Layer Details
- Pillow Top. An extra layer of plush fillings sewn onto the surface, which means a softer, more cushioned first impression when you lie down. It gives the medium firm core a gentler feel on pressure points like hips and shoulders.
- Cool Gel Memory Foam. This foam contours to your body for pressure relief and support, while the gel helps regulate body temperature better than standard memory foam. In practice, you get the hug of memory foam with less of the heat build-up.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your body shape rather than pushing back as one unit. That independence also helps reduce disturbance when a partner moves.

- A full 90cm each: Two people sharing get 90cm each, which means a restless partner can turn over without their elbow landing on your side.
- Distance plus independent springs: Pocket springs move individually to limit motion transfer, and at this width there is also more physical gap between you, so the two effects add together.
- Space for a small visitor: When a child wanders in at 3am, the UK super king leaves room for them without either adult ending up clinging to the edge.
- More room than a UK king: The UK super king is 30cm wider than the UK king at the same length, giving each of you 15cm more space.
- In proportion in a large room: In a big master bedroom or a high-ceilinged period room, a 6ft-wide pillow-top bed fills the space properly rather than looking lost.
- Room for a large dog: If a large dog sleeps on the bed as a matter of routine, the extra width means you both keep a proper share of the mattress.
This size suits you if...
You share the bed with someone who fidgets, kicks or gets up at odd hours, and you want real distance between you. It also suits you if young children or a large dog regularly end up in the bed, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or you sleep alone. For a couple in a tighter room, we'd recommend the UK king instead, and we suggest allowing at least 2.7m x 2.9m for it.

Is the SleepSoul Wish 3000 UK super king big enough for two adults and a child?
For occasional night-time visits, yes. Two adults get 90cm each on the UK super king, so a small child can fit between you without anyone being pushed to the edge. The pocket springs move independently, which helps keep a wriggling child's movement from travelling across the whole bed.
Should I get the Wish 3000 in a UK super king or a UK king?
The UK super king is 30cm wider than the UK king and the same length, which gives each of you 15cm more space. If you share with a restless partner, that extra 15cm is where the difference shows. The trade-off is room size: we suggest at least 3m x 2.9m for the UK super king and 2.7m x 2.9m for the UK king.
Will a UK super king Wish 3000 fit in a loft conversion bedroom?
Only if the floor area clears our suggested minimum of 3m x 2.9m, and even then, the slope of the ceiling usually decides which wall the bed goes against. With a 30cm deep mattress and a pillow top, check the headroom when you sit up on the low side before you commit to the UK super king.
Does the Wish 3000 super king stop a restless partner waking me up?
It helps in two ways. You get 90cm each on the UK super king, so there is simply more distance between you, and the pocket springs respond individually rather than moving as one unit. A very restless sleeper may still be noticeable, but the extra width is usually the bigger help of the two.
Is a UK super king Wish 3000 comfortable with a large dog on the bed?
It is the most practical size for this. At 180 x 200cm, a large dog can settle at the foot or to one side while two adults keep usable space. Yes, the plush pillow top will pick up hair and paw marks, but a mattress protector sized for a UK super king handles that easily.
