usable: Being 15cm narrower than the UK double can decide whether a wardrobe door still opens or you can walk past the bed without turning sideways.
- Same length as a double: The UK small double matches the UK double for length, so you lose only width by choosing it, and adults of average height won't find their feet overhanging.
- Soft top suits solo side sleeping: The plush pillow top and memory foam cushion shoulders and hips, which suits someone sleeping alone on their side who can use the full width to shift position.
- Fine for the occasional couple: Independently moving pocket springs mean one person turning over disturbs the other a little less, which helps on the nights a partner or guest shares.
This size suits you if...
You sleep alone most nights and feel cramped on a single, your bedroom is a box room, studio or loft conversion that can't take a full double, or you want a guest bed that two people can share for a weekend without anyone sleeping there every night.
Consider another size if...
You share the bed every night and want room of your own. We'd recommend the UK double instead: it gives 67.5cm each, and we suggest at least 2.6m x 2.8m for it.

FAQ's
Is the SleepSoul Cloud 800 small double big enough for a couple?
For occasional nights, yes, although it will feel close. For nightly sharing, the UK double would suit you better, giving 67.5cm each. We suggest at least 2.6m x 2.8m of floor space for the UK double, so measure before you size up.
What size room do I need for a SleepSoul Cloud 800 small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk around the bed and open drawers. If your room is tighter than that, the UK single needs at least 2.1m x 2.8m by our guidance.
How much wider is a small double SleepSoul Cloud 800 than a single?
The UK small double is 30cm wider than the UK single, and both are the same length. So the upgrade gives you more room side to side without a longer bed, which helps a teenager or adult who has outgrown a single but can't give up much floor space.
Is a 4ft SleepSoul Cloud 800 long enough for a tall person?
The UK small double is 190cm long, the same as the UK single and UK double. If you're tall and your feet reach the end, the UK king is 10cm longer. We suggest at least 2.7m x 2.9m for the UK king, so check your room first.
Will the SleepSoul Cloud 800 small double fit in a loft conversion?
Often, yes. The narrower 120cm width helps where a sloping ceiling leaves little standing room beside the bed. Measure the usable floor, not the whole room, against our suggested 2.4m x 2.8m. The mattress is 32cm deep, so allow for that plus your frame height under the slope.
