Layer Details
- Cashmere. A luxuriously soft natural filling that breathes well and wicks moisture, which means less clamminess on warm nights. It sits at the sleep surface for a gentle first feel.
- Wool. Wool is a natural insulator with strong temperature-regulating properties. In practice it helps keep you warm in winter and cooler in summer, making it useful all year round.
- Silk. Silk adds a sumptuous, breathable layer of comfort. It's resilient too, so the surface should keep its feel rather than flattening quickly.
- Mini Pocket Springs. 2,000 small, individually cased springs sit slightly compressed to retain their springiness. They add a responsive comfort layer with soothing pressure relief for hips and shoulders.
- Pocket Springs. 1,000 traditional pocket springs, each encased in its own cloth pocket, react individually to your shape. That means adaptive support and less motion transfer to a partner.

- Real room for one: The UK small double is 30cm wider than the UK single, which means a solo sleeper can stretch out without giving up much floor space.
- Fits where a double won't: At 15cm narrower than the UK double, it can be the difference between a door that clears the bed and one that doesn't.
- Natural fillings in a compact size: Cashmere, wool and silk breathe and regulate temperature, useful in small rooms where warm air has nowhere to go.
- Handles the occasional shared night: The 3,000-spring system reacts to each sleeper individually, so a guest room couple won't feel every turn the other makes.
- Standard 4ft sizing: Small double is a recognised UK size, so frames and fitted sheets are straightforward to find.
This size suits you if...
You sleep alone and have outgrown a single but your room can't take a full double, you're furnishing a box room, studio or loft conversion where every centimetre of width matters, or you need a guest room bed that copes with the occasional couple without dominating the space. The medium firm feel suits back and combination sleepers best.
Consider another size if...
You share the bed every night, in which case 120cm across two adults will feel tight with this fairly firm surface. We'd recommend the UK double instead; allow at least 2.6m x 2.8m of floor space for it.

Is a small double big enough for the Aspire Cashmere and Silk 3000 to suit a couple?
For occasional nights, yes. The pocket springs respond to each person separately, so a visiting couple should sleep reasonably undisturbed. As an every-night bed for two, 120cm of width is snug, and the medium firm feel leaves little give to sink into. Full-time couples would be better served by the UK double.
What size room do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves enough clearance to walk round the bed and open the door, which is usually the deciding factor in box rooms and loft conversions. If your room comfortably exceeds that, the UK double needs at least 2.6m x 2.8m and gives you 15cm more width.
How much bigger is the UK small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. In practice that extra width is the difference between sleeping in one fixed position and being able to spread out, which is why it suits teenagers and adults who have outgrown a single.
Is the small double Aspire Cashmere and Silk 3000 easy to move upstairs?
Plan for two people. Owner reviews of this mattress consistently mention its weight, which comes from substantial natural fillings rather than padding. The small double is the model's more manageable end compared with the UK king or UK super king, but tight staircases into lofts and box rooms, exactly where this size ends up, still need care.
What bedding fits the Aspire 3000 in a small double?
You need small double (4ft) fitted sheets to match the 120 x 190cm surface. It's a standard UK size, so sheets are easy to find, and a standard double duvet works well on top, with the overhang sitting nicely on the narrower frame.
