- Proper space for two: At 75cm each for two people sharing, you can both change position without negotiating for territory in the small hours.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, which means anyone approaching 6ft finally stops finding the footboard with their toes.
- Springs that limit disturbance: The twin layers of 2000 nano-springs and 4000 pocket springs move independently, so an early riser slipping out is less likely to wake you.
- Room for real life: A dog who treats the bed as his own, or a toddler arriving at 6am, is easier to absorb across 150cm of width.
- Fits a normal master bedroom: We suggest at least 2.7m x 2.9m, which most UK master bedrooms can manage where the UK super king would feel a squeeze.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, one of you is tall enough that the extra 10cm of length over the UK double genuinely matters, or your sleep is regularly broken by a partner on a different schedule and you want space and springs working together to reduce it.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest, perhaps a new build master that shrinks once the wardrobes go in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is the Brook + Wilde Ultima UK king big enough for two adults?
Comfortably, for most couples. At 150 x 200cm you each get 75cm of width, enough to sleep spread out rather than in parallel lines. If you routinely share with a dog or a wandering child as well, it still works, although the UK super king is 30cm wider if space is the whole point of the upgrade.
What room size do I need for a king size Ultima?
We suggest at least 2.7m x 2.9m for a UK king, which leaves enough room to walk round the bed and open drawers without shuffling sideways. That's our guidance rather than the brand's. Measure with your wardrobes and bedside tables in mind, since a room that looks generous empty can tighten up quickly once furniture arrives.
Is the UK king Ultima long enough for someone over six foot?
At 200cm, or 6ft 6in, it gives a taller sleeper meaningful headroom. The UK king is 10cm longer than the UK double, and that length is often the real reason tall people upgrade, more than the width. If you're well over six foot, the UK super king is the same length, so sizing up buys width only.
How much bigger is the king Ultima than the double?
The UK king is 15cm wider and 10cm longer than the UK double. That sounds modest on paper, yet across two sleepers it's the difference between brushing elbows and having a settled side each. If your double already feels fine for space and your room is tight, the saving in floor area may matter more than the upgrade.
Will the Ultima in a UK king help with partner disturbance?
The width does a lot of the work: 75cm each means less accidental contact when one of you turns. The construction helps too, with twin layers of 2000 nano-springs and 4000 pocket springs that respond locally rather than rippling movement across the bed. Neither makes a restless partner silent, but together they take the edge off broken nights.
