Layer Details
- Real space for one: At 120cm across, you can turn over or sprawl without meeting the edge, a genuine step up from a UK single at the same 190cm length.
- Fits where a UK double will not: Being 15cm narrower than a UK double, it suits box rooms, studio flats and loft conversions where walking space beside the bed decides everything.
- Pocket springs that stay put: Each spring moves independently, which means an occasional guest sharing the bed disturbs you less than a traditional open coil would.
- Edge support matters more at 4ft: Triple Edge Protection springs mean firmer support near the sides, useful when a narrower mattress puts you closer to the edge every night.
- A modest room ask: We suggest a room of at least 2.4m x 2.8m, so a compact second bedroom or downsized main bedroom can still take it comfortably.
This size suits you if...
You sleep alone but have outgrown a UK single, perhaps a teenager whose room can't spare more floor space, or you're furnishing a guest room where couples stay occasionally rather than nightly. It also suits a downsizer whose new bedroom simply won't take a UK double, and you'd rather keep clearance around the bed than squeeze in an extra 15cm of mattress.
Consider another size if...
You share the bed every night, as 120cm is a tight long-term fit for two adults. We'd recommend the UK double instead, which is 15cm wider; allow a room of at least 2.6m x 2.8m for it.

Is the Hypnos Cotton Origins 6 small double big enough for a couple?
For occasional nights, yes. The pocket springs move independently, so you feel less of the other person's movement, which helps on a narrower mattress. For every night, 120cm across is a squeeze for two adults, and we'd point couples towards the UK double, which gives you an extra 15cm of width.
What room size do I need for a UK small double mattress?
We suggest a room of at least 2.4m x 2.8m for a UK small double. That leaves enough space to walk round the bed and open drawers or a wardrobe. In a box room or loft conversion, measure the clearance beside and at the foot of the bed before committing, as the mattress itself is 120 x 190cm.
How much wider is the UK small double than a UK single?
The UK small double is 30cm wider than the UK single, and both are the same 190cm length. In practice that means a solo adult can spread out or change position freely rather than sleeping in one lane. It's a common upgrade for teenagers who've outgrown a single but whose room can't take a full double.
Will the Cotton Origins 6 small double fit in a loft conversion or studio?
Often, yes, and that's the point of the size. At 120cm wide it's 15cm slimmer than a UK double, which can be the difference between having standing room beside the bed and not. Check the route in as well as the room: stairs, turns and door clearance matter as much as floor space with a pocket sprung mattress.
Does the edge support matter more on a small double?
Slightly, yes. On a 120cm mattress you naturally sleep closer to the sides than you would on a wider bed, so the Triple Edge Protection springs should mean the edge feels supportive rather than soft when you sit on it or sleep near it. That's the same construction across all sizes, but you notice it more here.
