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.

- Fits where other beds won't: At 3ft wide, this size slots into box rooms, loft conversions with a narrow footprint under the slope, and spare rooms that double as an office.
- Natural fillings for a growing sleeper: Cashmere, wool and silk breathe and regulate temperature, which means a teenager who sleeps warm gets a fresher surface than a synthetic-topped single offers.
- Medium firm support at any age: The two-tier pocket spring system adapts to lighter bodies as well as adult ones, so it works for a child now and a student flat later.
- Guest-ready without fuss: Single sheets and duvets are the cheapest and most widely stocked of any size, handy for a spare bed that only sees occasional use.
- Works in a shared children's room: Two UK singles plus a walkway fit in most sibling bedrooms, and the individually cased springs mean one restless sleeper disturbs the other less through a shared wall of furniture.
This size suits you if...
You're buying for a child or teenager's room where the bed competes with a desk, wardrobe and toy storage, you need a proper mattress for a guest bed or a spare room that moonlights as an office, or you're a solo adult in a compact bedroom, student room or first flat where the frame came with the property and the mattress didn't.
Consider another size if...
You're an adult who spreads out at night, or you're furnishing a room a couple might use. We'd recommend the UK small double instead: it's 30cm wider than the UK single, the same length, and needs at least 2.4m x 2.8m of floor space.

What are the dimensions of the Aspire Cashmere and Silk 3000 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any single bed frame, divan or slatted base without adjustment, and standard single sheets and a 135 x 200cm single duvet fit it.
Will the UK single Aspire 3000 fit a bunk or mid sleeper?
The footprint fits: bunks, cabin beds and mid sleepers are built around the 90 x 190cm UK single. The catch is depth. At 28cm this is a tall mattress, and raised frames need a good stretch of guard rail above the sleep surface. Measure the rail height before ordering for a top bunk.
Is the UK single Aspire Cashmere and Silk 3000 suitable for a child?
Yes, with one caveat. The medium firm feel and adaptive pocket springs suit growing backs, and the natural fillings are hypoallergenic and breathable. Lighter children who sleep mainly on their side may find it a touch firm on the shoulder, so it's better matched to older children and teens than to toddlers moving up from a cot bed.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which is our own guidance rather than the manufacturer's. That leaves room to walk around the bed and open drawers or a wardrobe. In a child's room it also keeps space free for a desk and storage, which is usually the whole point of choosing this size.
Can one person rotate the single size of this mattress?
Across owner reviews the Aspire 3000 is described as very heavy, a result of its substantial natural fillings. The UK single is the smallest and most manageable size of the range, but we'd still suggest a second pair of hands, especially if the bed sits against a wall or in a tight corner.
