Key benefits
- Room for night-time visitors: When a child pads in at 3am, the extra width means nobody spends the rest of the night clinging to the edge.
- Distance from a restless partner: Pocket springs move independently, which means less motion travels across the bed, and 90cm each adds a physical gap that no comfort layer can replace.
- A proper share with a large dog: If your dog sleeps on the bed every night, the UK super king leaves you a real share of the mattress rather than a thin strip beside the duvet.
- 15cm more each than a UK king: Against the UK king, each sleeper gains 15cm of width at the same length, so the whole step up goes into elbow room.
- In proportion in a large room: In a period property or a generous master bedroom, a UK king can look slightly lost, whereas a full 6ft of width fills the space properly.
This size suits you if...
You share the bed with a genuinely restless partner, children or a large dog regularly end up joining you overnight, 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 your landing has tight turns. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Is a UK super king worth it over a UK king for a restless partner?
If movement is what wakes you, yes. The UK super king is 30cm wider than the UK king at the same length, giving each of you 15cm more. Pocket springs already limit motion, and that extra distance helps further. The trade-off is room size: we suggest at least 3m x 2.9m, against 2.7m x 2.9m for the UK king.
Can two adults and a child sleep on a UK super king mattress?
For the occasional early morning visit, usually yes. At 180cm wide, a small child can tuck in between two adults without anyone being pushed to the edge. It becomes a little cramped if the visits last all night and your child sprawls, but no mainstream UK size gives you more width than the UK super king.
Will a UK super king fit in a loft conversion bedroom?
It can, but the slope usually decides which wall the bed goes on. A 200cm length needs a full-height wall behind the headboard, or you will be sitting up under a low ceiling. Measure the usable floor area rather than the whole room, and allow at least 3m x 2.9m where you can actually stand.
How much space per person on the Spring King Wool Ortho Pocket in a UK super king?
Each sleeper gets 90cm, the same width as a UK single. By comparison, the UK double gives 67.5cm each, so the UK super king gives you 22.5cm more each. For couples who currently feel squeezed on a UK double, that is a very noticeable change.
What should I check before ordering a UK super king mattress?
Check that the bedroom door swings clear of the bed, and that there is space to walk round both sides. You will also need super king sheets and a 260 x 220cm duvet, which can mean replacing your bedding.
