Layer Details
- Real space for one: The UK small double is 30cm wider than the UK single, which means a solo sleeper can shift position freely without an elbow off the edge.
- Fits rooms a double cannot: It's 15cm narrower than the UK double, often the difference between a door that clears the bed frame and one that doesn't.
- Standard length: At 190cm long, the same as the UK single and UK double, it suits most adults, although very tall sleepers may want the extra 10cm a UK king offers.
- Easy bedding and frames: 4ft is a standard UK size, so fitted sheets and frames are simple to find, and a standard double duvet covers it comfortably.
- A practical guest room size: Couples can share for the occasional night, so a spare room or holiday let gets flexibility without giving up walking space.
This size suits you if...
You sleep alone most nights and have outgrown a single but can't spare the floor space a double demands, your room is a box room, loft conversion or studio where 15cm of width decides whether the layout works, or you're furnishing a guest room or small let where couples stay occasionally rather than every night. Allow at least 2.4m x 2.8m of floor space.
Consider another size if...
You share the bed every night and can fit a wider frame, since 120cm is tight for two long term. We'd recommend the UK double instead, which adds 15cm of width at the same length.

Is a UK small double big enough for two adults every night?
For occasional nights, yes. For nightly sharing, 120cm across is a squeeze: each of you gets less width than you'd have on a UK single. If your room allows it, the UK double of this mattress adds 15cm of width at the same 190cm length, which makes a real difference night after night.
Will the small double Highgrove Kingston fit in a box room?
Often, yes, and that's the point of the size. At 120 x 190cm it's 15cm narrower than a UK double, which frequently decides whether the door still clears and there's a walkway beside the bed. We suggest a room of at least 2.4m x 2.8m to live with it comfortably.
How much bigger is the UK small double than the UK single?
It's 30cm wider, at 120cm against the single's 90cm, and the two are exactly the same 190cm length. That extra width is why it suits a teenager or solo adult who has outgrown a single: you get genuine stretching room without stepping up to a full double's footprint.
Is this size a good choice for a guest room?
Yes, it's one of the most practical guest room sizes. A couple can share it for a weekend stay, a solo guest gets plenty of space, and the room keeps more floor than a double would allow. Just be aware Highgrove doesn't publish firmness or construction details, so you're buying the size on firmer ground than the feel.
What bedding do I need for this size?
Small double, or 4ft, fitted sheets, which are a standard UK size and easy to find. For the top layer, a standard double duvet works well, giving a comfortable overhang on each side. You don't need speciality bedding for this size the way you might for less common dimensions.
