Key benefits
- Space for one to spread out: At 30cm wider than a UK single, you can sleep diagonally or starfish, which helps restless solo sleepers who keep meeting the edge of a narrower bed.
- Fits rooms a double would crowd: Being 15cm narrower than a UK double can decide whether a wardrobe door still opens fully or a bedside table squeezes in beside the frame.
- Handles the odd shared night: Two people can share it for a weekend visit, so a spare room can host a couple without giving the floor over to a bigger bed.
- Easy to dress: Small double fitted sheets suit this 4ft mattress and a standard double duvet covers it, so finding bedding in UK shops is straightforward.
- Deep, so check your frame: At 31cm deep this mattress sits high, which means a 4ft frame with tall sides or a low loft ceiling may need a second look.
This size suits you if...
You sleep alone and like room to roll over, or a teenager has outgrown their single but the bedroom can't spare much more floor. It also fits if you're furnishing a guest room where couples stay now and then rather than every night.
Consider another size if...
You and a partner will share it every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
What size is a Millbrook Wool Sublime Pocket 4000 small double in feet?
The UK small double version measures 4ft x 6ft 3in, which is 120 x 190cm. It's a standard UK size, so a 4ft bed frame or divan base should take it. Do check how high your frame's sides sit, as the mattress is 31cm deep.
What room size do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk round the bed and open doors. In a box room or loft conversion, measure where the door swings and where the ceiling slopes before you order.
Can two adults sleep on a small double Millbrook Wool Sublime Pocket 4000?
For occasional stays, yes, and many guest rooms use a UK small double for exactly that. For nightly sharing it's tight, because it's 15cm narrower than a UK double. Couples who share every night usually sleep better on the UK double or larger.
Is a small double big enough for a teenager?
For most teenagers, yes. It's 30cm wider than a UK single and the same length, so the extra room is in width rather than legroom. Taller teens may prefer the UK king, which is 10cm longer, though it needs a room of at least 2.7m x 2.9m.
Small double or double for a single person?
If you sleep alone, the UK small double gives plenty of width and keeps more floor clear. Choose the UK double if your room comfortably allows at least 2.6m x 2.8m and you'd like extra space for guests.
