Layer Details
Smart Latex
A 50mm layer of reactive natural latex foam that provides soothing support. Latex responds quickly to movement, which means gentle pressure relief without the sinking feeling of slower foams.
Pocket Springs
1,600 pocket springs (counted on the kingsize) work alongside the latex, each one individually encapsulated. This lets every spring react to your body shape on its own, which you'll feel as more tailored support and less disturbance from a partner's movement.

Key benefits
- Space that absorbs restlessness: With 90cm each for two people sharing, a partner who turns all night is far easier to ignore, and the pocket springs reduce what movement does carry across.
- Room for night-time visitors: When a child pads in at 3am, or the dog treats the bed as routine, the UK super king's 6ft of width means nobody ends up clinging to an edge.
- Latex feel across a wide surface: The 50mm graphite infused latex layer springs back quickly, so shifting position across a bed this wide never feels like wading through slow foam.
- Usable edges on both sides: Foam encapsulated edge support means the outer inches of that 180cm width are proper sleeping space, useful when three bodies end up sharing.
- Fits the larger master bedroom: In a period property or generous new build master, a UK king can look undersized against the wall, and the UK super king fills the space properly.
This size suits you if...
You share the bed every night and one of you is a genuinely restless sleeper, or children and pets regularly join you and you want everyone to keep a fair share of the mattress. It also suits you if your bedroom is comfortably over our suggested 3m x 2.9m minimum and you'd like a bed that matches the scale of the room.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for the UK super king. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is a super king mattress too big for a normal bedroom?
For many UK bedrooms, yes. We suggest at least 3m x 2.9m for the UK super king, and that's a minimum rather than a comfortable fit. Measure with wardrobes and door swing in mind, since a mattress this size can leave a smaller room feeling like all bed and no floor.
Is the Kaymed Smart Latex 1600 super king good for couples?
It's one of the better cases for sizing up. With 90cm each for two people sharing, a restless partner is simply further away, and the individually encapsulated pocket springs cut down motion transfer on top of that. The soft to medium feel suits side sleepers, so lighter couples who both sleep on their side are well matched.
Will the Kaymed Smart Latex 1600 super king get up my stairs?
At 180 x 200cm it's the trickiest mainstream size to move, and a tight landing turn or narrow loft staircase can defeat it. Measure your stairwell, any turns and the bedroom door swing before ordering. Kaymed doesn't publish specific handling guidance for this size, so check with the retailer if your access is awkward.
How much space is there if children share a super king?
More than any other standard UK size. Two adults get 90cm each, so when a child wanders in there's genuine room to absorb them rather than everyone shuffling to the edges. The foam encapsulated edge support helps here too, keeping the outer part of the mattress usable rather than a soft roll-off zone.
Does the Kaymed Smart Latex 1600 super king cost much more to run?
Bedding is the ongoing cost people miss: super king sheets and a 260 x 220cm duvet are pricier than king equivalents, so budget for that alongside the mattress itself. For the mattress price, compare the retailers listed on this page, as the figures shown are updated whenever retailers change them.
