Layer Details
Quilted top layer
A 1cm layer of memory foam quilted into the top of the cover. It adds a thin, soft feel under you without making the surface sink.
Soft foam layer
A 2cm layer of soft foam sits beneath the cover. It adds a little more cushioning between you and the springs, which helps keep the medium feel comfortable.
Pocket springs
800 individual pocket springs, each encased in its own cloth pocket and moving independently. Each spring responds on its own, so the mattress follows your body more closely and you feel less of a partner's movement.
Non-slip base fabric
A non-slip fabric underside cover. It helps the mattress stay put on your bed base rather than shifting about.

Key benefits
- Room to spread out alone: At 30cm wider than the UK single and the same length, it gives someone who has outgrown a single bed proper elbow room without needing a bigger room.
- Fits tighter bedrooms: Being 15cm narrower than the UK double, it can leave enough clearance for a box room door to swing open or a chest of drawers to pull out fully.
- Fine for a couple now and then: Two people can share it for a short stay, and the individually moving springs mean one guest turning over disturbs the other a little less.
- Easier in a loft conversion: Under a sloping ceiling, the narrower UK small double can sit further from the low wall, leaving you somewhere to stand as you get in and out.
- Simple to dress: Because 4ft is a standard UK width, frames and small double fitted sheets are easy to buy, and a standard double duvet fits comfortably over the top.
This size suits you if...
You sleep alone but like to stretch out, your bedroom is a box room or loft conversion where every bit of floor counts, or you're kitting out a guest room that only hosts a couple now and then.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest a room of at least 2.6m x 2.8m for the UK double.

FAQ's
What room size do I need for a SleepSoul Comfort 800 small double?
We suggest allowing at least 2.4m x 2.8m for the UK small double. That leaves space to walk around the bed and open doors in a smaller bedroom. If your room is tighter still, we suggest at least 2.1m x 2.8m for the UK single.
Is the SleepSoul Comfort 800 small double big enough for a couple?
For occasional stays, yes. For every night, most couples will want more room, and the UK double gives 67.5cm each for two sharing. The individual springs help cut down on movement from a restless partner, but they can't add width.
Will a SleepSoul Comfort 800 small double fit a 4ft bed frame?
Yes. The UK small double is 120 x 190cm, which is 4ft x 6ft 3in, the standard UK 4ft size. Measure the inside of your frame before ordering, as some older or handmade frames run slightly off standard.
Is a small double Comfort 800 a good upgrade for a teenager?
If your teenager has outgrown a single but the bedroom can't give up much floor, it's a sensible step. It adds 30cm of width over the UK single at the same length. The medium feel suits most growing sleepers, although a very tall teenager may prefer the UK king, which is 10cm longer.
Does the SleepSoul Comfort 800 small double work in a loft conversion?
Often, yes. Being 15cm narrower than the UK double, it can sit further from a sloping ceiling, giving you headroom beside the bed. Check the height of the low wall against the mattress and frame first, because SleepSoul doesn't publish a depth for this mattress.
