Layer Details
- Fits a child's room with space left over: At 90cm wide it leaves room for a wardrobe, desk and toy storage in bedrooms where every foot of floor matters.
- Full adult length: The 190cm length is the same as a UK double, so a teenager won't outgrow it the way they outgrow the bed frame.
- Quiet for shared rooms: Pocket springs move independently, which means one restless child in a shared room is less likely to be heard creaking through the night.
- A guest bed people remember kindly: Two UK singles in a spare room sleep visiting couples and solo guests alike, and Hypnos build quality is rarely what guests expect from a spare bed.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for one sleeper: a child moving up from a cot bed, a teenager, or an adult in a compact room or first flat. It also suits a spare room that doubles as an office, where a 90cm footprint leaves the desk usable, or a guest room taking two beds side by side with a walkway between them.
Consider another size if...
Two of you will share the bed, or you're a solo adult who likes to spread out. We'd recommend the UK double instead: it's 45cm wider, the same length, and we suggest a room of at least 2.6m x 2.8m for it.

Is a UK single Hypnos Legacy 3 big enough for an adult?
For one adult, yes, provided you sleep fairly still. At 90 x 190cm it's the standard UK one-person size, and the length matches a UK double. Broad-shouldered sleepers or anyone who moves around a lot may find 90cm a little confining, in which case the UK double gives you 45cm more width.
Will the Hypnos Legacy 3 single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint is the standard bunk and mid sleeper size, so width and length should be fine. Depth is the thing to check: raised frames often set a maximum mattress height for the guard rail, and Hypnos doesn't publish a depth on the listing we reviewed, so confirm it with the retailer first.
What room size do I need for a UK single Hypnos Legacy 3?
We suggest at least 2.1m x 2.8m of floor space. That's our own guidance, not the manufacturer's, and it allows you to walk round the bed and open drawers. In a child's room competing with a desk and wardrobe, or under the slope of a loft conversion, the 90cm width is the easiest of any size to place.
Is the Hypnos Legacy 3 in a single a good choice for a child or teenager?
The medium tension suits most sleepers and the pocket springs follow the body rather than pushing back, which works across a wide range of ages and weights. It's a premium spend for a child's room, but the full adult length means it can last from around eight or nine right through the teenage years.
Should a guest room get one Hypnos Legacy 3 single or a double?
Two UK singles suit rooms that host solo guests as often as couples, since each sleeper gets their own bed and the pocket springs keep movement to one side. If your guests are usually couples and the room only takes one bed, the UK double is 45cm wider than the UK single and the same length.
