- Proper stretching room for one: At 120cm across, the UK small double is 30cm wider than the UK single, which means a solo adult can sprawl without an arm hanging off the edge.
- Fits rooms a double overwhelms: It's 15cm narrower than the UK double, often the difference between a door that clears the bed frame and one that doesn't in a box room or loft conversion.
- A soft feel with space to use it: A soft pocket sprung mattress suits sleepers who like to sink in and shift about, and this width gives you the space to actually do that.
- Standard UK sizing: The 4ft small double is a standard UK size, so frames, fitted sheets and a normal double duvet are all easy to find.
- Same length as a single: Both the UK small double and the UK single run 190cm long, so upgrading from a single adds width without asking any more of your room's length.
This size suits you if...
You sleep alone and have outgrown a single, perhaps a teenager whose room can't spare another centimetre of floor, or an adult in a studio or small second bedroom. It also makes sense for a guest room where couples stay occasionally rather than nightly, and this soft, wool-rich mattress gives those guests a genuinely comfortable night rather than a spare-room compromise.
Consider another size if...
You and a partner will sleep on it every night, as 120cm is snug for two long term. If your room allows, we'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

Is a small double big enough for the Millbrook Wool Sublime for two people?
For occasional nights, yes, which is why it suits guest rooms well. For a couple sharing every night, 120cm is tight, particularly on a soft mattress where you both settle into the surface. If the room can take it, the UK double is 15cm wider and gives 67.5cm each; we suggest at least 2.6m x 2.8m of floor space for it.
What room size do I need for the Wool Sublime in a UK small double?
We suggest allowing at least 2.4m x 2.8m. That leaves room to walk around the bed and open the door, which is usually the deciding factor in box rooms and loft conversions. If your room comfortably exceeds that, it may be worth checking whether the UK double fits instead, using our suggested minimum of 2.6m x 2.8m.
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 exactly the same length at 190cm. In practice that means a big step up in sleeping space without the bed reaching any further into the room, which is why it's a popular upgrade for teenagers or anyone moving on from a single in a smallish bedroom.
What bedding fits the Millbrook Wool Sublime small double?
You'll need small double (4ft) fitted sheets, which are a standard UK size and easy to find, paired with a normal double duvet. That combination works because the duvet's extra width drapes over the sides. Standard double duvet covers and pillowcases are fine, so you're only buying one size-specific item: the fitted sheet.
Where can I buy the Wool Sublime Soft Pocket 11000 in a small double?
Availability for this size is more limited than for some mattresses, so it pays to check the retailers listed on this page, where prices are updated as retailers change them. Given this is a premium mattress, it's worth confirming depth and care instructions on the retailer listing before you order, as Millbrook doesn't publish full construction detail for this model.
