Layer Details
- Cool-Touch Cover. A soft Cool Touch cover that helps maintain the correct temperature through the night. You'll feel it most on warm evenings, when the surface stays a little cooler against your skin.
- StayCool™ Gel. A generous layer of StayCool™ Gel that gently moulds to your body shape, which means personalised cushioning without the enveloping hug of traditional memory foam. The gel is also part of the mattress's temperature-management story.
- Pocket Springs. Individually pocketed springs at medium tension provide targeted support, each one adapting independently to your movements. That independence helps limit motion transfer if you share the bed.

- 90cm of width each: Two sharers each get 90cm, which means a fidgety partner's turning happens well away from you rather than right at your shoulder.
- Space for night-time visitors: When children wander in after a bad dream, the UK super king leaves room for them without anyone ending up clinging to the edge.
- Springs plus distance: Individually pocketed springs already limit motion transfer, and at this width there is more mattress between you, so movement reaches you less often.
- In proportion in a large room: In a period property or generous master bedroom, a UK super king looks properly scaled where a UK king can seem a little lost.
- A cooler surface on a busier bed: More bodies in the bed means more warmth, and the Cool-Touch cover and StayCool™ Gel layer are designed to keep surface temperature steadier.
This size suits you if...
You share the bed with a genuinely restless partner and want a full 90cm each, or small children and a large dog regularly end up in with you, 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 tight landing turns make a 180cm-wide mattress impractical. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

Will I feel my partner move on the Cool Response Gel Hybrid in a UK super king?
You should feel it less than on a narrower bed. The pocket springs work independently, which limits how far movement travels, and the UK super king adds physical distance on top. With 90cm each, a partner who tosses about or gets up early is further from you. For a genuinely restless sleeper, that distance tends to help more than any comfort layer.
How much more room does the Sleepeezee Cool Response super king give than the king?
The UK super king is 30cm wider than the UK king and the same length, so all the extra space goes into width. For two people sharing, that means 15cm more each: 90cm on the UK super king against 75cm on the UK king. We suggest at least 3m x 2.9m for the UK super king and at least 2.7m x 2.9m for the UK king.
Is a UK super king Cool Response big enough for two adults and a child?
Usually, yes, with a young child. On a 180cm-wide bed, the middle becomes shared ground, and a small child fits there far more comfortably than on a UK king. With older children, or more than one, it gets crowded quickly, as any mainstream size would.
Is the Cool Response super king a good choice if a large dog sleeps on the bed?
For most households, yes. With 180cm of width, a large dog curled along one side or at the foot still leaves you both room. The springs respond individually, so a heavy dog resettling in the night is less likely to jolt you. Expect a little more wear in the dog's favourite spot, so rotate the mattress regularly.
Will a Sleepeezee Cool Response super king fit in a loft conversion bedroom?
It can, but the slope usually decides where the bed goes. You need to sit up and get out on both sides without meeting the ceiling, so the headboard tends to take the tallest wall. Beyond that, allow at least 3m x 2.9m of floor you can actually stand in, rather than measuring to the skirting under the slope.
