Layer Details
- Fits where other sizes will not: At 90cm wide the UK single leaves floor space free in a child's room that also has to hold a wardrobe, desk and toy storage.
- Pocket springs for growing sleepers: Each spring compresses independently, which means a lighter body still sinks in enough to be supported rather than lying on top of a stiff surface.
- Works for shared kids' rooms: Two UK singles plus a walkway will fit rooms where a larger bed would swallow the space, so siblings sharing each keep their own mattress.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
- Sensible for a spare room that earns two uses: In a study that doubles as guest space, a UK single takes up little enough floor to leave the desk usable all week.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, you're a single adult in a compact room or first flat where a frame is already provided, or you're furnishing a spare room that has to work as an office most of the time. The UK single fits almost anywhere a bed can go, and it's the easiest size to bed out cheaply.
Consider another size if...
You're an adult who shares the bed, even occasionally, or you simply want space to spread out. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Is the Graphite Arthur UK single suitable for a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames, so the width and length will fit. The catch is depth: Arthur Sleep doesn't publish one for this mattress, and raised frames usually have a maximum mattress depth for the guard rail to work safely. Check with the retailer before ordering for a raised frame.
Is a UK single big enough for an adult?
For one adult sleeping alone, yes. At 90cm wide and 190cm long it's the standard UK one-person size, and it suits most adults up to around 6ft comfortably. If you're taller, or you like room to sprawl, the UK king runs 200cm long, 10cm longer than the UK single, though it needs a far bigger room.
Will two UK singles fit in one children's room?
Often, yes. Each mattress is 90cm wide, so two beds plus a walkway between them is realistic in a reasonable-sized shared room, where a single larger bed would dominate the floor. For one UK single we suggest at least 2.1m x 2.8m; measure your own room with both beds and the gap in mind.
What room size do I need for a single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which is our own guidance rather than the brand's. That covers the mattress plus enough room to get in and out and open drawers. Most UK box rooms and loft conversions clear it, and the narrow 90cm footprint helps where a sloped ceiling limits where the bed can sit.
Is the UK single worth it over the UK small double for a teenager?
The UK single suits most teens, and its bedding is cheaper and easier to find. That said, the UK small double is 30cm wider at the same length, so if the room allows at least 2.4m x 2.8m and your teenager is nearly adult-sized, the extra width may see them through into their twenties.
