- Genuine distance from a fidgety partner: With 90cm each for two people sharing, movement on one side simply happens further away, and the pocket springs limit what little does travel across.
- Space for the whole household: A child wandering in at 3am, or a dog who considers the bed home, no longer means someone sleeping on the edge.
- 30cm wider than the UK king: That extra width across the bed is the difference between a comfortable night for two and a properly luxurious one.
- Usable edges at this scale: The comfort foam perimeter firms up the sides, so all 180cm of width counts rather than tapering off near the edge.
- Medium feel that works for mismatched sleepers: The medium firmness suits most positions, useful in a bed this size where two people rarely sleep the same way.
This size suits you if...
You share the bed every night and a UK king has started to feel cramped, your partner is restless enough that distance matters more than any comfort layer, or children and pets regularly join you and everyone still needs their own patch. A large master bedroom, where a smaller bed would look lost against the wall, also makes the case for this size.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 3m x 2.9m, or you'd rather keep bedding costs down. We'd recommend the Emma Original in a UK king instead, which is 30cm narrower but far easier to house.

Is the Emma Original super king big enough for a couple and a child?
Comfortably, most nights. Two adults get 90cm each across the 180cm width, so a small visitor in the middle still leaves everyone room to lie normally. It's the size we'd point parents towards if night-time visits are routine rather than occasional, since a UK king starts to feel tight with three.
How much bigger is the super king than the king in the Emma Original?
The UK super king is 30cm wider than the UK king, at 180 x 200cm against 150 x 200cm. Both are the same length, so the gain is entirely in width across the bed. If your complaint is elbows and cold shoulders rather than feet hanging off the end, the UK super king solves it.
What room size do I need for the Emma Original super king?
We suggest a minimum of 3m x 2.9m, and around 3.5m x 3.2m feels right if you want bedside tables on both sides and space to walk around the foot of the bed. In a loft conversion, check the sloped ceiling too, since a bed this wide limits which wall it can sit against.
Will I feel my partner move on a super king Emma Original?
Less than on any smaller size. The 5-zone pocket springs respond individually rather than as one unit, which limits motion transfer, and at this width your partner's side of the bed is simply further from yours. If disturbed sleep is the reason you're upgrading, the extra distance does more than any foam layer could.
Where can I buy the Emma Original in a super king?
Compare the retailers listed on this page; the prices shown are updated as retailers change them, so it's worth checking more than one before you commit. Bear in mind that super king bedding is sold by fewer shops than double or king sizes, and you'll need a 260 x 220cm duvet.
