Layer Details
Pillow-top layer
A 4cm layer of plush filling that sits on top of the mattress. It adds a soft, cushioned surface, so the first feel is gentle rather than firm.
Memory foam
A 3.5cm memory foam transition layer. It lets you sink in comfortably while keeping movement to a minimum, which helps if you share a bed.
Soft foam
A 1cm layer of soft foam that spreads your weight evenly. That gives deep comfort before you reach the springs below.
Pocket and mini springs
800 pocket springs plus 1200 mini springs sit beneath the foam layers. They give the springy support under the soft, cushioned top.

Key benefits
- Distance from a restless partner: You each get 90cm of width, which means a partner who twists and turns all night is simply further away than on any smaller size of this mattress.
- Room when the children wander in: When a child climbs in at 3am, 180cm of width means the two adults still keep a usable share of the bed rather than clinging to the edges.
- Space for dogs as a matter of routine: If a large dog sleeps on the bed every night, the extra width gives it somewhere to settle without taking over your side.
- Wide enough to suit a big room: In a generous period bedroom or large master, the UK super king fills the space in proportion, where a UK king can look slightly undersized against the wall.
- Same length as the UK king: The UK super king is the same length as the UK king, so taller sleepers gain width here, not extra legroom.
This size suits you if...
You share with a genuinely restless partner and want real distance between you, or children and dogs regularly end up in bed with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under our suggested 3m x 2.9m, or the door swing leaves little space around the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much wider is the SleepSoul Bliss Memory Pocket 2000 super king than the king?
The UK super king is 30cm wider than the UK king, and the two sizes are the same length. For a couple, that works out at 15cm more each: 90cm per person on the UK super king against 75cm on the UK king. The UK king needs less floor space, and we suggest at least 2.7m x 2.9m for it.
Is a UK super king big enough for two adults and a child?
For a child who comes in partway through the night, yes, a UK super king gives the most room of any size in this range. Two adults start with 90cm each, so a small child in the middle takes space from both sides without pushing either of you right to the edge. Nightly co-sleeping with an older child will still feel snug.
Super king or double for a couple with a restless sleeper?
The UK super king gives 22.5cm more each than the UK double, which offers 67.5cm per person. When one of you tosses and turns a lot, extra distance tends to help more than softer or firmer padding. SleepSoul doesn't publish details on how well this mattress limits movement, so the extra width is the more reliable fix.
Will a UK super king fit in a loft conversion bedroom?
It can, although the sloping ceiling usually decides which wall the bed goes against, and at 180cm wide a UK super king leaves less room to walk around it. Measure the floor area with full standing height, then compare it with our suggested minimum of 3m x 2.9m before you choose this size.
What should I measure before ordering a super king mattress?
Check the room against our suggested 3m x 2.9m, then check how far the bedroom door swings in and whether wardrobe doors can still open once the bed is in place. Budget for UK super king sheets and a 260 x 220cm duvet too, because bedding for a UK king won't fit.
