- 90cm each for two sharing: Each of you gets 90cm of width, so a partner who turns over all night becomes far easier to sleep through.
- Room for night-time visitors: When a child pads in at 3am, or a large dog treats the bed as theirs, everyone still keeps a workable share of the mattress.
- Pocket springs across a wide surface: Pocket springs respond individually, which matters more at this width because movement on one side has further to travel before it reaches you.
- The largest standard UK size: At 30cm wider than a UK king, this is as much bed as mainstream retailers stock, so you are at the top of the range.
- Fills a large master properly: In a period property or a generous new build master, a smaller bed can look lost; this footprint suits the room.
This size suits you if...
You share the bed every night and want the maximum distance a standard size allows, your children or pets regularly join you and a UK king has started to feel crowded, or you have a large master bedroom where a smaller mattress would look undersized. Allow at least 3m x 2.9m of floor space, with something closer to 3.5m x 3.2m feeling comfortable around it.
Consider another size if...
Your bedroom is under 3m x 2.9m, or the landing turn on your stairs is tight, since a 180cm wide mattress is awkward to move. We'd recommend the UK king instead: it still gives 75cm each and we suggest at least 2.7m x 2.9m for it.

Is the Millbrook Wool Sublime Pocket 3000 super king much bigger than the king?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. Shared out, that means 15cm more width each for two people: the UK king gives 75cm per person, the UK super king 90cm. If disturbance from a partner is your main complaint, that extra width does more than any change of mattress model.
What room size do I need for this mattress in a UK super king?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add wardrobes and walking space. Check door swing and any landing turns too, because a 180cm wide mattress is the size where those start to bite. These are our own recommendations rather than Millbrook's.
Will the super king version fit through my house?
It is the hardest size to move: 180cm wide by 200cm long, and pocket sprung mattresses cannot be bent around corners the way foam ones sometimes can. Measure your stairwell, any landing turns and the bedroom door before ordering. Millbrook doesn't publish handling guidance for this size, so it's sensible to check access with the retailer listed on this page.
Is the UK super king worth it for a couple with young children?
This is the size where co-sleeping stops being a squeeze. With 90cm each for two adults, a child climbing in at night still leaves everyone a reasonable share, which a UK double or even a UK king struggles to manage. The same logic applies if a large dog shares the bed as routine.
What bedding does this size take?
Standard super king bedding fits the 180 x 200cm footprint: super king sheets and typically a 260 x 220cm duvet. Budget a little extra here, since super king bedding costs more than king sizes, and it's an ongoing cost that people sometimes forget when sizing up.
