- 90cm of width each: Two people sharing get 90cm each, which means a restless partner is simply further away, and the independent pocket springs pass on even less of their movement.
- Extra firm across a full 6ft: The extra firm surface stays supportive edge to edge, so a couple with different sleeping positions can each use their full half without drifting into a softer middle.
- Space for night-time visitors: When a child pads in at 3am, or a large dog treats the bed as its own, 180cm of width means the adults still get a fair share.
- Same length as a UK king: At 200cm long, sizing up from a UK king adds 30cm of width without changing the length, so taller sleepers lose nothing in the trade.
- A firm bed that suits sprawling: Front and back sleepers who like a solid feel tend to spread out, and this size gives that habit room without crowding a partner.
This size suits you if...
You share the bed every night and one of you moves around enough to wake the other, or children and pets regularly join you and a UK king has started to feel crowded. It also fits a large master bedroom, where anything smaller can look a little lost. You both want an extra firm feel, since sizing up won't soften the mattress for either of you.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you'd struggle to get a 180cm mattress round your landing. We'd recommend the UK king instead, which is 30cm narrower and needs at least 2.7m x 2.9m.

What room size do I need for a super king Silentnight Pocket Essentials 1400?
We suggest a room of at least 3m x 2.9m for the UK super king, which leaves walking space either side and clearance for the door. That's our guidance rather than Silentnight's. Measure the door swing and any wardrobes before committing, because at 180 x 200cm this mattress dominates a smaller room.
Is the super king version of this mattress firmer than the smaller sizes?
No, the extra firm feel is the same in every size. What changes is space: two people sharing the UK super king get 90cm each, so you feel less of a partner's movement on top of what the pocket springs already absorb. If the firmness worries you, that's a model question, not a size one.
Will a super king mattress get up my stairs?
At 6ft x 6ft 6in, this is the hardest standard size to move. Pocket spring mattresses flex less than foam, and an extra firm one like this bends least of all, so tight landing turns and narrow staircases are a genuine risk. Measure the awkwardest corner of the route before you order, including door frames.
Is the Pocket Essentials 1400 Ortho super king good for couples with kids or pets?
It's one of the better cases for this size. With 180cm of width, a child climbing in at night or a large dog at the foot of the bed doesn't force anyone to the edge. The extra firm surface also holds its shape under extra bodies rather than sagging towards the heaviest sleeper.
Should I choose the UK king or the UK super king in this mattress?
If you sleep alone or your room is on the smaller side, the UK king does the job and needs at least 2.7m x 2.9m by our guidance. The UK super king is 30cm wider, the same length, and makes sense for couples who share with children or pets, or where one partner is genuinely restless.
