Layer Details
- ClimaCool foam comfort layer. A 5 cm layer of ClimaCool foam infused with Phase Change particles and carbon crystals. These work to absorb and release heat, which means a cooler sleeping surface through the night.
- Pocket springs. A base of 3,300 pocket springs in the king size. Each spring moves independently, so support follows the shape of your body and movement on one side is less likely to disturb the other.
Layer details from furniturevillage.co.uk product page, September 2026.
- The classic shared size: At 135 x 190cm, the UK double gives two people sharing 67.5cm each, enough for most couples without dominating the room.
- Cooling matters more when you share: Two bodies raise the temperature under one duvet, so the ClimaCool foam's Phase Change particles drawing heat from the surface count for more in a double than a single.
- Fits a typical UK bedroom: We suggest a room of at least 2.6m x 2.8m, which most main bedrooms in older terraces and new builds alike can manage.
- Pocket springs limit partner disturbance: Each spring moves independently, so one of you turning over is less likely to wake the other, useful in a shared size like this.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet fit, both stocked everywhere at every price point.
This size suits you if...
You share the bed every night and your bedroom sits around the typical UK size, where a UK king would crowd out wardrobes and bedside tables. It also suits solo sleepers who run hot and want proper room to spread out, or anyone whose main complaint is overheating and who prefers a genuinely firm feel underneath them.
Consider another size if...
You and your partner both like space and your room can take a bigger bed. The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m for the UK king.

Is the Kaymed ClimaCool 3300 in a UK double big enough for two adults?
For most couples, yes. Two people sharing a UK double get 67.5cm each, which works well if you sleep fairly close or your room can't take anything wider. The pocket spring base helps here too, since movement on one side is less likely to travel across. Restless sleepers or taller couples may prefer the UK king.
What room size do I need for the UK double ClimaCool 3300?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows for the mattress at 135 x 190cm plus space to walk around and open drawers. If you want bedside tables on both sides, measure the wall the bed will sit against before you commit.
Will the UK double Kaymed ClimaCool 3300 get up a narrow staircase?
It's a substantial mattress at 29cm deep and 135cm wide, and hybrids with pocket springs don't fold the way all-foam mattresses can. If you live in an older terrace with a turning staircase or a new build with a tight landing, measure the awkward point and check the retailer's delivery guidance before ordering.
Should couples pick the ClimaCool 3300 in a double or a king?
It comes down to your room. The UK king is 15cm wider and 10cm longer than the UK double, and we suggest at least 2.7m x 2.9m of floor space for it. If your bedroom clears that comfortably, the extra width is a real upgrade for two. If it doesn't, the UK double is the better fit.
