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 for two without filling the room: At 135 x 190cm it gives each of you 67.5cm, which leaves floor space for a wardrobe and drawers in bedrooms where a UK king would crowd everything.
- Less disturbance at close quarters: The pocketed springs move independently, which matters more on a UK double because you and your partner sleep closer together than on a UK king.
- Sensible when the budget is stretched: If you're kitting out a first flat and every room needs something, this gives you a sprung, layered mattress for two while leaving money for the rest.
- A kind choice for guest rooms: Visiting couples get a soft, forgiving surface that most positions find comfortable, in a UK double that still leaves the spare room usable between visits.
This size suits you if...
You share a bed in an ordinary-sized bedroom and want bedside tables on both sides, or you're setting up a spare room for couples who come to stay. It also suits a solo sleeper who likes to spread out and doesn't mind the cat taking a corner.
Consider another size if...
You both run tall or already bump elbows, and your bedroom has space to spare. We'd recommend the UK king instead; the UK double is 10cm shorter, and we suggest at least 2.7m x 2.9m for the UK king.

FAQ's
How much space does each person get on the SleepSoul Cloud 800 UK double?
Sharing the UK double gives you 67.5cm each. That's comfortable for most couples, although if one of you sprawls it can feel a little snug. The UK king gives 75cm each, so the UK double gives 7.5cm less per person.
Will the SleepSoul Cloud 800 UK double fit in a small bedroom?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m feeling comfortable once bedside tables are in. If your room is tighter, the UK small double is 15cm narrower, and we suggest at least 2.4m x 2.8m for it.
What are the SleepSoul Cloud 800 double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. The mattress is 32cm deep, so allow for that if you're checking fitted sheets or how high it will sit on your bed frame.
Is the SleepSoul Cloud 800 UK double long enough for tall people?
At 190cm long, the UK double suits most people, but if you're tall and your feet already reach the end of your current bed, look at the UK king. The UK double is 10cm shorter than the UK king.
Will I feel my partner move on a SleepSoul Cloud 800 double?
Less than on a basic open-coil mattress, because the pocket springs work independently. You will be closer together on a UK double than on a UK king, though, so light sleepers sharing with a restless partner may still notice some movement.
