Layer Details
- 75cm of width each: Two people sharing get 75cm each, which means you can turn over or stretch out without negotiating for territory in the small hours.
- Pocket springs across a wider bed: Individually pocketed springs respond to each sleeper separately, and at king width there is enough distance between you for that isolation to be felt properly.
- Extra length for taller sleepers: At 200cm long, the UK king gives anyone approaching six foot room to lie flat without their feet meeting the end of the bed.
- A real step up from a double: The UK king is 15cm wider and 10cm longer than the UK double, a difference you notice every night rather than only on paper.
- Fits more rooms than a super king: The UK king is 30cm narrower than the UK super king, so it delivers couple-friendly space without demanding an unusually large bedroom.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially if one of you gets up hours before the other and you want their movement to register as little as possible. It also makes sense if either of you is approaching six foot, since the 200cm length removes the feet-over-the-edge problem, or if a dog has quietly become a permanent third occupant.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest for a UK king, which is easily done in a new build master once wardrobes go in. We'd recommend the UK double instead, where we suggest at least 2.6m x 2.8m.

Is the Graphite Arthur in a UK king good for couples?
It is a reasonable fit. The UK king gives 75cm of width each, and the Graphite Arthur's pocket springs move independently, so one person shifting position transfers less motion across the bed. Arthur Sleep doesn't publish a firmness rating for this model, so lighter or heavier partners should treat the retailer's trial as the real test of comfort.
What room size do I need for the Graphite Arthur UK king?
We suggest at least 2.7m x 2.9m for a UK king, which leaves enough space to walk around the bed and open drawers. Measure carefully in a new build master bedroom: they often look generous empty but tighten quickly once fitted wardrobes are in. If your room is smaller, the UK double needs at least 2.6m x 2.8m by our guidance.
Should I get the Graphite Arthur in a king or a super king?
The UK king is 30cm narrower than the UK super king, and both are the same length, so sizing up buys width alone. If your room can meet the 3m x 2.9m minimum we suggest for a UK super king, and restless sharing is your main complaint, the wider bed helps. Otherwise the UK king serves most couples well.
Is a UK king long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than the UK double, and that length is often the real reason taller sleepers upgrade. Someone around or just over six foot can lie fully flat with room to spare. If you are well beyond that height, no standard UK size adds further length, since the UK super king is the same 200cm.
Where can I buy the Graphite Arthur mattress in a UK king?
Availability for this model is narrower than most, so the simplest route is to compare the retailers listed on this page, where prices are updated as retailers change them. The UK king sits in the middle of the range Arthur Sleep offers for the Graphite Arthur, which runs from the UK single up to the UK super king.
