Layer Details
Cool-touch woven cover
A cool-touch fabric cover that Sleepeezee says is designed and proven to reduce body temperature. It means the surface feels cooler when you first lie down.
Pillow top with Staycool Gel
A plush pillow top infused with Staycool Gel. It adds extra cushioning, so the surface feels softer and more padded.
Staycool Gel layer
A pressure-sensitive gel layer that responds immediately to your body shape while managing moisture inside the mattress. You get contouring with less trapped heat.
High density polyester layer
Deep layers of high density polyester that add cushioning and resilience. They help the mattress feel comfortable and spring back over time.
Pocket and mini comfort springs
2300 individually wrapped pocket springs, with smaller mini comfort springs above the main spring system. The springs give you support, and the minis add a more responsive feel on top.

Key benefits
- 90cm each when you share: Each sleeper gets 90cm, which is 15cm more than the UK king, so a partner who turns over all night is simply further away from you.
- Space for a visitor at night: When a child climbs in after a bad dream, the 6ft width usually lets two adults make room, and the Calibre edge support keeps the outer strip usable.
- Cooling with two bodies in bed: Two sleepers produce more heat than one, so the cool-touch cover and Staycool Gel layers matter more here, with the extra width adding some distance between you.
- Same length as the UK king: At 200cm long, the UK super king matches the UK king for legroom, so the step up is purely about width, which suits couples who already fit lengthways.
- In proportion in a large room: In a period house or a generous master bedroom, the 180cm width keeps the bed looking settled where a UK king can seem a little lost.
This size suits you if...
You share the bed with someone who tosses and turns, or a young child or a large dog often ends up between you by morning, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m with room left for bedside tables.
Consider another size if...
Your bedroom is under 3m x 2.9m, or a door swing or tight landing turn would make the full width awkward. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a Sleepeezee Cool Refresh 2300 super king?
Two people sharing get 90cm each on the UK super king. That's 15cm more each than the UK king, which gives 75cm per person. If your partner moves a lot in the night, that extra gap tends to make more difference than any comfort layer, because you simply feel less of their movement.
What size bedroom do I need for a UK super king Cool Refresh 2300?
We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m will feel more comfortable once you add bedside tables and wardrobe doors. In a loft conversion, measure the full-height wall rather than the floor, as the slope often decides where the bed can go.
Is a super king Sleepeezee Cool Refresh big enough for two adults and a child?
For the odd night when a child wanders in, the UK super king gives you a realistic chance of everyone sleeping. The 180cm width means nobody is pushed right to the edge. If children or a large dog share as a nightly routine, it's still a squeeze, but a far gentler one than on a UK king.
Should I get the Cool Refresh 2300 in a UK king or UK super king?
The UK super king is 30cm wider than the UK king but the same length, so choose it only if you want more width. The UK king gives 75cm each and needs at least 2.7m x 2.9m, while the UK super king gives 90cm each and needs at least 3m x 2.9m.
What bedding fits a Sleepeezee Cool Refresh 2300 super king?
You'll need super king sheets and a 260 x 220cm duvet. The mattress is 27cm deep including the pillow top, so check that fitted sheets list a pocket deep enough for that before you buy. Super king bedding costs more than smaller sizes, so it's sensible to factor that in alongside the mattress.
