Layer Details
- Real room for one: At 120cm across, the UK small double is 30cm wider than the UK single, which means you can roll over and starfish without an elbow off the edge.
- Fits where a double can't: It's 15cm narrower than the UK double, often the difference between a door that clears the bed frame and one that doesn't.
- Same length as a single: Both share the 190cm length, so upgrading from a UK single widens your bed without pushing the footboard closer to the wall.
- Works for occasional sharing: Two guests can manage a night or two comfortably enough, which makes this size a sensible pick for a spare room the boxtop can make feel welcoming.
- Standard 4ft bedding: The UK small double is a standard British size, so fitted sheets are easy to find and a normal double duvet drapes generously over it.
This size suits you if...
You sleep alone and have outgrown a single, but your room can't spare the width a full double demands. Or you're furnishing a box room, loft conversion or studio where every centimetre beside the bed matters. It also suits a guest room that hosts the occasional couple rather than anyone nightly. Allow at least 2.4m x 2.8m of floor space for this size.
Consider another size if...
You share the bed every night, in which case 120cm will feel tight over time. We'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m for it.

Is a UK small double big enough for a couple every night?
For nightly sharing, we'd say no. The UK small double is 120cm wide, and while the Boxtop's cushioned top layer helps with comfort, width is width. It suits couples for occasional guest room stays. If two of you will sleep on it every night, the UK double at 15cm wider is the better buy, and it's the same length.
What room size do I need for the Kaymed Gel Pocket 2500 in a UK small double?
We suggest allowing at least 2.4m x 2.8m. That gives you space to walk around the bed and open the door and wardrobes without a squeeze. This is our own guidance rather than Kaymed's, so measure your room, including any sloping ceilings in a loft conversion, before you order.
Is the UK small double a good upgrade from a single?
Yes, if the room allows it. You gain 30cm of width over the UK single while the length stays identical at 190cm, so the bed grows sideways rather than into your walking space. That makes it a popular move for a teenager who has outgrown a single but whose room can't take a full double.
Does a small double Kaymed Boxtop fit standard bedding?
Yes. The 4ft small double is a standard UK size, so fitted sheets marked small double or 4ft are stocked widely. Most people pair it with a standard double duvet, which overhangs nicely on a 120cm mattress. One thing to check: boxtop mattresses tend to sit deep, so look for deep-fitted sheets.
