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
- More room each than a double: At 150 x 200cm you each get 75cm, which means a little more distance between you and fewer elbows in the night.
- Length for taller sleepers: The 200cm length, or 6ft 6in, is 10cm longer than a UK double, so feet stay on the mattress rather than hanging off the end.
- Springs that work separately: The 2300 individually wrapped pocket springs respond on their own, which should help keep one partner's movement from carrying a long way across a wider surface.
- Firmer edges for getting up: Calibre edge support reinforces the perimeter, which makes sitting on the side and getting out of a larger bed a little easier.
- Cooler for two bodies: Two people share a lot of warmth, and the cool-touch cover and Staycool Gel layers are designed to manage heat and moisture across the surface.
This size suits you if...
You share the bed every night and find a double has started to feel cramped, or one of you is over six foot and keeps running out of length. It also suits couples on different schedules, where one of you gets up hours earlier and you'd both rather that went unnoticed.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once furniture is in. We'd recommend the UK double instead, where we suggest 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, which is 7.5cm more each than the UK double. That extra space sounds modest, but it means less contact when one of you turns over. If either of you sprawls, or a dog regularly joins you, the UK super king may suit you better.
Will a king size Cool Refresh 2300 fit someone over 6ft?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. For a partner approaching or over six foot, that length is often the bigger upgrade than the width. You get room to stretch out with your pillow top and feet both on the mattress.
What size bedroom do I need for a UK king Sleepeezee Cool Refresh 2300?
We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can feel smaller once wardrobes are fitted, so measure with your furniture in place and leave space to walk round both sides.
Should couples choose the king or super king Sleepeezee Cool Refresh 2300?
Both are the same length, so the choice comes down to width and room. The UK super king gives 90cm each, so the UK king gives you 15cm less each. If you have the floor space, we suggest at least 3m x 2.9m for the UK super king. Otherwise the UK king suits most couples well.
What bedding fits a Sleepeezee Cool Refresh 2300 king size mattress?
Standard UK king sheets fit, along with a 230 x 220cm king duvet. The mattress is 27cm deep with a pillow top, so check the pocket depth on fitted sheets before buying to make sure they tuck in fully at the corners.
