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.
Layer details from furniturevillage.co.uk product page, September 2026.
- Cooling that both sleepers feel: The ClimaCool foam with Phase Change particles runs across the full 135cm width, which means neither partner is left on a warm patch.
- A footprint most rooms can take: At 4ft 6in x 6ft 3in, the UK double leaves space for bedside tables on both sides in a typical British bedroom.
- Room to plan around: Allow at least 2.6m x 2.8m and you'll still open the wardrobe, which is the practical test in an older terrace or a compact new build.
- Springs that ignore your partner: Pocket springs move independently, so one of you turning over doesn't tilt the other awake, useful at this shared width.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet fit, stocked everywhere at every price, so a premium mattress doesn't demand premium bedding hunts.
This size suits you if...
You share the bed every night and want a proper cooling design in the size most UK bedrooms were built around, or you sleep alone, run warm, and like space to spread out. It also suits a couple who'd rather give floor space to bedside tables and drawers than stretch to a bigger bed the room can't comfortably hold.
Consider another size if...
You and your partner both like room to sprawl, or one of you is broad shouldered, as 67.5cm each can feel snug. We'd recommend the UK king instead: 15cm wider, 10cm longer, and it needs a room of at least 2.7m x 2.9m.

Is the Kaymed ClimaCool 4400 UK double big enough for a couple?
Yes, with a caveat. The UK double is Britain's traditional couples' size, and at 135 x 190cm it gives two sharers 67.5cm each. That's fine for most, although restless sleepers or anyone over about six foot may feel the 190cm length. The pocket springs help here, absorbing movement so a snugger width disturbs you less.
What room size do I need for the ClimaCool 4400 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves walking room and space for bedside tables on both sides, which matters if you're planning a shared master bedroom rather than squeezing the bed against a wall. This is our guidance, not the manufacturer's.
Will the ClimaCool 4400 double fit up a narrow staircase?
It needs thought. This is a substantial 34cm-deep hybrid with a pocket spring unit, so it won't roll or fold like a boxed foam mattress. At 4ft 6in wide, the UK double usually manages turning stairs in older terraces, but measure your tightest landing and doorway first, and check the retailer's delivery guidance before ordering.
Does the UK double ClimaCool 4400 have 4,400 springs?
Kaymed quotes the 4,400 figure for the king size, and the brand doesn't publish a separate count for the UK double. A smaller footprint typically carries fewer springs of the same design, so support quality is the same even where the number differs. If the exact count matters to you, ask the retailer before buying.
Is the ClimaCool 4400 double a good choice for a guest room?
It's arguably more mattress than most guest rooms need, since you're paying a premium for cooling technology occasional visitors may never notice. That said, the UK double is the sensible guest size for visiting couples, and its 135 x 190cm footprint fits a spare room alongside a wardrobe.
