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.

Key benefits
- 90cm each, every night: Two people sharing get 90cm of width apiece, which means you can both change position freely without ever brushing elbows.
- Cooling across the full width: The ClimaCool foam layer runs across the whole 180cm surface, so both sleepers get heat drawn away rather than one lucky side.
- Pocket springs keep movement local: Each spring compresses independently, which means a partner turning over on their side of a bed this wide barely reaches you at all.
- Room for the whole household: When children or pets treat your bed as theirs too, the extra width means everyone still gets a workable share of the mattress.
- Full-length stretch for taller sleepers: At 200cm long, the UK super king is 10cm longer than a UK double, so anyone around 6ft can stretch out without their feet hanging off.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, you or your partner sleep restlessly and distance matters more than any comfort layer, or children and pets regularly join you and 90cm each keeps that manageable. Your bedroom should measure at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your bedroom is under the 3m x 2.9m we suggest for a UK super king, or you'd rarely use the extra width. We'd recommend the UK king instead: it's 30cm narrower at the same length, and needs at least 2.7m x 2.9m.

FAQ's
Will the Kaymed ClimaCool 4400 super king fit in a 3m wide bedroom?
Just about. We suggest a minimum of 3m x 2.9m for a UK super king, which leaves enough clearance to walk around the bed and open drawers. It will feel snug at that size, though. Around 3.5m x 3.2m gives the room space to breathe, particularly with bedside tables on both sides.
How many springs does the super king version have?
Kaymed quotes 4,400 pocket springs for the king size, and doesn't publish a separate count for the UK super king. What matters more in practice is that the springs move independently, so across a 180cm width your partner's movements stay firmly on their side of the bed.
How much bigger is the super king than the king for this mattress?
The UK super king is 30cm wider than the UK king, and the two are exactly the same length at 200cm. All of that extra width goes into elbow room: 90cm each for two people sharing, which is the same width per person as a UK single.
Can two restless sleepers share the Kaymed ClimaCool 4400 super king comfortably?
This is arguably the size's strongest case. With 90cm each, most tossing and turning happens too far away to notice, and the pocket springs absorb what's left because each one compresses on its own. If one of you also sleeps hot, the ClimaCool foam works on the heat while the width handles the fidgeting.
Is the super king practical if children climb in at night?
More than any other standard UK size. At 180cm wide, a child squeezing in between you still leaves both adults a reasonable share, where a UK king would start to feel crowded. The medium feel and independent springs also mean a small body wriggling in the middle disturbs the edges less than you'd expect.
