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.

Key benefits
- Fits compact rooms: At 90cm wide it leaves floor space free for a desk, wardrobe or toy storage, and we suggest allowing at least 2.1m x 2.8m of room.
- Natural fillings for one sleeper: The British wool layer regulates temperature naturally, which helps a teenager or guest who runs warm at night.
- Firm support for growing sleepers: The firm tension and 1,000 pocket springs give back and front sleepers steady, even support rather than a sinking feel.
- Hypoallergenic for a child's room: The mattress is rated hypoallergenic, reassuring if a child's allergies flare up at night.
- Check raised frames first: At 28cm deep it has a substantial, traditional build, so measure against guard rails before putting it on a bunk or mid sleeper.
This size suits you if...
You're buying for a child or teenager who needs firm, supportive sleep in a room where the bed shares space with a desk and storage, you're furnishing a guest room or a spare room that doubles as an office, or you're a single adult who sleeps on your back or front and wants a solid feel with natural fillings.
Consider another size if...
You share the bed, or you're a solo sleeper who spreads out and finds 90cm restrictive. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

FAQ's
Is the UK single Cashmere Ortho 1000 suitable for a bunk bed?
Measure before you buy. At 28cm deep this is a substantial mattress, and bunk and mid-sleeper frames usually need the mattress to sit below the guard rail for safety. If your frame specifies a maximum depth under 28cm, a slimmer mattress would be the safer choice for a raised bed.
What room size do I need for the Cashmere Ortho 1000 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. The UK single measures 90 x 190cm, so it works well in a child's bedroom where the bed competes with a wardrobe and desk, or in a loft room where the sloping ceiling limits where a bed can go.
Is the UK single Cashmere Ortho 1000 good for a child or teenager?
It suits most children and teens who sleep on their back or front, and the hypoallergenic rating plus natural wool fillings are a bonus for a child's room. It is firm, though, so a lightweight child who sleeps on their side may find it a little hard at the shoulders and hips.
How much narrower is a single than a double in this mattress?
The UK single is 45cm narrower than the UK double, and the two are the same length. For one sleeper who likes room to spread out, the UK double gives noticeably more space; for a compact bedroom or guest room, the UK single is the easier fit.
