- Proper space for two: At 75cm each for two people sharing, you can both change position without waking each other, which matters most when one of you gets up hours earlier.
- Extra length for taller sleepers: The UK king is 10cm longer than the UK double, which means anyone approaching six foot stops sleeping with their feet at the edge.
- The top of this range: This is the biggest size the Unity Comfort Ortho comes in, so couples wanting maximum space from this mattress land here.
- A low-cost route to a bigger bed: Upgrading from a double to a king usually costs a lot; this mattress keeps the jump affordable, though you're buying with less published detail than usual.
- Standard bedding, easy to find: It takes ordinary UK king sheets and a 230 x 220cm king duvet, so there's no hunting for odd sizes.
This size suits you if...
You share the bed every night and a double has started to feel tight, especially if one of you tosses and turns or keeps different hours. It also makes sense if either of you is on the taller side, since the 200cm length is a genuine relief compared with a 190cm double. And if the dog treats the bed as its own, the extra width absorbs that too.
Consider another size if...
Your bedroom can't comfortably take it: we suggest at least 2.7m x 2.9m for a UK king. If your room is tighter than that, we'd recommend the UK double instead, where we suggest at least 2.6m x 2.8m.

Is the UK king the biggest size the Komfi Unity Comfort Ortho comes in?
Yes. The Unity Comfort Ortho tops out at the UK king (150 x 200cm), so there's no super king option in this range. If you want the widest bed this mattress offers, the UK king is it, giving 75cm each for two people sharing.
Will a UK king Komfi Unity Comfort Ortho fit in my bedroom?
We suggest allowing at least 2.7m x 2.9m, and that's our guidance rather than Komfi's. New build master bedrooms can be deceptive: once fitted wardrobes and bedside tables go in, the walking space around a 150cm wide bed shrinks fast, so measure with furniture in place.
Is a king worth it over a double for this mattress?
For most couples, yes. The UK king is 15cm wider than the UK double, which sounds modest but is felt every night, and it's 10cm longer too. Given this mattress sits at the budget end, the step up to the king is a comparatively cheap way to buy that extra space.
How much space does each person get on the UK king?
75cm each for two people sharing. That's enough for both of you to shift position, prop pillows or stretch out without constantly touching, which is the main reason couples upgrade from a double. During pregnancy, when you're rearranging pillows through the night, that extra width does real work.
Where can I buy the Komfi Unity Comfort Ortho in a UK king?
Availability changes, so the best approach is to compare the retailers listed on this page; the prices shown here are updated as retailers change them. Stock at the budget end can move around, so check back if the UK king isn't showing when you look.
