Layer Details
Stretch knit cover
A soft, pliable stretch knit fabric that lets the fillings beneath contour to your body shape. It adds a gentle first layer of comfort without stiffening the surface.
Boxtop
A boxtop is deeper than a pillowtop and adds extra comfort layers over the springs. You get a plusher top feel, while the medium-firm feel underneath keeps it supportive.
Gel layer
A breathable, responsive gel layer with patented gel bead temperature control. It relieves pressure and disperses excess body heat away from the surface, which suits you if you sleep warm.
Pocket springs
Individual, independent springs that contour to your body shape and minimise partner disturbance. If your partner moves a lot in the night, you should notice less of it.
Foam encapsulated border
A high density foam border surrounds the spring system for edge-to-edge support. It helps prevent the feeling of roll-off, so you can use more of the bed and sit on the edge more comfortably.

Key benefits
- 90cm of width each: Two people sharing get 90cm each, which means turning over, spreading out or reading late rarely disturbs the person beside you.
- Distance beats any comfort layer: If your partner genuinely thrashes about at night, no amount of pocket springs helps as much as the extra space a UK super king gives you.
- Room for night-time visitors: When a child pads in at 3am, or the dog treats the bed as routine, everyone still gets a workable share of the 180cm width.
- Full 200cm length: At 6ft 6in long, taller sleepers get the same generous length as the UK king, with 30cm of extra width on top.
- Fills a large master properly: In a period property or a generous new build master, a UK super king sits in proportion where smaller sizes can look undersized.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is restless enough that distance matters more than mattress construction, or children and pets regularly join you and you'd rather everyone fitted. Your bedroom should comfortably clear our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room is under our suggested 3m x 2.9m minimum, or the bed would dominate the space. 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
How big is the Kaymed Signature Response Gel Pocket 2500 Boxtop in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That gives two people sharing 90cm each, which is the most sleeping space you'll get from a standard UK mattress size without moving to zip and link or custom widths.
How much bigger is the UK super king than the UK king for this mattress?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. All of the extra space goes into width, which is exactly where it helps if you share with a restless partner or with children who wander in overnight.
Will the super king version of this Kaymed mattress fit in my bedroom?
We suggest a room of at least 3m x 2.9m for a UK super king, and a little more feels better in practice. Measure with wardrobes, door swing and walking space in mind, because a bed this wide changes how the whole room works, especially in a loft conversion where the slope limits which wall it can take.
Is the super king a good choice if my partner is a restless sleeper?
Yes, and arguably it matters more than the mattress itself. With 90cm each, most of a partner's movement simply happens too far away to wake you. If one of you tosses and turns nightly, sizing up to the UK super king often does more for your sleep than any comfort layer.
Can I get this mattress upstairs in a super king?
This is the size where staircases bite. A UK super king is a large one-piece mattress, so measure your landing turns, door widths and stairwell before ordering. Kaymed doesn't publish a weight or handling guidance for this model, so it's sensible to confirm delivery access requirements with the retailer first.
