Layer Details
- 90cm each for two sharing: You each get 90cm of space, which means a partner who turns over all night stops being your problem.
- Room for night-time visitors: When a child pads in at 3am, or the dog treats your bed as routine, everyone still gets a reasonable share of the 6ft width.
- Medium feel, edge to edge: The balance of cushioning and support holds across the full 180cm, so neither sleeper is pushed towards a softer or firmer patch.
- Fills a large master properly: In a period property or generous new build master where a UK king looks slightly undersized, the super king's footprint suits the room.
- Practical checks before you buy: Allow at least 3m x 2.9m of floor space, and remember super king bedding costs a little more and is stocked by fewer shops.
This size suits you if...
You share the bed every night with a restless partner and want distance rather than another comfort layer, children or pets regularly join you by morning, or your bedroom is large enough that a UK king would look lost against the wall. It also suits you if you've already decided on Tempur's medium feel, since this is the only size we currently see listed for this mattress.

What are the dimensions of the Tempur One Medium in a UK super king?
It measures 180 x 200cm, or 6ft x 6ft 6in. That's the largest size stocked as standard by UK retailers, and the extra length over a UK double or UK single also helps taller sleepers keep their feet on the mattress.
How much space does each person get on a super king?
Two people sharing a UK super king get 90cm each. For context, that's the width of a whole UK single per person, which is why restless couples find this size makes the biggest difference to undisturbed sleep, more than any change of firmness or material would.
Is the UK super king much bigger than a UK king?
The UK super king is 30cm wider than the UK king, with both sharing the same 200cm length. That 30cm sounds modest but it's the difference between brushing elbows and each having genuinely separate space, especially with a child or dog in the mix.
Will the Tempur One Medium super king fit in my bedroom?
We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add wardrobes and bedside tables. Measure door swings and landing turns too. At this size, getting the mattress up the stairs is often the tighter squeeze.
