Layer Details
- High Density Memory Foam. A 2.5cm layer of high density memory foam that shapes around your body to relieve built-up pressure. You'll feel a gentle cradling at your hips and shoulders rather than a deep sink.
- Reflex Foam. The 15.5cm reflex foam layer responds to changes in movement or weight, tailoring support to the places that need it most. In practice, that means a stable, springy base that stops you feeling stuck in the mattress.

- 90cm each for two sharing: With 90cm each for two people sharing, a partner who turns all night becomes far easier to sleep through, because distance does what no comfort layer can.
- Room for the whole household: When a child pads in at 3am, or the dog treats the bed as routine, the extra width means nobody ends up clinging to the edge.
- Foam limits motion transfer: Memory foam absorbs movement rather than bouncing it across the bed, and at this width the combination makes a fidgety sleeper almost undetectable.
- Lighter to manoeuvre than most super kings: At 18cm deep, this is a slimmer build than many foam mattresses, which makes a mattress this wide noticeably easier to flex around stairs and landings.
- Fills a large master properly: In a period property or a generous new build master, a UK king can look undersized against the wall; the UK super king sits in proportion.
This size suits you if...
You share the bed every night and want the most space a standard UK size offers, your sleep is regularly interrupted by a restless partner or visiting children, or your bedroom is large enough that a UK king would look lost in it. We suggest allowing at least 3m x 2.9m of floor space, so this size rewards a genuinely big room.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for the UK super king, or your landing and door swing make a 180cm wide mattress a struggle. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

How much bigger is a super king than a king size mattress?
The UK super king is 30cm wider than the UK king, and both are the same 200cm length. That extra width all goes into personal space: 90cm each for two people sharing, which is the difference between feeling a partner turn over and barely noticing it.
Will the Bodyshape Vitality super king fit up my stairs?
It should be more manageable than most. At 18cm deep it's slimmer than many foam mattresses, and foam flexes in a way a sprung mattress won't, which helps on tight landing turns. Even so, measure your stairwell, door swing and any awkward corners before ordering a 180cm wide mattress.
Is the Bodyshape Vitality super king good for couples with children who come in at night?
It's one of the better setups for it. The 180cm width means a small visitor can squeeze in without pushing either adult to the edge, and memory foam absorbs their wriggling rather than transmitting it. The slim 2.5cm comfort layer does mean a heavier household pile-up will reach the firmer base sooner.
Is a super king memory foam mattress worth it for a restless partner?
Width and foam are the two things that genuinely help, and this size gives you both. With 90cm each, most turning happens too far away to disturb you, and foam damps whatever movement is left. If broken sleep is your main complaint, sizing up usually does more than any upgrade in comfort layers.
What room size do I need for the Bodyshape Vitality in a super king?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels comfortable, with space to walk round both sides and open wardrobes. In a loft conversion, check the slope too: a 180cm wide bed limits which wall it can sit against. If that's tight, the UK king needs at least 2.7m x 2.9m.
