Layer Details
- Room to share in most bedrooms: At 135 x 190cm, the UK double fits comfortably in rooms where the UK king would leave little space to move around.
- Firm support for two: Pocket springs respond to each sleeper individually, which means one of you turning over is less likely to disturb the other.
- 67.5cm each for couples: Two people sharing get 67.5cm each, adequate for most couples, although restless sleepers may notice the limit.
- Bedside tables can stay: Allow at least 2.6m x 2.8m and most rooms will still take a table on each side, useful in older terraces and compact new builds.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are sold everywhere, so bedding stays cheap and simple to replace.
This size suits you if...
You share the bed every night and want the traditional couples' size in a room where a UK king would feel cramped, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also makes sense for a guest room that hosts visiting couples, where firm support is a safe middle-ground choice.
Consider another size if...
You and your partner both want more personal space than 67.5cm each. The UK king is 15cm wider and 10cm longer, and we'd recommend it instead if your room allows at least 2.7m x 2.9m.

Is the Ortho Arthur in a UK double a good size for a couple?
For most couples, yes. The UK double is the long-standing standard for two people sharing, giving 67.5cm each. The firm feel of the Ortho Arthur suits back and front sleepers particularly well. If either of you sleeps restlessly or is broad-shouldered, the UK king offers 15cm more width and 10cm more length.
What room size do I need for the Ortho Arthur double?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. That leaves space to open a wardrobe and walk around the bed. If you're furnishing a second bedroom or a first flat with drawers and a wardrobe to fit in, the double usually works where a UK king would dominate.
How much bigger is the double Ortho Arthur than the single?
The UK double is 45cm wider than the UK single, and both are the same length at 190cm. That extra width is the difference between a solo bed and one two people can genuinely share. Solo sleepers often size up to the double simply for the space to spread out.
Will the double fit up narrow stairs in an older house?
Arthur Sleep doesn't publish a weight or delivery format for this mattress, so check with the retailer before ordering, especially if you have a turning staircase in an older terrace or a tight new build landing. Pocket spring mattresses generally arrive flat rather than rolled, which makes stairs the main thing to measure.
Should a solo sleeper get the double or the small double?
The UK double is 15cm wider than the UK small double, and both share the same 190cm length. Sleeping alone, either gives you generous space, though the double leaves more room for a pet at the foot of the bed and a far wider choice of bedding. The small double suits rooms under our suggested 2.6m x 2.8m; we suggest at least 2.4m x 2.8m for it.
