Layer Details
- Proper space for two: At 75cm each for two people sharing, a restless partner becomes background noise rather than a nightly nudge awake.
- Length for taller sleepers: The UK king runs to 200cm, which means anyone approaching six foot stops waking with their feet against the footboard.
- Kinder on different schedules: If one of you leaves for work hours before the other, the wider surface makes that early exit far less disruptive.
- Boxed delivery in the biggest size Komfi makes: Even at king size it arrives compressed and rolled, so it goes round tight landings without a two-person struggle.
- A budget route to upgrading: Moving up from a double usually costs a premium; here the low price makes the size jump easier to justify.
This size suits you if...
You share the bed every night and a double leaves you brushing elbows, one of you is tall enough that 190cm mattresses feel short, or you're upgrading a master bedroom on a tight budget and the size matters more to you than detailed specifications. It also suits couples where the dog has claimed a permanent spot and there's no longer enough mattress to go round.
Consider another size if...
Your bedroom is below the 2.7m x 2.9m we suggest for a UK king, or you sleep alone and the width would go unused. In either case we'd recommend the UK double instead; allow at least 2.6m x 2.8m for that size.

Is the Komfi Unity Comfort available in a UK king?
Yes, the UK king is the largest size Komfi makes this mattress in, measuring 150 x 200cm, or 5ft x 6ft 6in. It arrives rolled in a box like the smaller sizes, so delivery and moving it into the bedroom stay manageable. The prices shown on this page update as the retailer changes them.
Does the Komfi Unity Comfort come in a super king?
No. The UK king is the top of the range for this model, and the UK king is 30cm narrower than a UK super king. If you want the maximum sharing space a super king offers, you'll need a different mattress; if a king is enough, this remains one of the cheaper ways to get there.
Will a UK king fit in a new build master bedroom?
Often, but measure first. New build masters can feel smaller than the floor plan suggests once fitted wardrobes go in, and we suggest at least 2.7m x 2.9m for a UK king. If your room falls short, the UK double needs at least 2.6m x 2.8m and gives you back some walking space.
Is a UK king long enough for someone over six foot?
It helps considerably. The UK king is 10cm longer than the UK double as well as 15cm wider, and that extra length is usually the change a taller sleeper notices first. If length is your only complaint and your room is tight, remember the width increase comes as part of the package.
How much space do two people get on this king mattress?
You get 75cm each for two people sharing, which is a meaningful step up from a double and enough that one partner getting up early, or shifting position through the night, disturbs the other far less. Add a dog who treats the bed as home and the extra width stops being a luxury.
