Key benefits
- Space for one to spread out: The UK small double is 30cm wider than the UK single at the same length, which means room to turn over and sprawl without hanging off the edge.
- Fits compact double rooms: Being 15cm narrower than the UK double, it can leave you enough floor to open a wardrobe or walk round the bed in a tight room.
- A gentle feel for lighter solo sleepers: The medium soft wool and cotton top suits a single side sleeper who wants some give, although heavier sleepers may find it a little too yielding.
- Easy to dress: Small double (4ft) fitted sheets fit it and a standard double duvet covers it, so you won't need to hunt for unusual bedding sizes.
- Works for occasional guests: Couples can manage a short stay on it, which makes it a sensible pick for a spare room nobody sleeps in nightly.
This size suits you if...
You sleep alone and want more room than a single gives, your room is too small for a 4ft 6in frame, or a partner only stays now and then, and you prefer a soft, natural-filled feel to firm support.
Consider another size if...
You share the bed every night with a partner rather than for occasional stays. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Will a Millbrook Wool Sublime Pocket 5000 small double fit in a box room?
It measures 120 x 190cm, and we suggest a room of at least 2.4m x 2.8m. That leaves space to get in and out and, in most box rooms, for the door to swing clear. If your room is tighter, measure the door arc before ordering.
Is the Millbrook Wool Sublime Pocket 5000 small double big enough for two people?
For a night or two, yes. For every night, most couples find it cramped. The UK double is 15cm wider and gives 67.5cm each for two sharing, so we'd recommend the UK double for nightly sharing, in a room of at least 2.6m x 2.8m.
Small double or single for a teenager who has outgrown their bed?
The UK small double is 30cm wider than the UK single and the same length, so a growing teenager gains sideways room rather than legroom. We suggest at least 2.4m x 2.8m for the UK small double, against 2.1m x 2.8m for the UK single, which matters in a smaller bedroom.
Is a UK small double long enough if you're tall?
The UK small double is 190cm long, the same as the UK double, so sizing up to the UK double adds width but no length. If your feet already reach the end, the UK king is 10cm longer; we suggest at least 2.7m x 2.9m for the UK king.
What sheets and duvet fit a 4ft small double mattress like this one?
Look for small double (4ft) fitted sheets, and check they're deep enough for a 32cm mattress, as some standard sheets are shallower. A standard double duvet covers the UK small double comfortably, with a little overhang at the sides.
