Layer Details
- Knitted cover. A soft knitted cover with breathability, which means heat can escape rather than building up at the surface. It's a simple touch but a welcome one on a memory foam mattress.
- 6cm memory foam. This layer adapts to the contours of your body for soothing pressure relief. In practice, that means a gentle cradling feel around your hips and shoulders as you settle in.
- 14cm Reflex foam core. A supportive core that creates the medium to firm feel. This is what keeps your spine aligned and stops you sinking too far into the mattress.

- Fits where other sizes won't: At 3ft x 6ft 3in, it slots into box rooms, loft conversions and shared children's bedrooms where a wider mattress would swallow the floor.
- Bunk and mid-sleeper friendly: The UK single is the size raised frames are built around, and at 20cm deep it sits sensibly below most guard rails.
- Support that suits younger sleepers: The firmer Reflex foam core keeps a light body from sinking too far, which matters for children and teens still growing.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, useful when a child's bedding needs replacing often.
- Rolled delivery for awkward rooms: It arrives rolled, so getting it up a bunk ladder-side staircase or into a loft room is far easier than hauling a flat mattress.
This size suits you if...
You're buying for a child or teenager moving up from a cot or first bed, you need a mattress for a bunk, cabin or mid-sleeper frame, or you're kitting out a spare room or student flat where the frame is a single and the budget is tight. It also suits a solo adult sleeper in a compact room who wants floor space left over.
Consider another size if...
You're an adult who sleeps alone but likes room to spread out, or you toss and turn at night. We'd recommend the UK small double instead: it's 30cm wider than the UK single, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Will the Bodyshape Classic UK single fit a bunk bed or mid sleeper?
Yes, in most cases. The UK single is the size bunk, cabin and mid-sleeper frames are designed around, and this mattress is 20cm deep, which usually leaves the guard rail doing its job on a top bunk. Check your frame's maximum mattress depth before buying, as some bunks specify a lower limit.
What room size do I need for the Bodyshape Classic in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open a wardrobe or drawers. In a child's room competing with toy storage and a desk, or a spare room that doubles as an office, the UK single's 90cm width is what keeps the room usable.
Is the Bodyshape Classic single a good first mattress for a child?
It's a sensible fit. The medium to firm feel comes from a supportive Reflex foam core, so a lighter body won't sink too deeply, and the mattress is hypoallergenic. Do note memory foam holds some warmth, so a hot-sleeping child may want lighter bedding. The breathable knitted cover helps heat escape at the surface.
Should I buy the UK single or the UK small double?
The UK single is 30cm narrower than the UK small double, and the two are the same length. For a child, a bunk frame or a tight room, the UK single is the right call. For an adult sleeping alone who wants more elbow room, the UK small double suits better; allow at least 2.4m x 2.8m for it.
Is the Bodyshape Classic UK single long enough for a teenager?
At 190cm long it accommodates most teens and adults comfortably. If you're buying for someone notably tall, the UK king is 10cm longer than the UK single as well as 60cm wider, though it needs a much bigger room: we suggest at least 2.7m x 2.9m. For most teenage bedrooms the UK single's length is fine.
