The Kaymed ClimaCool 4400 has a ClimaCool foam comfort layer infused with Phase Change particles and carbon crystals, which means it actively draws heat away rather than simply feeling cool to the touch at first. Beneath that sit pocket springs, 4,400 of them in the king size, for support that follows your posture. At 34cm deep it's a substantial mattress. If you're a hot sleeper who keeps waking up warm, this is one of the more purposeful cooling designs around, though the price asks you to take that cooling seriously.

Why should you choose this mattress?
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 & 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.

Best suited for?
Warm sleepers
The ClimaCool foam layer uses Phase Change particles and carbon crystals to draw heat away from your body, so you are less likely to wake up too warm.
Side sleepers
A medium feel combined with individually moving pocket springs lets the mattress follow your shape, which suits the contouring that side sleeping calls for.
Back sleepers
Pocket springs give ergonomic postural support and follow the curve of your spine, while the medium feel keeps your body from sinking too far.
Allergy sufferers
The knitted cover is hypoallergenic and the fillings are CertiPUR certified, which means they have been checked as clear of harmful chemicals.
If you prefer a distinctly firm or soft mattress, the medium feel here may disappoint. Budget shoppers should look elsewhere too: 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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
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. All sizes are 34cm deep, so check your fitted sheets will stretch to a deeper mattress.
