Layer Details
- 90cm each when sharing: Two people get 90cm each, which means a partner who shifts position all night is simply further away and easier to sleep through.
- Pocket springs suit the extra width: Each spring is wrapped in its own fabric pocket and moves independently, so movement on one side of a 180cm bed barely travels across.
- Space for night-time visitors: If children or a large dog end up in the bed most nights, this size means everyone still gets a usable share rather than someone clinging to the edge.
- Fills a large master properly: In a period property or generous new build master, a UK king can look undersized against the wall; the 6ft x 6ft 6in footprint holds its own.
- Check the route in first: At 180cm wide this is a big single unit, so measure your stairs, landing turns and door swing before ordering, as it does not split into halves.
This size suits you if...
You share the bed every night and one of you is a genuinely restless sleeper, because at this width distance does more than any comfort layer could. It also suits you if children or pets join you regularly, or if your bedroom is large enough that a UK king would look lost. Allow at least 3m x 2.9m of floor space.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m we suggest for a UK super king, or your stairs and landing make a 180cm mattress impractical. The UK king is 30cm narrower and the same length, and we suggest at least 2.7m x 2.9m for it.

How much space do two people get on the Graphite Arthur super king?
90cm each for two people sharing, which is the same width per person as a UK single. Combined with pocket springs that respond to each body separately, that gap makes a fidgeting partner far easier to ignore than on a smaller mattress.
What room size do I need for the Graphite Arthur in a UK super king?
We suggest at least 3m x 2.9m, which is our guidance rather than the brand's. That leaves walking room on both sides and space for bedside tables. If you're squeezing it into a smaller room, the UK king needs at least 2.7m x 2.9m by our guidance and is 30cm narrower.
Will the Graphite Arthur super king fit up my stairs?
It measures 180 x 200cm and arrives as one piece, so tight landing turns and narrow doorways are the main risk. Arthur Sleep doesn't publish a depth for this model, which makes flexibility hard to judge in advance, so measure your route carefully and check with the retailer before ordering.
Is the super king a good choice if children climb in at night?
It is the size we'd point families towards. At 6ft x 6ft 6in there is enough width for a child between two adults without anyone ending up on the edge, and the pocket springs mean a wriggling visitor disturbs the rest of the bed less than a connected spring unit would.
