Layer Details
- Cover. A cotton-rich cover sits on top. Cotton is breathable, which means it helps the sleep surface stay a little cooler than fully synthetic fabrics.
- Cushion layer. A dense cushion layer provides comfort to an already firm mattress. In practice, that means a touch of give at the surface before you reach the firmer support beneath.
- Spring unit. The spring unit forms the supportive core of the mattress. This is where the firm, orthopaedic-style feel comes from.

- Real width for one: At 120cm across, the UK small double is 30cm wider than the UK single, so a solo sleeper can stretch out on that firm surface without a bigger footprint than needed.
- Fits rooms a double crowds: It is 15cm narrower than the UK double, which can be the difference between a bedroom door clearing the frame and one that scrapes past it.
- Firm support at this scale: The pocket spring core delivers the same extra firm, orthopaedic-style feel here as in larger sizes, which suits back sleepers who want a flat, supportive base.
- Same length as a single: Both the UK small double and the UK single are 190cm long, so upgrading from a single adds width without needing a longer room.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets are simple to find, and a standard double duvet drapes generously over it.
This size suits you if...
You're a solo sleeper who has outgrown a single and wants space to spread out on a properly firm surface, or you need a shareable bed in a box room, loft conversion or small guest room where a standard double would leave no walking space. It also suits a teenager moving up from a single without giving up the floor area they still use.
Consider another size if...
You and a partner would sleep on it every night, since 120cm is a squeeze for two on an extra firm surface. We'd recommend the UK double instead, which is 15cm wider; allow at least 2.6m x 2.8m for it.

Is a small double Legend Ortho big enough for a couple?
For occasional nights, yes. Two adults can share a UK small double for a guest room stay or the odd weekend, and the extra firm feel means neither sleeper rolls towards the middle. For nightly sharing, 120cm gives each person noticeably less space than a UK double, so we'd suggest sizing up if the room allows.
What room size do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m for the UK small double. That leaves enough room to walk around the bed and open drawers or a wardrobe. In a box room or studio, measure with the door swing in mind, as the 120cm width is often what decides whether the layout works.
How much bigger is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are exactly the same length at 190cm. That extra width is the whole point: a solo adult gets genuine spreading room on the Legend Ortho's firm surface without the bed taking up much more of the room.
Does the extra firm feel change in the smaller size?
No. The Legend Ortho uses the same cotton-rich cover, dense cushion layer and pocket spring core in every size, so the extra firm feel is consistent. What changes in the UK small double is simply the footprint, which makes it a practical way to get that firm support into a compact bedroom.
Where can I buy the Legend Ortho in a small double?
Availability shifts, so the most reliable answer is the live comparison table on this page, where prices are updated as retailers change them. Check that the listing specifies the UK small double, 120 x 190cm, as some retailers list several sizes of the Legend Ortho on a single product page.
