Layer Details
Cool-touch cover
A cool-touch knitted cover that starts regulating temperature as soon as you lie down. It gives the surface a fresher feel if you sleep warm.
Soft polyester comfort layer
Soft polyester fillings that provide the initial cushioning. You get a gentle first layer of softness as the pillow top eases you in.
Staycool Gel
A 2cm layer of pressure-sensitive Staycool Gel that draws away excess heat and manages moisture. It helps you stay comfortable through the night.
High-density support layer
A strong foundation for the layers above. It keeps the comfort layers supported over the springs.
1500 mini comfort springs
Gentle, responsive support springs. They add a more adaptive feel beneath the comfort layers.
800 traditional pocket springs
Strong, supportive springs that form the firmer core. They give the mattress its underlying support.
Foundation layer
A base layer that gives strong support to everything above it, helping the mattress keep its structure.

Key benefits
- Distance from a restless partner: With 90cm each, a partner who turns over all night is physically further away, and that gap does more for undisturbed sleep than any comfort layer can.
- 15cm more each than a UK king: The UK super king is the same length as the UK king, so every bit of the gain is width: 15cm more for each sleeper.
- Help with extra body heat: A child or a large dog adds warmth to a shared bed, so the cool-touch cover and 2cm Staycool Gel layer are especially welcome on a UK super king.
- Usable edges across the full width: On a UK super king, someone often ends up sleeping near a side, and Calibre edge side support helps the edges hold up when you sit or lie there.
- In proportion in a large master: In a period property or a generous master bedroom, a UK super king fills the floor in proportion, where a UK king can look a little lost.
This size suits you if...
Your partner moves about all night and you want real distance between you, or children and pets regularly end up in the bed, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your bedroom is smaller than 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
What room size do I need for a Sleepeezee Cool Refresh 2300 super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling more comfortable once bedside tables and walking space are in. In a loft conversion, check the ceiling slope as well, because it often decides which wall the headboard can sit against and whether you have headroom on both sides.
Is a super king big enough for two adults and a child?
It's the largest standard UK size, giving 180 x 200cm, or 90cm each for two adults. That leaves more slack for a small child climbing in than a UK king would. Three bodies still means less room each, but a UK super king gives everyone the best chance of a share.
How much wider is the Cool Refresh 2300 super king than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length. Split between two sleepers, that's 15cm more each. If your current UK king feels crowded mainly because of a partner moving about, the extra width is exactly where you'd notice the difference.
What size duvet and sheets fit a super king Sleepeezee mattress?
Super king sheets fit, and a 260 x 220cm duvet is the size to look for. The mattress is 27cm deep, so check that fitted sheets have pockets deep enough to tuck under comfortably, particularly with the pillow top adding height at the surface.
Will a super king mattress fit through my door and up the stairs?
At 180 x 200cm, a UK super king is a lot of mattress to manoeuvre. Before ordering, measure the narrowest landing turn, the stairwell ceiling and the swing of the bedroom door, then compare the retailers listed on this page once you know it will go in.
