Layer Details
- Fits most UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which many second bedrooms and older terraced houses can manage where a UK king would struggle.
- Pocket springs matter more when you share: Each spring moves independently, which means a partner turning over on 135cm of shared width disturbs you less than an open coil would.
- 67.5cm each for two people sharing: That's the standard couples' allowance, comfortable for most pairs, although two broad-shouldered sleepers may feel it a little snug.
- Room for bedside tables both sides: At 135cm wide, the UK double usually leaves space either side for tables and walking room, something worth checking before you consider sizing up.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet are stocked everywhere at every price, useful if you're furnishing a whole home on a stretched budget.
This size suits you if...
You share the bed most nights and your room sits around the typical UK size, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner. It also makes sense if you're kitting out a first flat or a guest room for visiting couples and want the medium firm support of the Emperor Arthur without a king-sized footprint.
Consider another size if...
You and your partner both like room to sprawl and your bedroom measures at least 2.7m x 2.9m. In that case we'd recommend the UK king instead: it's 15cm wider and 10cm longer than the UK double.

How much space does each person get on the Emperor Arthur UK double?
Two people sharing the UK double get 67.5cm each. That's the long-standing UK standard for couples and works well for most, though the pocket spring construction helps here: springs respond individually, so you feel less of a partner's movement across that shared width than you would on an open coil mattress.
How much bigger is the UK king Emperor Arthur than the UK double?
The UK double is 15cm narrower and 10cm shorter than the UK king. That extra width is noticeable for couples, but it needs the room to match: we suggest at least 2.7m x 2.9m for the UK king, against 2.6m x 2.8m for the UK double. Measure with your wardrobe and drawers in place before deciding.
Will the Emperor Arthur UK double fit in a smaller bedroom?
We suggest allowing at least 2.6m x 2.8m, which covers most UK bedrooms including many second bedrooms and first flats. That leaves enough space to open drawers and walk round the bed. If your room is tighter than that, this mattress isn't made in a UK small double or single, so measure carefully before committing.
Does the Emperor Arthur mattress come in a UK small double or single?
No. The UK double, at 135 x 190cm, is the smallest size Arthur Sleep makes this mattress in, with the UK king and UK super king above it. If you need a narrower bed for a child's room or a compact guest room, you'll need a different mattress rather than a smaller Emperor Arthur.
Is the Emperor Arthur UK double a good choice for one person?
Yes, if you like room to stretch out. A solo sleeper gets the full 135cm width, generous compared with a single, and the medium firm feel suits most sleeping positions. Lightweight side sleepers may find it slightly solid at the shoulder and hip, which is a firmness point rather than a size one.
