Key benefits
- More room each: Sharing gives you 75cm each, which means a little more distance between you and your partner than the 67.5cm a UK double allows.
- Length for taller sleepers: At 200cm long, the UK king adds 10cm over a UK double, so anyone close to six foot is less likely to have their feet near the edge.
- Firm support across a wide surface: The firm Ortho spring unit runs the full 150cm width, which means both of you get the same held-up, traditional feel rather than sinking towards the middle.
- Sensible for most master bedrooms: We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable, so it often suits rooms where a UK super king would crowd the wardrobes.
- Easy to dress: Standard king sheets and a 230 x 220cm king duvet fit, although you will want fitted sheets with deep enough pockets for its 28cm depth.
This size suits you if...
You share the bed every night and keep brushing elbows on a UK double, or one of you is over six foot and the extra 10cm of length matters more than width. It also suits couples on different schedules who want a bit more space between them when one gets up hours before the other.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m, or you both want the space of a much wider bed. The Ortho King is only sold in a UK king, so there is no other size of it to choose.

FAQ's
Is the Ortho King UK king big enough for two people?
For most couples, yes. Sharing gives you 75cm each, which is 7.5cm more per person than the 67.5cm on a UK double. Yes, a UK super king gives 15cm more each than this, but the UK king does it without needing such a large room.
Is a UK king long enough if you're over six foot?
The UK king measures 200cm long, or 6ft 6in, which is 10cm longer than a UK double. That extra length gives a tall sleeper more room before their feet reach the end, so if height rather than width is your problem, this is the change that helps.
What size bedroom do you need for a UK king mattress?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable space to walk round. New build master bedrooms can feel tighter than expected once wardrobes go in, so measure your floor space with furniture in place, and remember you will need room to flip this two-sided mattress.
What bedding fits the British Bed Company Ortho King in a UK king?
Standard UK king sheets fit the 150 x 200cm surface, and a 230 x 220cm king duvet suits it. The mattress is 28cm deep, so check the pocket depth on any fitted sheet before buying, as shallower sheets can pull off at the corners.
How much less space does a UK king give than a UK super king?
The UK king is 30cm narrower than the UK super king, though both are 200cm long. Shared between two, that is 75cm each against 90cm each. The Ortho King itself is sold only in a UK king.
