- 90cm of width each: Two people sharing get 90cm each, which means a partner who turns over frequently is far enough away that you simply stop noticing.
- 30cm wider than the UK king: The extra 30cm over the UK king is where children and pets fit without anyone being pushed to the edge.
- Springs that stay on your side: The twin layer of 4000 pocket springs responds to each sleeper separately, and across 180cm of width that independence has real room to work.
- The right scale for a big master: In a large master bedroom or a period property, a UK king can look undersized; the super king fills the space properly.
- Cooling matters more at this size: With more bodies sharing the bed, the cooling cover layer and dynamic airflow system have more heat to deal with, so they count for more here.
This size suits you if...
You share the bed every night and want enough distance that a restless partner no longer wakes you, your children or a large dog treat your bed as partly theirs, or your master bedroom is big enough that a UK king would look lost in it. We suggest at least 3m x 2.9m of floor space, with more feeling comfortable once wardrobes and bedside tables go in.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or you'd rather not pay super king bedding prices for space you won't use. We'd recommend the UK king instead, which is 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

Is the Brook + Wilde Ultima super king big enough for a family bed?
It's the most family-friendly size the Ultima comes in. At 180cm wide, two adults keep 90cm each, so a child climbing in during the night takes space from the middle rather than pushing anyone to the edge. If children or pets join you regularly, this is the size of the three that absorbs it.
How much space does each person get on the Ultima in a UK super king?
90cm each for two people sharing. That's the same width per person as a UK single, which is why couples on a super king can move, turn and starfish without touching. The twin layer of 4000 pocket springs also cushions movement locally, so the distance and the construction work together.
How big a bedroom does the Brook + Wilde Ultima need in a UK super king?
We suggest at least 3m x 2.9m of floor space, and that's a minimum rather than a comfortable fit. Before ordering, check the door swing clears the bed's footprint, and measure any landing turns or loft stairs on the route up, as a 180 x 200cm mattress is awkward to manoeuvre.
Should I choose the Ultima in a UK super king or a UK king?
The UK super king is 30cm wider than the UK king and the same length. If your room comfortably clears 3m x 2.9m and you share with a partner, children or pets, the extra width is the point of this size. In a tighter room, the UK king needs at least 2.7m x 2.9m and still sleeps two adults well.
Does the Brook + Wilde Ultima super king feel different from the smaller sizes?
The construction is identical across sizes, from the cooling cover down to the non-slip base. What changes is how that construction behaves with more room: pocket springs isolating movement matter more when a partner is 90cm away, and the airflow system has a larger surface to keep cool. The feel is the same; the experience of sharing isn't.
