Layer Details
ClimaCool foam comfort layer
A 5 cm layer of ClimaCool foam infused with Phase Change particles and carbon crystals. These work to absorb and release heat, which means a cooler sleeping surface through the night.
Pocket springs
A base of 3,300 pocket springs in the king size. Each spring moves independently, so support follows the shape of your body and movement on one side is less likely to disturb the other.

Key benefits
- Stretching room for one: The UK small double is 30cm wider than the UK single, which means a solo sleeper who sleeps hot and moves about has genuine space to do it.
- Fits where a double will not: At 15cm narrower than the UK double, this size can be the difference between a door that clears the bed frame and one that doesn't.
- Cooling in a compact room: Smaller bedrooms often run warmer, so the ClimaCool foam's Phase Change particles drawing heat away from the surface matters more here than in a big airy room.
- Firm support at 29cm deep: You get the full 29cm depth and firm hybrid feel of the larger sizes, so choosing the compact footprint means giving up width, nothing else.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets are simple to find and a standard double duvet drapes generously over the sides.
This size suits you if...
You're a solo adult who has outgrown a single but can't spare the floor space a UK double demands, you're furnishing a loft conversion or box room where every centimetre of width counts, or you're kitting out a guest room where couples stay occasionally rather than nightly. Because this mattress is firm and built for hot sleepers, it also suits a warm solo sleeper wanting a supportive upgrade in a compact room.
Consider another size if...
You share the bed with a partner every night, in which case a UK small double will feel tight over time. We'd recommend the UK double instead: it's 15cm wider, the same length, and needs a room of at least 2.6m x 2.8m.

FAQ's
Is a small double big enough for a couple on the Kaymed ClimaCool 3300?
For occasional nights, yes. Two adults can share a UK small double comfortably enough for a weekend stay, which makes this size a sensible guest room choice. For every night, most couples find 120cm of width restrictive, and we'd point you to the UK double, which is 15cm wider and needs a room of at least 2.6m x 2.8m.
What room size do I need for the Kaymed ClimaCool 3300 in a small double?
We suggest at least 2.4m x 2.8m. That allows walking space around the bed and room for the door to open cleanly, which is often the deciding factor in box rooms and studio flats. If your room is smaller than that, it's worth measuring with the wardrobe doors open before you commit.
Is the small double ClimaCool 3300 worth it over the single?
If you have the room, usually yes. The UK small double is 30cm wider than the UK single and the same length, so a restless or broad-shouldered sleeper gets meaningfully more space to spread out. Given this is a firm mattress designed for hot sleepers, that extra width lets you move to a cooler patch of the surface too.
What bedding fits a small double Kaymed ClimaCool 3300?
You'll need small double (4ft) fitted sheets, and check they're deep enough for the 29cm mattress before buying, as shallower sheets will ping off the corners. A standard double duvet works well on top, hanging a little further over each side than it would on a UK double, which many solo sleepers rather like.
