- 90cm of width each: Two people sharing get 90cm each, which means you can both sprawl without negotiating over the middle of the bed.
- Distance plus pocket springs: The individually pocketed springs limit motion transfer, and at this width a fidgeting partner is far enough away for that to genuinely matter.
- Room for the whole household: When children wander in at 3am or a large dog treats the bed as home, 180cm of width means everyone still gets a share.
- 30cm wider than a UK king: The UK super king is 30cm wider than the UK king at the same length, a difference you feel every night you share.
- A medium feel across a big surface: The medium firmness suits sleepers who switch between back and side, so a couple with different sleeping styles can usually meet in the middle.
This size suits you if...
You share the bed every night and want enough space that neither of you notices the other, your partner is a genuinely restless sleeper and distance matters more to you than any comfort layer, or children and pets routinely join you and a smaller bed leaves someone perched on the edge. You'll also need the room for it: we suggest at least 3m x 2.9m.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest, or you sleep alone and would rather the floor space. We'd recommend the UK king instead, which is 30cm narrower at the same length and needs at least 2.7m x 2.9m.

What room size do I need for the ultra plush 4500 in a UK super king?
We suggest at least 3m x 2.9m, and that's our guidance rather than the manufacturer's. Around 3.5m x 3.2m feels more comfortable, leaving space to walk round both sides and open wardrobe doors. In a loft conversion, check the slope too: a 180cm-wide bed limits which wall it can sit against.
Is the UK super king ultra plush 4500 good for couples with a restless partner?
Yes, and this is the size where it shows most. The pocket springs respond individually rather than moving as one unit, so movement travels less across the mattress, and with 90cm of width each there's simply more distance between you. If one of you tosses and turns, the combination helps considerably.
Should I choose the ultra plush 4500 in a UK king or super king?
Both are 200cm long, so the choice is purely about width: the UK super king is 30cm wider than the UK king. If children or pets join you at night, or your partner is restless, the extra width is well spent. If your room is under 3m x 2.9m, the UK king is the safer fit at 2.7m x 2.9m.
Is this size big enough for sharing with children?
It's the best-suited standard UK size for it. At 180 x 200cm, two adults and a small visitor at dawn can usually all find room, which a UK double or king struggles to offer. The medium feel and pocket springs also mean a wriggling child disturbs the rest of the bed less than you'd expect.
What should I check before buying a mattress this wide?
Measure the route in: door swings, landing turns and tight stairwells catch out plenty of super king buyers, and Harrison Spinks doesn't publish a weight for this mattress, so check handling guidance with the retailer. Budget for bedding too, as super king sheets and a 260 x 220cm duvet cost more than king equivalents.
