The Kaymed range: foam, latex and pocket springs
Smart Phase pairs reflex foam with pocket springs: the Smart Phase 1600 is medium to firm, while the Smart Phase 2000 is soft to medium. Heavy Sleeper 1200 is a firm pocket-sprung hybrid with reflex foam. Smart Latex 3500 Box Top swaps in latex and has a medium-to-firm feel.
ClimaCool is the more cooling-focused range, with foam comfort layers over pocket springs. The ClimaCool 2000, 2200 and 3300 are listed firm; the 4400 and 5500 are medium, with more cushioning. Those differences in feel matter rather more to me than the weather forecast in the name.
Overheating wakes me, so a cooling promise gets my attention followed fairly swiftly by suspicion. Go carefully with the plushest foam tops if you're already kicking the duvet off. ClimaCool meeting a British bedroom in August is a more demanding encounter than a cool first touch in a shop.
I think Furniture Village asks a lot for its mattresses, so the ClimaCool name gets no extra allowance in the budget.
ClimaCool owners report warmth at night
On the Furniture Village shop floor, the ClimaCool 2000 felt cool to lie on, and the 3300's foam and cover felt fresh and cool at first contact. The 5500's deep foam made our tester wary of warmth.
"Not cool at all in the home" was one ClimaCool 4400 owner's verdict. A 3300 owner said it made them hot, and another who liked the mattress said it didn't keep them cool. When a mattress is named after the temperature, those are the owners I believe. August doesn't come with showroom air conditioning.
Gel in foam does a little for heat, in my view. Cooling covers and phase-change fabrics do less, so I don't pay for them. A thick, plush foam top holds more heat than a thinner top. The 3300 has 5cm of ClimaCool foam, the 4400 has 6cm and the 5500 has 8cm. Pick the 8cm top with care if you sleep hot.
Choose the cushioning because you enjoy sinking into it, and count any cooling sensation as an extra. Our mattresses for hot sleepers selection gives you alternatives if heat is your main concern. I prefer springs with breathable natural fillings for that job.
The firmer ClimaCools suit back and front sleepers
Back and front sleepers have the clearest reason to choose the firm models, while the 5500 gives side sleepers more room at the shoulder and hip. The ClimaCool 2000, 2200 and 3300 are listed firm. In store, the 2000 gave level back support, the 2200 felt steady through the centre and the 3300 was supportive without board-like hardness.
On the side, the 2000 needed more shoulder give, and the 2200 was too unyielding at the hip and shoulder. The 3300's cushioning was just about workable. Skip those firmer models if you spend most of the night on your side. Nobody is handing out medals for putting up with a mattress.
The medium 4400 felt plush initially and balanced when lying on the back, with comfortable shoulder give on the side. One owner found theirs much softer than the showroom mattress and sank in enough to struggle with turning over. On the medium ClimaCool 5500, the tester's shoulder and hip settled comfortably, although turning felt slower.
Steady edges were the consistent strength across the shop-floor trials, including under the 5500's soft top. You'll notice that when you share a bed and use its full width.
The model numbers are spring counts in a king. Our tester was wary of them, and I regard counts this high as marketing territory. You aren't sleeping on a spreadsheet. Compare the support and foam against other hybrid mattresses before paying more.
The plainer Kaymeds give you clearer buying choices
The Heavy Sleeper 1200 suits heavier sleepers seeking a firm surface, with reflex foam over pocket springs and a knitted cover. Its spring count is modest for a king, and 33cm is a tall mattress. Use our mattresses for larger people selection to compare support. Extra height isn't automatically extra cushioning: ask how much of the 33cm is foam.
For side sleeping, I favour the Smart Phase 2000: its soft-to-medium feel and reflex foam comfort layer over pocket springs offer a gentler option than the firm ClimaCools. A couple of owners describe it as very comfortable, with one also finding it expensive. Honestly, comfortable is the part you need. Compare the price with the ClimaCools and ignore the weather.
The Smart Phase 1600 is medium to firm, so it suits someone seeking less sink than the 2000. One owner bought a similar Kaymed to the one they'd slept on for years. Choose between these Smart Phase models by feel, because a bigger number is no reason to buy a softer bed you don't enjoy.
The Smart Latex 3500 Box Top combines natural latex with pocket springs and is listed medium to firm. Mattress Online lists the finish as a pillow top, so I'd pass. For one owner, it was their second Kaymed. Its 40cm depth also needs a careful look at bed height. Before you fall for the grand proportions, sit on a bed at that height and see whether your feet reach the floor comfortably.
