Layer Details
- Cool-touch knitted cover. A knitted cover with a cool-touch finish, proven to reduce body temperature. You'll feel it most when you first get into bed, when a warm surface is at its most noticeable.
- Built-in topper. A topper filled with mini springs and super soft memory foam, stitched into the mattress itself. This gives you the plush, cushioned first impression of a topper without a separate purchase.
- Dreamzone gel foam. Profiled, body-contouring gel foam that helps relieve pressure and draws heat away from your body. It cradles pressure points, which means less of the pins-and-needles feeling side sleepers sometimes get.
- Pocket springs and mini springs. Pocket springs and mini springs that adjust independently for optimal support. Because each spring moves on its own, you're less likely to feel a partner shifting during the night.

- A full 90cm each: Two sharers get 90cm apiece, which means a partner who fidgets all night can do so without ending up on your side.
- Independent springs across the full width: Pocket springs and mini springs move separately, so on a bed this wide a partner shifting over by the far edge barely registers where you lie.
- Space when the household piles in: If a small child or a large dog joins you most nights, the extra width means the adults keep a usable share rather than clinging to the edges.
- Cooling where more bodies add heat: Extra people and pets on one mattress generate warmth, and the gel foam and cool-touch cover are designed to draw that heat away from you.
- The same 200cm length as the UK king: At 6ft x 6ft 6in, taller sleepers gain the length of the UK king with 30cm more width on top.
This size suits you if...
You share with a partner whose tossing and turning wakes you, however comfortable the mattress, or children and pets regularly end up in your bed. It also suits you if you have a large master bedroom, perhaps in a period property, where a UK king would look a little lost against the wall.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 3m x 2.9m. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

Is the Sleepeezee SensaGel 9000 super king big enough for two adults and a child?
For occasional visits, yes. The UK super king measures 180 x 200cm, giving two adults 90cm each before a child arrives. Because the pocket springs and mini springs respond independently, a small child wriggling in the middle is less likely to jolt either adult awake. If it happens every night, you will still feel the squeeze, just a lot less than on a UK king.
How much wider is the SensaGel 9000 super king than the king?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. Shared between two people, that gives you 15cm more each. The trade-off is floor space: we suggest at least 3m x 2.9m for the UK super king, against at least 2.7m x 2.9m for the UK king.
Is a super king worth it over a double for a restless sleeper?
If a partner's movement is what wakes you, extra distance usually helps more than any comfort layer. The UK super king is 45cm wider than the UK double and gives 22.5cm more each for two sharing. The UK double needs at least 2.6m x 2.8m, so check your room can take the step up to 3m x 2.9m.
Will a SensaGel 9000 super king fit in a loft conversion bedroom?
Floor area is only part of the check. Allow at least 3m x 2.9m, then work out which wall has full headroom, because the sloping ceiling usually decides where a 180cm-wide bed can go. At 32cm deep this mattress sits fairly high, so think about how much clearance you want when you sit up in bed.
Is the SensaGel 9000 in super king a good choice if my dog sleeps on the bed?
For a large dog that sleeps with you every night, the UK super king is the size most likely to leave both of you enough room. With 90cm each for two people, a dog stretched across the foot or down one side takes a share without pushing anyone to the edge. The gel foam also helps manage the extra body heat a dog brings.
