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
- More room each: At 75cm per person, the UK king gives each of you 7.5cm more than a UK double, which means fewer nudged elbows and less drifting into the middle.
- Length for a taller partner: The UK king is 10cm longer than a UK double, so a partner approaching 6ft can stretch out without their feet meeting the end.
- Easier on different schedules: If one of you gets up hours before the other, the extra width puts a little more distance between you as they climb out in the dark.
- Cooler with two in the bed: Two people make more heat, and the cool-touch cover sits over a 2cm Staycool Gel layer that Sleepeezee says draws excess heat away.
- Sides you can use: Calibre edge side support helps the sides hold up, which helps on a UK king where each of you has a wider half to spread across.
This size suits you if...
You share the bed every night and keep disturbing each other on a UK double, one of you is tall enough to notice the end of a 190cm bed, or you both sleep warm and want a medium feel.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m once the wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sleepeezee Cool Refresh 2300 UK king big enough for two people?
Yes, for most couples. The UK king gives you 75cm each, against 67.5cm each on a UK double, so you gain 7.5cm of personal space every night. If one of you sprawls, or the dog joins you as routine, that margin can still feel a little tight.
Is a UK king Cool Refresh 2300 long enough for someone over six foot?
It is 200cm long, which is 10cm more than a UK double. For a partner approaching 6ft, that extra length is often the real reason to upgrade, more than the width. Very tall sleepers will find the UK super king no longer, as both sizes share the same 200cm length.
What size bedroom do I need for a UK king Sleepeezee Cool Refresh 2300?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once bedside tables and wardrobe doors are in play. New build master bedrooms can look roomier than they are, so measure the room and the stairs, then compare the retailers listed on this page.
What duvet and sheets fit the Cool Refresh 2300 in UK king size?
Standard king sheets fit, and a 230 x 220cm king duvet suits the 150 x 200cm mattress. The mattress is 27cm deep, so check your fitted sheet's pocket depth before buying, as shallower sheets can pull off the corners.
Should couples choose the UK king or UK super king Cool Refresh 2300?
The UK super king gives 90cm each, so the UK king gives you 15cm less per person. If you sleep well together and your room is under 3m x 2.9m, the UK king is the sensible choice. Go bigger only if space between you is the main problem.
