Key benefits
- More room each night: Moving up from a UK double adds 7.5cm per person, which sounds small on paper but means elbows and knees stop meeting in the middle.
- Length for taller partners: At 200cm long, the UK king gives 10cm more than a UK double, so someone around six foot can stretch out without their feet hanging off the end.
- Quieter early starts: Pocket springs that each sit in their own cloth pocket help limit movement travelling across 150cm, useful if one of you gets up hours before the other.
- A cooler shared surface: Two bodies give off more heat than one, and the 50mm graphite-infused latex layer is designed to give a cooling finish across the whole sleeping area.
- Usable sides: The reinforced edge helps the sides keep their shape, so the outer part of each 75cm half stays comfortable to lie on rather than sloping away.
This size suits you if...
You share the bed every night and have started to feel cramped in a UK double, one of you is close to six foot and keeps running out of length, or your sleep patterns differ and you want a little more distance from each other's movements.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Kaymed Smart Latex 2400 Pillow Top UK king big enough for two adults?
For most couples, yes. The UK king gives each of you 75cm, compared with 67.5cm on a UK double. If you both sprawl or a dog regularly joins you, the UK super king offers 90cm each, though it needs a room of at least 3m x 2.9m.
What size bedroom do I need for a UK king Kaymed Smart Latex 2400?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can feel tighter than their plans suggest once wardrobes and bedside tables go in, so measure the space you'll actually have left before you compare the retailers listed on this page.
Is a UK king long enough if my partner is over six foot?
It's 200cm long, or 6ft 6in, which is 10cm more than a UK double. For a tall sleeper, that extra length is often the bigger improvement than the width, as it lets them lie straight without their feet pressing against a footboard.
Will a king size help if my partner gets up much earlier than me?
It should help. The extra 7.5cm each over a UK double puts a bit more distance between you, and the individually pocketed springs respond to the person pressing on them, which reduces how much a partner climbing out of bed is felt on the other side.
What bedding fits the Kaymed Smart Latex 2400 Pillow Top in a UK king?
Standard king sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet covers it well. The mattress is 34cm deep with a quilted pillow top, so check that the pocket depth on your fitted sheets suits a 34cm mattress before buying.
