Layer Details
Pillow top
A generous pillow top sits at the surface and adds an extra layer of cushioning. It gives you a softer feel to sink into, though you can rotate this mattress but not flip it.
Pocket spring core
The core has 1,000 individually pocketed springs that respond independently to your body's shape. That means support that follows your outline, and less movement travelling across the bed if you share it.
Wool and silk layer
Inside, a blend of natural wool and silk sits alongside deep comfort layers of cotton and soft white fibres. These natural fillings add softness and padding between the surface and the springs.

Key benefits
- Room to spread out: At 90cm each for two sharing, you each get a sleeping space as wide as a UK single, so elbows and knees rarely end up on your partner's side.
- Less disturbance from a restless partner: Independent pocket springs limit how far movement travels, and the extra width here puts real distance between you, which helps more than any comfort layer can alone.
- A bigger step up than it sounds: Compared with the UK king, you gain 30cm of width and 15cm more each, at the same 200cm length, so the difference shows up where couples need it.
- Space when the household piles in: If a toddler or the dog is a regular overnight guest, the UK super king leaves the two adults a usable share rather than a narrow strip at each edge.
- Cushioning across a wide surface: The pillowtop softens the whole 180cm width, which means the middle of the bed is as comfortable as either side when a child ends up sleeping there.
This size suits you if...
You share with a partner who tosses and turns, or children and pets regularly climb in overnight, and your bedroom comfortably clears our suggested 3m x 2.9m minimum.
Consider another size if...
Your bedroom falls short of 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is the Relyon Prescott Pillowtop 1000 UK super king much bigger than the UK king?
Yes, in width. The UK super king is 30cm wider than the UK king, giving each of two sleepers 15cm more space, while both are 200cm long. You'll need more floor for it: we suggest at least 3m x 2.9m for the UK super king, against 2.7m x 2.9m for the UK king.
Is a UK super king pillowtop good for a restless partner?
It's one of the better set-ups for it. Pocket springs move independently, so a partner turning over causes less movement on your side, and at 90cm each you're physically further apart too. If the restlessness is serious, that distance usually helps more than the pillowtop cushioning does.
Will a super king Relyon Prescott Pillowtop 1000 fit in a loft conversion bedroom?
Only if the usable floor, where you can stand upright, reaches our suggested 3m x 2.9m. Sloping ceilings often decide which wall the bed goes against, so measure the full-height area rather than the total floor. If it's tight, the UK king is the more forgiving choice at 2.7m x 2.9m.
Is the UK super king Relyon Prescott Pillowtop harder to rotate?
A little, yes. Pillowtop mattresses can't be flipped, only rotated end to end, and at 180 x 200cm that's awkward for one person to manage. Plan on two people turning it, and clear space around the bed first so the corners don't catch on bedside tables.
What should I check before ordering a super king pocket spring mattress?
Measure the route as well as the room. Check that bedroom doors can swing open with the bed in place and that the mattress can clear any tight landing turns. Budget for bedding as well: a UK super king takes super king sheets and a 260 x 220cm duvet, which cost more than the smaller sizes.
