Assessed from the specification published by Furniture Village, captured September 2026, and from regular price comparison across our UK retail partners.
The main reason to choose this mattress is heat. The ClimaCool foam uses Phase Change particles and carbon crystals, materials designed to absorb and move warmth away from your body through the night. Underneath, pocket springs respond individually to your shape for ergonomic postural support, so you get the contouring of foam without sleeping in it. The medium feel suits most back and side sleepers. The fillings are CertiPUR certified, meaning they've been checked as clear of harmful chemicals, and the knitted cover is hypoallergenic. Furniture Village, which lists the mattress, backs it with a 20-year guarantee, which is a long span of cover, though do note that guarantee is the retailer's own offer.
Key Features & what's inside
- 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.

Who's it NOT for?
If you prefer a distinctly firm or soft mattress, the medium feel here may disappoint. Budget shoppers should look elsewhere too: at £1,199 upwards, you're paying a premium largely for the cooling technology, and if you don't sleep hot, that money buys little you'll actually feel.
Kaymed ClimaCool 4400 Mattress
View all mattresses
Is the Kaymed ClimaCool 4400 good for hot sleepers?
Yes, cooling is its main strength. The comfort layer uses ClimaCool foam with Phase Change particles and carbon crystals, materials intended to regulate temperature through the night rather than just feel cool when you first lie down.
How firm is the Kaymed ClimaCool 4400?
It has a medium feel. That suits most back and side sleepers, although anyone who wants a noticeably firm surface, or a very soft, sink-in one, may find it sits too much in the middle.
How many springs does the Kaymed ClimaCool 4400 have?
The king size contains 4,400 pocket springs. Spring counts for other sizes aren't specified on the listing, so expect smaller sizes to differ. Each spring moves independently to support your posture.
Does the Kaymed ClimaCool 4400 come with a guarantee?
Furniture Village, which lists the mattress, offers a 20-year guarantee on it. That's the retailer's own cover rather than a manufacturer claim, so if you buy elsewhere, check what guarantee applies before you commit.
What sizes does the Kaymed ClimaCool 4400 come in?
It's available in UK Single, Small Double, Double, King and Super King, with prices from £1,199 to £1,899. All sizes are 34cm deep, so check your fitted sheets will stretch to a deeper mattress.
