Kaymed ClimaCool 5500 Mattress

Assessed from the specification published by Furniture Village, captured September 2026, and from regular price comparison across our UK retail partners.

If you're a hot sleeper, this is the sort of mattress designed with you in mind. The Phase Change particles in the foam absorb and release heat to keep the surface temperature steadier through the night, and the carbon crystals add to that cooling effect. The pocket springs, 5500 of them in the king size, respond independently to pressure, which means better postural support and less disturbance when a partner moves. The fillings are CertiPUR certified, so they're clear of harmful chemicals, and the cover is hypoallergenic, a genuine plus if you're sensitive to allergens. It's medium-feel, which suits most sleepers, and being single-sided means no heavy turning, just occasional rotation.

Warm sleepers
The foam comfort layer is infused with Phase Change particles and carbon crystals, which work to draw heat away so the surface feels steadier through the night.

Couples
Pocket springs, 5500 of them in the king size, respond independently to pressure, which means you feel less disturbance when your partner moves.

Allergy sufferers
A hypoallergenic cover and CertiPUR certified fillings make this a sensible pick if you are sensitive to allergens and want a cleaner sleep surface.

Side sleepers
Independently moving pocket springs respond to your shoulders and hips separately, so the medium feel can adjust to the curves of your body.

If you prefer a distinctly firm or soft mattress, this medium feel may not suit you. It's also a significant spend, so budget-conscious buyers may want to look elsewhere. And if you like a double-sided mattress you can flip, this single-sided design won't be for you.

Is the Kaymed ClimaCool 5500 good for hot sleepers?

Yes, cooling is its main strength. The comfort layer uses ClimaCool foam with Phase Change particles, which absorb and release heat to steady the surface temperature, plus carbon crystals for added cooling. If you regularly overheat at night, this is one of its strongest selling points.

How firm is the Kaymed ClimaCool 5500?

It's a medium-feel mattress, which suits most sleeping positions and body types. Back and side sleepers generally get on well with a medium, although if you're a heavier stomach sleeper who needs a firmer surface, you may find it slightly too forgiving.

Does the Kaymed ClimaCool 5500 need turning?

No. It's a single-sided mattress, so it never needs flipping. That's welcome given its 35cm depth, as a mattress this substantial would be heavy to turn. Rotating it from head to toe occasionally will still help the fillings settle evenly.

How many springs does the Kaymed ClimaCool 5500 have?

The king size contains 5500 pocket springs. Spring counts for other sizes aren't detailed on the retailer listing, and counts normally scale with mattress size, so smaller sizes will contain fewer. Each spring moves independently, which is what gives the mattress its postural support.

What guarantee comes with the Kaymed ClimaCool 5500?

Furniture Village lists a 20-year guarantee with this mattress, which is longer than most brands offer. As this is stated on the retailer's page rather than Kaymed's own, it's worth confirming the guarantee terms with whichever retailer you buy from.
