The Graphite Arthur from Arthur Sleep is a pocket spring mattress, which means the springs are individually wrapped in fabric pockets so they respond to your body separately rather than moving as one unit.

Key benefits
- Real room for one: The UK small double is 30cm wider than the UK single, which means a solo adult can change position freely without a hip or shoulder reaching the edge.
- Fits compact rooms: At 15cm narrower than the UK double, this size can leave a clear walkway in a box room or studio where a 4ft 6in bed would block the door.
- Pocket springs suit occasional sharing: Individually pocketed springs respond to each body separately, so if a couple uses this bed for the odd night, one person turning over disturbs the other less.
- Standard 4ft size: The small double is a standard UK size, so frames and fitted sheets are easy to find, and a normal double duvet covers it comfortably.
- Sensible room allowance: We suggest a bedroom of at least 2.4m x 2.8m, which brings loft conversions and small second bedrooms into play for this mattress.
This size suits you if...
You're a solo adult who has outgrown a single but can't spare the floor space a double demands, you're furnishing a small second bedroom or holiday let where guests might occasionally share, or you're downsizing and the bed now has to fit the new room rather than the old one. The 120 x 190cm footprint is the compromise that keeps a compact bedroom usable.
Consider another size if...
You share the bed every night, since 120cm across two adults feels tight over time. We'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m of room for it.

FAQ's
Is a small double big enough for the Arthur Sleep Graphite Arthur to sleep two?
For occasional nights, yes. The pocket spring construction helps here, because each spring compresses independently and limits how much movement crosses the bed. For nightly sharing, though, 120cm of width is a squeeze for two adults, and the UK double or UK king of this mattress would serve a couple better.
What are the dimensions of the Graphite Arthur small double?
It measures 120 x 190cm, which is 4ft x 6ft 3in. That makes it 30cm wider than the UK single and 15cm narrower than the UK double, with all three sharing the same 190cm length. Arthur Sleep doesn't publish a depth for this mattress, so check the retailer listing if clearance under a window sill matters.
What room size do I need for a small double mattress?
We suggest at least 2.4m x 2.8m for a UK small double, which allows space to walk around the bed and open drawers. That's our guidance rather than the manufacturer's. If your room is smaller than this, the UK single may keep the space workable, though you lose 30cm of bed width.
Should I choose the small double or the UK double Graphite Arthur?
It comes down to your room. The UK small double is 15cm narrower than the UK double, and that 15cm often decides whether a door clears or a wardrobe still opens. If your room comfortably meets 2.6m x 2.8m, the UK double gives a couple more space; below that, the small double keeps the room liveable.
What bedding fits the small double Graphite Arthur?
You'll need small double (4ft) fitted sheets, which are a standard UK size and widely stocked. A regular double duvet works well on top, giving a little extra drape on each side. There's no need for specialist bedding, which keeps ongoing costs ordinary for this size.
