Key benefits
- Space for the 3am visitor: With 90cm each for two people sharing, a child who climbs in overnight lands in real space rather than wedging between you and waking you both.
- Distance from a restless partner: Open coil springs pass movement along the mattress, and the extra 15cm each over the UK king puts more surface between you to soak that movement up.
- No length lost: It matches the UK king at 200cm long (6ft 6in), so taller sleepers keep the same legroom and every extra centimetre goes into width.
- Room for a large dog: If a big dog sleeps across the foot of the bed most nights, the 6ft width means neither of you has to curl up to make room.
- In proportion with a big room: In a period property or large master bedroom, a UK super king fills a wide wall so the bed doesn't look lost in the space.
This size suits you if...
You regularly share the bed with a child or a large dog as well as a partner, or one of you tosses and turns enough that sheer distance matters most, and your bedroom comfortably clears our suggested 3m x 2.9m.
Consider another size if...
Your bedroom falls short of our suggested 3m x 2.9m, or tight landing turns would make a 180cm-wide mattress a struggle. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is a UK super king Braybrook big enough for two adults and a child?
For most families, yes. Two adults get 90cm each, so a small child who joins you partway through the night has somewhere to go without anyone ending up on the edge. The memory foam layer moulds to each body, which means a lighter child sinks in a little less than you do, but everyone still gets cushioning.
Will I feel my partner move on an open coil super king?
Probably a little. Open coil springs are connected, so a turn on one side travels across the unit, and Dreams Workshop doesn't use individually wrapped springs in this mattress. The UK super king softens that by giving you 15cm more each than the UK king, so there's more mattress between you before the movement reaches your side.
What size bedroom do I need for a UK super king mattress?
We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once bedside tables and the door's swing are allowed for. In a loft conversion, the sloping ceiling usually decides which wall the bed goes against. Measure your stairs and landing turns as well, then compare the retailers listed on this page.
Braybrook super king or king: which should I choose?
The UK super king is 30cm wider than the UK king and the same length. If you share with a restless sleeper, a child or a dog, that extra width makes the biggest difference on an open coil mattress like this one. If your room is tighter, the UK king needs at least 2.7m x 2.9m by our guidance.
What bedding fits a Braybrook super king mattress?
You'll need super king fitted sheets with pockets deep enough for the 21cm depth, plus a 260 x 220cm duvet. If you're moving up from a smaller bed, everything from sheets to mattress protector needs replacing, so plan for that alongside the mattress itself.
