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 a genuinely restless partner: With 90cm each, a partner who kicks and turns is physically further away, and the independent pocket springs soften whatever movement still reaches your side.
- A share for everyone when children join you: When a small child climbs in overnight, the UK super king leaves the adults a usable strip each rather than a thin edge to cling to.
- Space for dogs who sleep on the bed: If a large dog settles at the foot or between you every night, the extra 30cm over the UK king is where that dog ends up lying.
- Soft top across a wide surface: The pillow top and memory foam cushion hips and shoulders wherever you drift, which suits side sleepers who roam across a bed this wide.
- Proportioned for a large room: In a big master bedroom or a period room with high ceilings, a 6ft x 6ft 6in bed looks in scale where a UK king can seem a little lost.
This size suits you if...
You share the bed with a partner whose tossing and turning keeps waking you, children or a large dog regularly end up sleeping with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or the extra width would leave you squeezing past the bed. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the SleepSoul Cloud 800 super king big enough for two adults and a child?
For occasional visits, yes. The UK super king gives 90cm each to two adults, so a small child tucked between you still leaves both of you some room. Bear in mind that memory foam can hold warmth, and three bodies in one bed add to that, so light bedding helps on those nights.
How much wider is the Cloud 800 super king than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length. Shared between two people, that is 15cm more each. If your main complaint is being disturbed by a partner rather than running out of legroom, width is exactly what the UK super king adds.
Does the SleepSoul Cloud 800 super king have 800 springs?
The 800 spring figure is quoted for the UK king. The retailer listing doesn't give a separate count for the UK super king, so if the exact spring count matters to you, check with the retailer before you buy. The pocketed construction and medium feel are the same across sizes.
Will the Cloud 800 super king stop a restless partner waking me?
It gives you the best chance this mattress offers. Distance does most of the work: at 90cm each, your partner's movements start further from you. The pocket springs move independently as well, so less of what does travel across reaches your side. Very light sleepers may still notice big rolls.
Will a super king Cloud 800 fit in a loft conversion bedroom?
It depends on the floor area at full head height. Allow at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. In an attic room, the sloping ceiling usually decides which wall the headboard goes against, so measure there first. A 32cm deep mattress also sits higher towards a low slope.
