Layer Details
- Damask cover. A finely woven, durable fabric that feels soft to the touch and doesn't retain heat. That matters on a firm mattress, where you sleep more on the surface than in it.
- Silk and polyester fibre blend. A blend of silk and polyester fibres sits beneath the cover for extra comfort and breathability. It takes a little of the edge off the firm feel.
- Soft white fibres. Dual density fibres, plush on one side and dense on the other, deliver the firm comfort while increasing airflow through the mattress. Better airflow means less heat building up overnight.
- Pocket springs. 1000 individual springs, each encased in its own fabric pocket, respond to your movements independently. You get support where you press down without disturbing the rest of the bed.

- Real room for one: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a solo sleeper can sprawl, roll and starfish without hanging over an edge.
- Fits compact double bedrooms: It's 15cm narrower than the UK double, so it slots into box rooms, studios and loft conversions where a 4ft 6in frame would block the door or the walkway.
- Firm support across the full width: The 1000 pocket springs give the same responsive, firm support at the edges as the middle, useful when one sleeper uses the whole 120cm surface.
- Movement stays where it happens: Each spring works independently, so if a partner joins you for the occasional night, their turning is less likely to travel across the narrower shared surface.
- Standard UK sizing: 4ft is a standard UK size, so small double fitted sheets and frames are easy to find, and a normal double duvet drapes generously over it.
This size suits you if...
You sleep alone most nights and have outgrown a UK single, but your room can't spare the width a UK double takes, or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly. It also suits a teenager moving up from a single in a room where floor space is tight. Allow at least 2.4m x 2.8m of room.
Consider another size if...
You share the bed every night. At 120cm across, two adults on a firm surface will feel cramped, and the pocket springs can't fix a lack of width. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room.

Is a small double big enough for one adult on the Relyon Leano 1000?
Comfortably, yes. The UK small double is 120 x 190cm, 30cm wider than the UK single at the same length, so a solo adult has plenty of space to move around. Because the Leano is a genuinely firm mattress, you sleep on the surface rather than sinking in, and the extra width makes changing position easier.
Can a couple share the Relyon Leano 1000 in a small double?
For the odd night, yes, which makes it a reasonable guest room choice. For every night, we wouldn't suggest it: 120cm is tight for two adults, and on a firm mattress you can't sink towards the middle to make room. Regular sharers should look at the UK double, which gives 67.5cm each.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m for a UK small double, which leaves enough space to walk round the bed and open drawers or a wardrobe. That's our own guidance rather than Relyon's. If your room is smaller than that, measure carefully before ordering, paying attention to door swing.
How much smaller is the small double than the Leano's other sizes?
The UK small double is 15cm narrower than the UK double and the same length. Against the UK king it's 30cm narrower and 10cm shorter, and against the UK super king it's 60cm narrower and 10cm shorter. Going the other way, it's 30cm wider than the UK single, again at the same length.
Where can I buy the Relyon Leano 1000 in a small double?
Compare the retailers listed on this page. The prices shown here are live and updated as retailers change them, so it's worth checking back if you're deciding over a few days. Stock in the UK small double can move separately from the other sizes, since 4ft is a less common size than the UK double or UK king.
