- Pocket springs. 800 pocket springs individually react to your natural sleeping position, which means pressure is eased where you need it rather than across the whole surface. They're spread edge to edge, so you can use the full width of the mattress without a noticeable drop-off at the sides.

- Space to spread out on your own: At 30cm wider than the UK single, it lets you sleep diagonally or on your front with arms out, without a hand dropping off the side.
- Edges you can actually use: The springs reach right to the sides, which means lying near the edge feels much like the centre, and that matters when you only have 120cm to play with.
- Fits rooms a double would crowd: We suggest allowing at least 2.4m x 2.8m, so it suits box rooms, studio flats and loft conversions where standing space beside the bed is limited.
- Copes with the odd shared night: Each spring responds on its own, so you feel less of a partner turning over, although sharing a UK small double every night is a snug arrangement.
- Easy to buy bedding for: The 4ft x 6ft 3in footprint is a standard UK size, so you'll find frames and fitted sheets on the high street without hunting for specialist sizes.
This size suits you if...
You sleep alone and have outgrown a single, your bedroom is too tight to take a UK double comfortably, or a partner or guest stays over now and then rather than every night.
Consider another size if...
You share a bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

Will a SleepSoul Balance 800 UK small double fit in a box room?
Often, yes. We suggest a room of at least 2.4m x 2.8m for a UK small double, which leaves space to get in and out. Before ordering, check how far the door swings into the room, since in a box room it's usually the door, not the wall, that decides whether 120cm of width works.
Is the Balance 800 small double comfortable for two people now and then?
For occasional stays, it's workable. The individual pocket springs reduce the jolt when the other person moves, which helps in a narrower bed. For nightly sharing it gets cramped, and the UK double gives 67.5cm each while staying the same length.
SleepSoul Balance 800 small double or double: which should I choose?
The UK small double is 15cm narrower than the UK double and the same length. If you sleep alone and your room is tight, the UK small double makes sense. If you share nightly and the room allows at least 2.6m x 2.8m, the UK double is the more comfortable pick.
Is a UK small double long enough if you're tall?
The UK small double is 190cm long, or 6ft 3in, the same length as the UK single and UK double. Very tall sleepers who find their feet near the end may prefer the UK king, which is 10cm longer, though it needs a room of at least 2.7m x 2.9m.
Should a teenager move from a single to the Balance 800 small double?
It's a sensible step up. The UK small double is 30cm wider than the UK single but the same length, so it adds room without taking more floor at the foot. We suggest at least 2.4m x 2.8m for the UK small double, compared with 2.1m x 2.8m for the UK single.
