Layer Details
- Cotton sleep surface. A responsibly sourced cotton sleep surface that is naturally fire-resistant. It's the layer you'll actually feel, soft and breathable against the skin.
- Cotton. A cotton filling that helps regulate body temperature, which means less overheating on warm nights. It also adds natural comfort and a touch of extra support.
- Solotex™. A recycled fibre that is fully breathable, so air can move through the mattress rather than getting trapped. A quietly sustainable choice too.
- ReActive™ 6-Turn Pocket Springs. Each spring has six turns and works independently, sensing the support you and your partner need and spreading downward pressure smoothly. In practice, that means consistent spinal support and less partner disturbance.
Layer details from mattressnextday.co.uk product page, September 2026.
- Room to stretch, alone: At 120cm wide, a solo sleeper gets 30cm more width than a UK single, which means space to shift position freely on a firm surface that resists rolling.
- Fits where a double won't: Being 15cm narrower than the UK double, it can be the difference between a door that clears and one that doesn't in a box room or studio.
- Firm support at this width: The ReActive 6-turn pocket springs respond to your weight independently, so even sleeping alone on 120cm you get consistent spinal support edge to edge.
- Practical for guest rooms: A couple staying the odd night can share a small double comfortably enough, making this a sensible choice for a spare room that hosts occasionally.
- Easy to dress: The 4ft small double is a standard UK size, so fitted sheets and frames are simple to find, and a standard double duvet works fine.
This size suits you if...
You're a solo adult, or a teenager who has outgrown a single, and you want proper stretching room without giving up the floor space a full double demands, or your bedroom is compact and 15cm of width decides whether the room still functions, or you're furnishing a guest room where couples stay occasionally rather than nightly.
Consider another size if...
You share the bed every night and 120cm feels tight for two adults on a firm mattress. We'd recommend the UK double instead, which is 15cm wider; allow at least 2.6m x 2.8m for it.

Is a small double big enough for the Hypnos Premier Ortho Superb to suit a couple?
For occasional nights, yes. Two adults can share 120cm of width, and the ReActive 6-turn pocket springs work independently, so one person's movement is less likely to disturb the other. For nightly sharing, though, a firm mattress at this width leaves little room to spread, and we'd point couples to the UK double instead.
What room size do I need for a small double Hypnos Premier Ortho Superb?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers or a wardrobe. If your room is smaller than that, a UK single may suit it better; we suggest at least 2.1m x 2.8m for the UK single.
How much bigger is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. That extra width is the whole point for a solo sleeper: room to change position without reaching the edge, which matters on a firm mattress like this one where you sleep on the surface rather than sinking into it.
Will the small double fit through a loft conversion or narrow doorway more easily than a double?
It has a better chance, being 15cm narrower than the UK double, though the mattress is 27cm deep and pocket sprung, so it won't fold or squash the way foam does. Measure your stairwell and door frames against 120 x 190cm before ordering, particularly for lofts with restricted headroom beside the bed.
