Layer Details
- Microquilted Cover. A micro-quilted cover with fabric stitched into the filling beneath, which gives the surface a plush, quilted feel. It makes the top of the mattress feel smooth and soft from the first night.
- Soft White Fibres. Soft synthetic fillings that add a cosy layer of comfort just below the cover. They are durable and resilient, so they should hold their shape over time rather than flattening quickly.
- Memory Foam. Memory foam cradles to your shape, which means pressure points like hips and shoulders get a cushioned, contoured feel. It is what gives the mattress its sumptuous, sink-in comfort.
- Pocket Springs. 1000 pocket springs made from sturdy steel, curved to provide bounce. Each spring sits in its own fabric casing and moves independently, so your partner's movements are less likely to disturb you.

- Fits a busy child's bedroom: At 3ft wide it leaves room for a wardrobe, a desk and toy storage in the same space, which most sizes above it would not.
- Medium firm suits growing sleepers: The balance of spring support and memory foam cushioning works for children and teens, whose sleeping positions change often.
- Springs plus foam at a light weight class: You get pocket spring push-back with a cushioned surface, in a size that is far easier to rotate and move than the larger options.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are among the cheapest and most widely stocked bedding in the UK.
- Sensible for spare rooms and student flats: If a landlord or halls provide a single frame, this drops straight in, and it is a practical pick for a study that doubles as guest space.
This size suits you if...
You're buying for one sleeper: a child moving up from a cot bed, a teenager, or an adult who sleeps alone in a compact room. It also makes sense if you're furnishing a spare room or a student flat where a single frame is already in place, or if two beds need to share one children's room with a walkway between them.
Consider another size if...
You're an adult who tosses and turns and finds 90cm of width restrictive, or you occasionally share the bed. We'd recommend the UK small double instead, which is 30cm wider and the same length; allow at least 2.4m x 2.8m for it.

What size is the Bodyshape Boost 1000 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in, the standard UK one-person size. Standard single fitted sheets and a single duvet fit it without any adjustment, so you can use bedding you may already own.
Will the UK single Bodyshape Boost 1000 fit a bunk bed?
The 90 x 190cm footprint matches standard UK bunk, cabin and mid-sleeper frames. The one thing to check is depth: at 25cm this is deeper than many mattresses sold for raised frames, and a top bunk's safety rail needs to sit well above the mattress surface. Check your frame's maximum mattress depth before buying.
Is the Bodyshape Boost 1000 UK single a good choice for a child's room?
Yes, with a caveat. The medium firm feel gives growing sleepers proper support from the pocket springs with a soft, quilted surface on top. The caveat is warmth: memory foam can hold heat, so a child who already sleeps hot may need lighter bedding. Allow at least 2.1m x 2.8m of floor space.
How much floor space does a UK single mattress need?
We suggest at least 2.1m x 2.8m, which leaves enough room to walk alongside the bed and open drawers or a wardrobe. That makes this size a realistic fit under the slope of a loft conversion or in a box room where nothing wider would work.
Can I put two UK singles in one room for siblings or guests?
Often, yes, and two singles are more flexible than one bigger bed in a guest room. Our 2.1m x 2.8m suggestion covers one single with walking space, so a shared room needs noticeably more than that to fit a second bed and a walkway between them. Measure with both footprints marked out before ordering.
