Layer Details
Cooler Extreme cover
The mattress is topped with Sleepeezee's Cooler Extreme fabric cover.
Pillow top
A built-in pillow top cushions the surface for extra body support. It gives that plush, sink-in first impression without needing a separate topper.
StayCool gel
Pressure-sensitive StayCool gel contours to your body, creating an edge to edge floating feeling. Its thermal control regulates body temperature and reduces heat build-up, which means less of the clamminess softer mattresses can cause.
Superbond foam
A layer of Superbond foam filling sits beneath the gel, adding cushioning between the comfort layers and the springs.
Pocket springs and Softech springs
2,400 pocket springs work alongside Softech springs for total-body support. Because each spring moves independently, you should feel less disturbance from a partner shifting in the night.

Key benefits
- Room to sprawl on your own: You get 30cm more width than the UK single, which means space to turn, stretch out and change position without hanging off the edge.
- Fits tighter bedrooms: Being 15cm narrower than the UK double, it can leave enough floor for a door to swing open or a wardrobe to be reached in a small room.
- Cooler for a lone warm sleeper: StayCool gel is designed to reduce heat build-up, which suits one person who runs warm but still wants a plush pillow-top feel.
- Workable for occasional couples: Independent pocket springs mean less disturbance when a visiting partner moves, although nightly sharing on this width will feel a little snug.
- Easy bedding and frames: At a standard 4ft width, small double fitted sheets and frames are straightforward to find in UK shops.
This size suits you if...
You sleep alone, like room to spread out and have moved beyond a single, or your spare room hosts a couple now and then but nobody sleeps there every night.
Consider another size if...
You share with a partner every night and want your own side. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for that room.

FAQ's
Will a Sleepeezee Cooler Extreme 2400 UK small double fit a box room?
Often, yes. We suggest allowing at least 2.4m x 2.8m for a UK small double. Measure where the door swings and where any wardrobe opens, because the 120cm width is usually what decides whether you can still get in and around the bed comfortably.
Is the Cooler Extreme 2400 small double big enough for a teenager?
For most teenagers who have outgrown a single it is a sensible step up, adding 30cm of width over the UK single at the same length. That extra room suits restless sleepers, and the medium pillow-top feel gives cushioning without needing a separate topper.
Can a couple use the Cooler Extreme 2400 small double in a guest room?
For occasional stays, yes. The independent pocket springs help limit disturbance when one person turns over, which matters more on a narrower bed. Guests used to a larger bed may find it a little cosy over several nights, so it suits visitors rather than a couple sleeping there permanently.
Is the Cooler Extreme 2400 good in a small double for a loft conversion?
It can be a good fit where sloping ceilings limit the floor you can stand on, because the UK small double is 15cm narrower than the UK double. Bear in mind the mattress is 32cm deep, so check headroom above the bed on your chosen frame.
