Layer Details
Responsive-Gel layer
A breathable, instantly responsive layer with gel beads for temperature control, designed to draw excess body heat away from the surface. It eases pressure while helping you stay cooler, which is useful if you tend to sleep warm.
Pocket springs
Individual springs, each in its own cloth sleeve, that move independently and contour to your body shape. You get support that follows your shape, and less disturbance when a partner moves. A high density foam encapsulated border around them gives edge-to-edge support.

Key benefits
- Real room for two: At 150cm wide you get 75cm each for two people sharing, enough to change position without elbowing your partner.
- Less disturbance on different schedules: Pocket springs compress individually, which means an early alarm on one side transfers far less movement to the other.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, a genuine relief if one of you is approaching six foot.
- Gel for warm sharers: Two bodies raise the temperature under one duvet, and the gel in the comfort layers is there to help with that heat.
- Fits most main bedrooms: We suggest at least 2.7m x 2.9m of floor space, which most UK master bedrooms can manage once wardrobes are accounted for.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you turns often or gets up hours before the other. It's also the size to pick if one partner is close to six foot, since the 200cm length stops feet reaching the end. Your bedroom offers at least 2.7m x 2.9m of clear space.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone and the width would go unused. We'd recommend the UK double instead, which needs around 2.6m x 2.8m of floor space.

FAQ's
How much space does each person get on a UK king mattress?
The Kaymed Signature Response Gel Pocket 1600 in a UK king is 150cm wide, which works out at 75cm each for two people sharing. That's noticeably more elbow room than a double, and because the pocket springs respond independently, each of you feels your own side of the bed rather than every movement your partner makes.
Is a UK king long enough for someone over six foot?
The UK king measures 150 x 200cm, or 5ft x 6ft 6in, and that 200cm length is 10cm more than a UK double. For anyone approaching or past six foot, the extra length is often the upgrade that matters more than the width, keeping feet on the mattress rather than hanging off the end.
Will the Kaymed Signature Response Gel Pocket 1600 UK king fit my bedroom?
We suggest allowing at least 2.7m x 2.9m of floor space for a UK king, which leaves room to walk round the bed and open drawers. New build master bedrooms can feel smaller than the plans suggest once fitted wardrobes go in, so measure the clear space that's left before committing to this size.
Should I choose the UK king or the UK super king?
The UK king is 30cm narrower than the UK super king; both are the same 200cm length. If you're upgrading for personal space or one of you is tall, the UK king usually does the job. Go for the UK super king if a dog or child regularly joins you, but allow at least 3m x 2.9m of room for it.
Where can I buy the Kaymed Signature Response Gel Pocket 1600 in a UK king?
Compare the retailers listed on this page; the prices shown are updated as retailers change them, so what you see reflects current availability.
