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.
- 75cm each for two sharers: Two people get 75cm of width apiece, which means you can settle into your own sleeping position without negotiating for territory.
- 3,300 springs across the king width: The pocket springs move independently, so a partner leaving for an early shift is far less likely to wake you than on a shared double.
- 200cm of length for taller sleepers: The UK king is 10cm longer than the UK double, a real difference if one of you is approaching six foot and tired of dangling feet.
- Cooling that suits shared beds: Two bodies generate more heat than one, and the ClimaCool foam's Phase Change particles draw that warmth away rather than letting it build.
- Firm support edge to edge: The firm feel holds its shape across the full 150cm, so sleeping nearer the edge to claim space still feels supported.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, especially with a firm mattress where every centimetre of width is usable. Or one of you runs on a different schedule and you want the spring count and the extra space to absorb comings and goings. The 200cm length also suits you if either partner is tall enough to feel cramped on a standard 190cm mattress.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king. In that case we'd recommend the UK double instead, which needs a slightly smaller room, at least 2.6m x 2.8m by our guidance.

Is the Kaymed ClimaCool 3300 king good for couples on different schedules?
Yes, and better than most sizes of it. The king gives you 75cm of width each, and the 3,300 pocket springs in this size respond individually to movement. That combination means someone getting up hours before their partner causes less ripple across the surface, and the person still asleep has room to spread out once they've gone.
Will the UK king version suit a tall sleeper?
It's one of the better choices. At 200cm long, the UK king gives 10cm more length than the UK double, which matters once anyone in the bed approaches six foot. Because the ClimaCool 3300 is firm, your feet won't sink at the end of the mattress either, so the full length stays usable.
What room size does the Kaymed ClimaCool 3300 king need?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round the bed and open drawers. In a new build master bedroom, measure after accounting for wardrobes: rooms that look generous empty can feel tight once fitted furniture goes in. If you're short of space, the UK double needs at least 2.6m x 2.8m.
Should we choose the king or the super king ClimaCool 3300?
The UK king is 30cm narrower than the UK super king; both are the same 200cm length. If your main aim is escaping a cramped double, the king solves that for most couples. If a dog routinely joins you, or you simply want maximum separation, the super king adds width, but allow at least 3m x 2.9m of room for it.
How does the king compare with the double for this mattress?
The UK king is 15cm wider and 10cm longer than the UK double. On a firm mattress like this one, that extra width is all sleeping surface rather than soft edges you avoid, so the upgrade feels larger than the numbers suggest. Compare the retailers listed on this page to see current king pricing.
