Layer Details
Comfort fillings
Two layers combining polyester and cotton sit at the sleep surface, which means a soft, cushioned first impression when you lie down. The cotton adds a touch of natural breathability to the synthetic fill.
Soft white fibres
Beneath the comfort layers, two layers of soft white fibres help air circulate through the mattress. This works to move heat and moisture away from you, so the bed feels fresher for longer.
Pocket springs
1000 pocket springs form the core of the mattress, each moving independently to follow the shape of your body. Their curved design is intended to react quickly and spring back, so the mattress shouldn't feel dead or unresponsive when you change position.

Key benefits
- Leaves floor space free: At 90 x 190cm, the UK single fits alongside a desk and wardrobe, which means a child's bedroom still has room for play and storage.
- Support that follows one body: The 1000 pocket springs move independently, so a restless child or teenager gets support that adjusts as they turn rather than a surface that shifts as one block.
- A middle ground for guests: The medium firm feel is a reasonable compromise for a spare room, where you rarely know whether the next visitor prefers soft or firm.
- Fresher in a small, warm room: Layers of soft white fibre help air move through the mattress, useful in a compact bedroom or loft conversion that holds heat on summer nights.
- Fits a standard frame: Measuring 3ft x 6ft 3in, the UK single matches the standard single frames found in student rooms and first flats, where the bed comes but the mattress doesn't.
This size suits you if...
You're buying for a child or teenager whose room also has to hold a desk and wardrobe, you sleep alone in a compact bedroom, or you're kitting out a spare room or student let where a standard single frame is already in place.
Consider another size if...
You're an adult who likes to sprawl, or the bed will regularly be shared. We'd recommend the UK small double instead, which is 30cm wider and needs at least 2.4m x 2.8m.

FAQ's
Will the Wentworth Mercer Natural Pocket 1000 UK single fit a bunk bed or mid sleeper?
The UK single matches standard single bunk and mid sleeper frames in width and length, but the mattress is 29cm deep. Raised frames usually set a maximum mattress depth so the guard rail stays high enough, so check the frame manufacturer's guidance before buying.
What size room do I need for a UK single Wentworth Mercer Natural Pocket 1000?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves space to walk around the bed and open drawers, which matters in a child's room already holding a wardrobe and desk. If the room is tighter still, measure your door swing before committing.
Is a UK single mattress long enough for a tall teenager?
The UK single is 190cm long, or 6ft 3in, which suits most teenagers comfortably. If your teenager is already close to that height, the UK king is 10cm longer, although it is also far wider and needs a much larger room.
UK single or UK small double for a spare room office?
If the room also holds a desk, the UK single keeps a working area clear and needs at least 2.1m x 2.8m. The UK small double is 30cm wider and the same length, which suits guests who stay a few nights, but we suggest at least 2.4m x 2.8m.
Does a single Wentworth Mercer Natural Pocket 1000 work in a loft conversion?
A UK single's narrow 90cm width is often the only bed that fits under a sloping ceiling. Measure the headroom where the mattress will sit, remembering it adds 29cm of depth on top of the frame, so a sleeper can sit up without hitting the slope.
