Key benefits
- Space to spread out on your own: At 30cm wider than the UK single, the UK small double lets one adult sleep diagonally or flung out without an arm dropping off the edge.
- Keeps a compact room usable: The UK small double is 15cm narrower than the UK double, which can decide whether a box room door still swings clear of the bed frame.
- Easier into a loft conversion: Because the mattress comes rolled, carrying it up a steep loft staircase or round a tight landing is far simpler than handling a rigid 4ft mattress.
- Fine for the odd shared night: Two adults can manage a weekend visit on the UK small double, although couples sharing every night will want the extra width of the UK double.
- Bedding is simple to buy: 4ft is a standard UK width, so fitted sheets labelled small double are easy to find, and a standard double duvet gives generous overhang.
This size suits you if...
You sleep alone and have outgrown a single but can't spare the floor for a full double, or you're furnishing a compact guest room where couples stay only now and then.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for that room.

FAQ's
Will a Hyde & Sleep Hybrid Lime small double fit in a box room?
For the UK small double we suggest a room of at least 2.4m x 2.8m. That leaves space to walk round the bed and open the door without catching the frame. If your box room is tight, measure where the door swings first, then compare the retailers listed on this page.
Can two adults sleep on a UK small double Hybrid Lime every night?
It works for occasional stays, such as guests over a weekend, but nightly sharing tends to feel cramped. If you share every night, the UK double gives 67.5cm each and needs a room of at least 2.6m x 2.8m.
Is the UK small double Hybrid Lime long enough for a tall person?
The UK small double is 190cm long, the same length as the UK single and UK double. If you're tall and your feet already reach the end of a standard bed, the UK king is 10cm longer, though we suggest at least 2.7m x 2.9m of room for it.
Should my teenager move from a single to a small double Hybrid Lime?
It's a sensible step up when a teenager has outgrown a single. The UK small double is 30cm wider and the same length, so you gain width without losing extra floor at the foot. We suggest at least 2.4m x 2.8m, compared with 2.1m x 2.8m for the UK single.
What size sheets fit a Hyde & Sleep Hybrid Lime small double?
Look for fitted sheets sold as small double or 4ft, and pair them with a standard double duvet. Hyde & Sleep doesn't publish a depth for this mattress, so check the brand's own guidance or choose a deep-pocket fitted sheet to be safe.
