Cool-Touch Surface
A sleeping surface that feels cool to the touch, designed to reduce body temperature. You'll notice it most when first getting into bed.
Staycool™ Gel
Pressure sensitive gel that responds immediately to your body shape, which means contouring without losing the firm feel. It also helps regulate body temperature through the night.
White fibre filling
This layer cushions spring movement and reduces allergens. A sensible inclusion if you're prone to allergies.
Pocket spring core
The spring system at the heart of the mattress, providing the underlying support.

Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, which means a restless partner's elbows and turns happen further away rather than right beside you.
- 15cm more each than the UK king: Compared with the UK king, you each gain 15cm of width at the same length, a slightly bigger buffer if a UK king has started to feel crowded.
- Space for small visitors: The full 180cm width leaves room for a child to climb in between you without either adult ending up clinging to the edge.
- Firm, cool surface across a big area: The cool-touch surface and Staycool gel cover the whole 180cm width, so extra bodies in the bed are spread across a firm, cooler top rather than bunched together.
- Suits a generous room: In a large master or a high-ceilinged period bedroom, a UK super king fills the space in proportion where a UK king can look slightly lost.
This size suits you if...
You share with a partner whose tossing and turning keeps waking you, or children and a dog regularly join you overnight, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is under 3m x 2.9m, or it is mostly just two calm adults in the bed. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Sleepeezee Cool Refresh 1600 UK king or UK super king for a restless partner?
The UK super king is 30cm wider than the UK king and the same length, which gives each of you 15cm more width. If your partner's movement is the main thing waking you, that extra distance helps. Choose the UK super king only if your room allows at least 3m x 2.9m. The UK king needs at least 2.7m x 2.9m.
How much bigger is the Cool Refresh 1600 super king than a double?
The UK super king is 45cm wider and 10cm longer than the UK double. For two people sharing, the UK double gives 67.5cm each and the UK super king gives 90cm each, so you each gain 22.5cm. You also get the longer 200cm length, which taller sleepers tend to notice.
Is a UK super king Cool Refresh 1600 big enough with a child in the bed?
For occasional night-time visits, yes. At 180cm wide, a small child can settle between two adults without anyone being pushed to the edge. The firm surface also stays level where a child lies. If two children join you most nights as well as a pet, even a UK super king will start to feel full.
Will the Cool Refresh 1600 in a UK super king suit a loft conversion bedroom?
It can, but measure carefully first. We suggest at least 3m x 2.9m of floor space, and around 3.5m x 3.2m feels more comfortable. In a loft conversion the sloping ceiling usually decides which wall the headboard goes against, so check you have full headroom where you will sit up and get out of bed.
Can a large dog share a Cool Refresh 1600 super king with two people?
With 90cm each for two adults across the 180cm width, there is more room for a dog than on any smaller size of this mattress. A large breed will still take a share, though. The firm feel helps here, because a heavy dog is less likely to leave a dip that tips you towards it.
