Layer Details
- Silk. Soft in texture and light in weight, silk forms the top comfort layer. It gives the sleep surface a gentle, luxurious feel.
- Cashmere. A rare filling that is softer and finer than wool, typically found in quality mattresses. It adds a touch of plushness above the firmer layers below.
- Authentic Traceable British Wool. This wool is 100% traceable from farm to shop and comes from British Cheviot sheep, known for a strong yet soft fleece. It provides a natural bounce and helps regulate your temperature through the night.
- 1000 Pocket Springs. Each spring sits in its own fabric pocket, so they work completely independently of one another. That means better pressure-relieving support that responds to your body rather than the whole bed moving at once.

- Real stretching room for one: At 120cm wide you get 30cm more space than a UK single, which means you can shift position at night without an arm hanging off the edge.
- Fits where a double cannot: Being 15cm narrower than a UK double, it can be the difference between a bedside table on each side and a door that only half opens.
- Firm support in a compact size: The 1,000 pocket springs and firm tension suit back and front sleepers who want a solid, orthopaedic feel without giving the room over to the bed.
- Wool that manages heat in a smaller room: Compact bedrooms and lofts can run warm, and the traceable British wool helps regulate your temperature through the night.
- Handles occasional guests: Two people can share for the odd night comfortably enough, and the independent springs mean one sleeper's movement disturbs the other less.
This size suits you if...
You're a solo adult who has outgrown a UK single and wants room to spread out, but your bedroom, box room or loft conversion can't take a full double frame. Or you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, and you'd rather keep floor space for the rest of the room. Allow at least 2.4m x 2.8m of floor space.
Consider another size if...
You share the bed every night. At 120cm wide, a small double is a squeeze for two on a firm mattress long term, so we'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m for it.

Is a small double big enough for a couple on the Cashmere Ortho 1000?
For occasional nights, yes. The pocket springs move independently, so you feel less of your partner shifting about, and the firm tension keeps the surface stable near the edges. For nightly sharing, though, 120cm is tight, and the UK double, 15cm wider, is the more comfortable long-term choice.
What room size do I need for the Cashmere Ortho 1000 in a small double?
We suggest a room of at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers or a wardrobe. The mattress itself is 120 x 190cm, so measure your usable floor, allowing for sloped ceilings if it's going into a loft.
Is the small double the same length as a double?
Yes. The UK small double and the UK double are both 190cm long; only the width differs, with the UK small double 15cm narrower. If you're tall and want extra length, the UK king is 10cm longer than the UK small double, though it's also 30cm wider, so check your room first.
Where can I buy the Cashmere Ortho 1000 in a small double?
Compare the retailers listed on this page. The prices shown here are updated as retailers change them, so it's worth checking back if you're not buying straight away. Availability at 4ft can differ from the more common UK double, so the live table is the most reliable guide.
Will a firm mattress feel different in a smaller size?
The feel is identical: same firm tension, same 1,000 pocket springs, same silk, cashmere and wool layers. What changes is how you use the space. A solo sleeper on 120cm can spread out freely, whereas two people sharing will sit closer to the centre, where the support is at its most consistent.
