Cover
A Cooler Extreme fabric cover with cool-touch properties, which means the surface feels noticeably cooler when you first lie down. It works by dispersing heat away from your body through the night.
StayCool gel
Pressure-sensitive StayCool gel that creates a supportive, edge to edge floating sensation. It also reduces heat build-up, so warm sleepers should feel a genuine difference.
Pocket springs and Softech springs
Pocketed and Softech springs deliver body-cushioning comfort, with 1,800 springs in the king size. Each spring moves independently, which means support that follows your shape rather than pushing back as one unit.
Superbond foam
Superbond foam forms part of the filling system, adding a stable comfort layer beneath the springs and gel.

Key benefits
- Leaves space for everything else: At 90cm wide, the UK single leaves floor space for a desk, wardrobe or toy storage, and we suggest a room of at least 2.1m x 2.8m.
- Cooling for one warm sleeper: The Cooler Extreme cover and StayCool gel draw heat away from the surface, which means a child or teenager who overheats has a better chance of sleeping through.
- Two beds for guests who won't share: Two UK singles side by side let a spare room host friends or siblings separately, each on their own set of pocketed springs.
- A feel that moves with the room: The medium feel suits most sleepers, so a UK single bought for a teenager can later become the guest bed without feeling out of place.
- Check raised frames first: At 30cm deep, it sits high on a bunk or cabin bed, so confirm the frame's maximum mattress depth and guard rail height before buying.
This size suits you if...
You sleep alone in a compact room and often wake up too warm, or you're furnishing a child's or teenager's bedroom where a desk and storage need the floor space more than the bed does.
Consider another size if...
You're an adult who likes to sprawl, or you share the bed even occasionally. We'd recommend the UK double instead, which gives 67.5cm each for two; allow at least 2.6m x 2.8m.

FAQ's
Will the Sleepeezee Cooler Extreme 1800 UK single fit a bunk bed or cabin bed?
It will fit the 90 x 190cm base of a standard UK single frame, but depth is the thing to check. At 30cm it sits high, which can reduce how much of the safety rail sits above the mattress on a top bunk. Look up your frame's maximum recommended mattress depth before ordering.
Is the Cooler Extreme 1800 in a UK single a good choice for a teenager who gets hot at night?
If overheating is the main complaint, yes. The cool-touch cover disperses heat and the StayCool gel reduces heat build-up, so it suits a warm sleeper in a small room. The medium feel suits most sleepers, although a teenager who sleeps mostly on their front may find the hips sink a little.
What size room do I need for a UK single Sleepeezee Cooler Extreme 1800?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk round the bed and open a wardrobe. For two UK singles in a shared children's room or guest room, you'll need noticeably more width so there's a clear walkway between them.
Should one adult buy the Cooler Extreme 1800 in a UK single or a UK double?
The UK single is 45cm narrower than the UK double, though both are the same length. If you sleep still and your room is tight, the UK single is fine. If you turn a lot or want room for a book and a cat, the UK double is more comfortable; allow at least 2.6m x 2.8m.
Does a UK single work in a spare room that doubles as a home office?
It suits that set-up well, because a 3ft wide bed pushed against one wall leaves space for a desk and chair. The medium feel and cooling layers mean an occasional guest gets a comfortable night, while on working days the UK single takes up as little of the room as a bed can.
