Layer Details
- ClimaCool foam comfort layer. An 8cm layer of ClimaCool foam infused with Phase Change particles and carbon crystals. This is the temperature-regulating heart of the mattress, designed to keep the sleep surface cooler and more consistent through the night.
- Pocket springs. A layer of pocket springs, 5500 in the king size, each moving independently to give advanced postural support. That means the mattress responds to your shoulders and hips separately rather than as one flat surface.

- Real space for one: At 120cm across, the UK small double is 30cm wider than the UK single, which means a solo sleeper can genuinely spread out.
- Fits where a double won't: It's 15cm narrower than the UK double, and in a box room or loft conversion that difference can be what keeps a walkway clear.
- Cooling in a compact footprint: The ClimaCool foam with Phase Change particles draws heat away from you, useful in smaller rooms where warm air has less space to circulate.
- A substantial 35cm build: The full 35cm depth carries into this size, so sizing down to a UK small double doesn't mean a thinner mattress.
- Standard 4ft sizing: The small double is a standard UK size, so frames and 4ft fitted sheets are easy to find on the high street.
This size suits you if...
You sleep alone but have outgrown a single, perhaps a teenager's room where floor space matters, or a downsized bedroom where the old double simply won't go. It also works for a guest room where couples stay the odd night rather than every night, and you'd rather spend on comfort and cooling than on width nobody uses.
Consider another size if...
Two of you share the bed every night, or your room comfortably takes a wider mattress. At 120cm the UK small double is tight for nightly couples, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m for it.

Is a small double Kaymed ClimaCool 5500 big enough for a couple?
For occasional nights, yes. At 120 x 190cm two adults can share, and the pocket springs move independently so one person turning disturbs the other less. For every-night sharing it's a squeeze, and most couples would be happier on the UK double, which is 15cm wider at the same length.
What room size do I need for the ClimaCool 5500 in a small double?
We suggest allowing at least 2.4m x 2.8m. That leaves room to walk around the bed and open drawers or a wardrobe. If your room is smaller than that, measure carefully before buying, because the mattress is 120 x 190cm and the frame will add a little more on each side.
How does the UK small double compare to the UK king in this mattress?
The UK small double is 30cm narrower and 10cm shorter than the UK king. If your room can take it, the UK king needs at least 2.7m x 2.9m by our guidance, which is a fair bit more than the 2.4m x 2.8m we suggest for the UK small double.
Does the small double still get the full cooling technology?
Yes. The ClimaCool foam layer with Phase Change particles and carbon crystals is the same construction across sizes, and the 35cm depth carries through too. You're getting the full temperature-regulating build in a narrower footprint, which is part of why this size is still a significant spend.
Where can I buy the Kaymed ClimaCool 5500 in a small double?
Availability at this size changes, so compare the retailers listed on this page; the prices shown here are updated as retailers change them. The UK small double is a standard 4ft size, which also makes matching frames and bedding straightforward to source separately.
