Key benefits
- Space to turn over: At 30cm wider than the UK single, it lets you lie on your side with your knees drawn up without an elbow hanging off the edge.
- Fits rooms a UK double would crowd: We suggest at least 2.4m x 2.8m, so it suits box rooms and attic bedrooms where a wider bed would leave no space to walk round.
- A middle-ground feel for guests: The medium feel, which Hyde & Sleep says suits all sleep positions, means a visitor who sleeps differently from you is unlikely to find it too extreme.
- Bedding is simple to buy: Fitted sheets labelled small double or 4ft fit it, and a standard double duvet covers it, so you won't need to hunt for unusual sizes.
- No trade-off in build: You get the same 27cm of memory foam, Serene foam and micro springs as the larger sizes, so choosing a narrower bed doesn't mean a thinner mattress.
This size suits you if...
You sleep alone but feel hemmed in on a single, your bedroom is compact or has a sloping ceiling that rules out a wider frame, or a guest room needs to take a visiting couple now and then rather than every night.
Consider another size if...
You share a bed every night, as the UK small double is better kept for occasional couples. We'd recommend the UK double instead, which gives 67.5cm each and needs at least 2.6m x 2.8m.

FAQ's
Is the Hyde & Sleep Lime Hybrid UK small double big enough for two adults?
For a weekend visit, yes. For nightly sharing it gets tight, and the medium feel won't change that. The UK double is 15cm wider and gives 67.5cm each for two sharing, so couples who sleep together every night are usually happier on the UK double.
What room size do I need for a UK small double mattress?
We suggest at least 2.4m x 2.8m. That allows space to walk past the bed and open a wardrobe. In an attic bedroom with a sloping ceiling, measure the floor where you can actually stand upright, as the usable space is often smaller than the room itself.
Is a UK small double long enough for a tall person?
It measures 190cm long, the same as the UK single and UK double. The UK king and UK super king are 10cm longer, so if your feet already reach the end of a 190cm bed, sizing up to one of those is the only way to gain length with this mattress.
Should a teenager move from a single to a small double?
If they've started sprawling, the UK small double adds 30cm of width with no extra length, so it often fits along the same wall as their old bed. Measure the gap between the bed and the door first, then compare the retailers listed on this page.
What sheets fit the Hyde & Sleep Lime Hybrid in a UK small double?
Look for fitted sheets sold as small double or 4ft, paired with a standard double duvet. The mattress is 27cm deep, so deep-fitting sheets are the safer choice, as shallow ones can ping off the corners when you turn over.
