Layer Details
Dense cushion layer
A dense layer of cushioning that sits on top of the spring unit. It adds some comfort to an already firm mattress, so the surface feels a little less harsh.
2000 pocket spring unit
A pocket spring unit with 2000 springs (the count is given for the king size), each moving individually. That means support follows your body's shape rather than moving as a single sheet.

Key benefits
- Room to sprawl on your own: At 30cm wider than a UK single, you can lie on your back or front with your arms out, which suits the flat posture this extra-firm mattress is built around.
- Fits rooms a UK double would crowd: We suggest allowing at least 2.4m x 2.8m, so it can work in a box room or loft conversion where a UK double would leave you squeezing past the frame.
- A little easier to turn: The mattress is double-sided, and its 120cm width is slightly more manageable to rotate and flip than the larger sizes.
- No specialist bedding needed: Small double fitted sheets and 4ft bed frames are widely sold in the UK, so you shouldn't need to hunt for anything unusual to dress or support it.
- Fine for the odd weekend guest: Two people can share for a short visit, although the narrower width suits occasional stays far better than nightly sharing.
This size suits you if...
You sleep alone, like a very firm surface and want more room than a UK single gives, 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 for two sharing; allow at least 2.6m x 2.8m for the UK double.

FAQ's
Is a UK small double Legend Ortho Plus big enough for two people?
For a weekend or the occasional visit, yes, and many people use a UK small double as a guest bed on that basis. For nightly sharing it's tight. The UK double gives 67.5cm each for two sharing, and the UK king gives 75cm each, so either is the better choice for couples.
What size room do I need for a UK small double Legend Ortho Plus?
We suggest at least 2.4m x 2.8m. That's our own guidance rather than the brand's, and it leaves room to walk around the bed and open a door. If your room reaches 2.6m x 2.8m, the UK double becomes an option too.
Will the Legend Ortho Plus small double fit in a loft conversion?
Often, yes. Loft rooms tend to lose usable floor where the roof slopes, and a UK small double is 15cm narrower than a UK double, which can be the difference between standing room beside the bed and none. Measure the full-height floor area, not the whole room, before you buy.
What sheets fit a UK small double Legend Ortho Plus?
Use small double (4ft) fitted sheets rather than double ones, which will sit loose and wrinkle on a 120cm mattress. A standard double duvet gives good coverage. The mattress is 30cm deep, so check that the fitted sheet's pocket depth is generous enough to tuck under.
Is a small double Legend Ortho Plus a good upgrade from a single for a teenager?
It gives 30cm more width than a UK single at the same length, so it suits a growing teenager in a room that can't spare much floor. Bear in mind it's extra firm, which lighter sleepers can find hard. If they're very tall, the UK king is 10cm longer, though much wider.
