Layer Details
ClimaCool foam comfort layer
A 6cm layer of ClimaCool foam infused with Phase Change particles and carbon crystals. These work to regulate temperature, which means heat is drawn away from you rather than building up where you lie.
Pocket springs
A pocket spring unit, with 4,400 springs in the king size, provides ergonomic postural support. Each spring moves independently, so the mattress follows the shape of your spine rather than pushing back as one flat surface.

Key benefits
- Cooling in a compact footprint: The ClimaCool foam draws heat away through Phase Change particles and carbon crystals, which matters even more in a small, warm bedroom where air doesn't move much.
- Fits where other sizes can't: At 90cm wide it slots into rooms of just 2.1m x 2.8m by our guidance, leaving space for a wardrobe and desk alongside.
- Springs that work for one sleeper: Pocket springs respond to your shape individually, so a lighter teenager gets contouring rather than lying on top of a surface tensioned for two.
- A medium feel most people settle into: The medium firmness suits back and side sleepers, a sensible default when the bed may pass from teenager to guest use later.
- Guest rooms done properly: Two UK singles suit a spare room hosting different visitors better than one double, and this one gives guests a genuinely comfortable night rather than an afterthought.
This size suits you if...
You sleep alone and your room is on the smaller side, you run hot at night and want cooling that actually does something in a compact space, or you're furnishing a guest room and want single beds that guests will remember kindly. It also suits a teenager's room where a hot sleeper needs the temperature control more than extra width.
Consider another size if...
You're an adult who likes to spread out, or you find 90cm of width restrictive. The UK small double is 30cm wider at the same length, and we suggest a room of at least 2.4m x 2.8m for it.

FAQ's
Will the Kaymed ClimaCool 4400 in a UK single fit a bunk or mid sleeper bed?
Probably not, and it's worth checking carefully. At 34cm deep, this is a substantially taller mattress than most raised frames allow, since guard rails need to sit well above the mattress surface. Check your frame's maximum mattress depth before buying; many bunks specify 20cm or less.
What room size do I need for a UK single Kaymed ClimaCool 4400?
We suggest a minimum floor space of 2.1m x 2.8m. The mattress itself is 90 x 190cm, so that guidance leaves room to walk alongside the bed and open drawers or a wardrobe. In a child's room competing with toy storage and a desk, the single's narrow footprint is exactly why it's the default choice.
Is the UK single Kaymed ClimaCool 4400 big enough for an adult?
For most solo adults, yes. At 90 x 190cm it's the standard UK one-person size, and the pocket springs support a single sleeper's posture without needing a partner's weight to balance the surface. Taller adults should note the 190cm length; the UK king is 10cm longer if you need it.
Should I buy the single or size up to the UK small double?
If your room allows it and you like space to sprawl, the UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it. In a compact room, or for a child or teenager, the UK single is the more practical fit.
Is this a sensible mattress for a teenager's room?
It can be, with a caveat. The cooling foam and medium-feel pocket springs suit a teenager who sleeps hot, and the single size fits a typical teen bedroom. This is a premium mattress though, so it makes most sense if the bed will serve them for years rather than being outgrown quickly.
