Layer Details
Wool
Wool comfort fillings that stay cosy through the night, which means natural insulation in winter and temperature regulation in summer. It's the layer closest to you, so you feel its softness first.
Cotton
Natural cotton fibres that wick away moisture, which means a fresher, drier sleeping surface. Helpful if you run warm at night.
Hemp
An eco-friendly fibre that's naturally breathable and durable, adapting to different temperature conditions. It also acts as a natural insulator, adding to the mattress's temperature control.
Soft White Fibres
Soft synthetic fillings that add a cosy feel while staying resilient. This layer holds its shape over time, so the comfort shouldn't flatten quickly.
Eco-polyester
A supportive layer made from 100% recycled materials, and it can be recycled again at the end of its life. A quiet win if sustainability matters to you.
Pocket Springs
3750 Cortec Quad Core pocket springs, each encased in its own cloth pocket, which means each spring responds independently to your body. The design prioritises breathability and resilience.

- Fits compact rooms: At 90cm wide it leaves floor space free for a desk, wardrobe and toy storage in a child's room, or two beds with a walkway between them.
- 3750 springs in a single footprint: The full Cortec Quad Core spring system in a one-person size means support stays tailored across the whole 90cm width, edge to edge.
- Natural fillings for growing sleepers: Yorkshire wool and breathable hemp regulate temperature without foam, useful for children and teens who often run warm at night.
- Easier to turn than larger sizes: This mattress needs regular turning, and the UK single is the lightest size to handle, helped by the built-in turning handles.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are among the most widely stocked and affordable of any size.
- Guest room ready: In a spare room that doubles as an office, or a guest room taking two beds, the 90 x 190cm footprint keeps the room usable by day.
This size suits you if...
You're buying for a child or teenager and want a mattress with natural fillings that will handle years of growing, you sleep alone in a compact room or loft conversion where a wider bed won't fit, or you're furnishing a spare room and want a quality single rather than squeezing in a double.
Consider another size if...
You're an adult who finds 90cm of width restrictive, or you tend to sprawl. The UK small double would suit you better: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

What size is the Levisham 3750 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits standard single bed frames, single fitted sheets and a 135 x 200cm single duvet. We suggest allowing at least 2.1m x 2.8m of floor space around it.
Will the Levisham 3750 UK single work on a bunk or mid sleeper frame?
The footprint matches standard UK single bunk frames. At 24cm deep it's on the thicker side for a raised bed, so check your frame's maximum mattress depth and guard rail height first. Bear in mind it needs regular turning, which is more awkward on a top bunk than a standard frame.
Is a UK single Levisham 3750 big enough for an adult?
For most solo adults, yes: 90cm of width is workable if you sleep fairly still, and the medium firm feel gives solid support. If you move around a lot in the night, the UK small double is 30cm wider and the same length, and needs a room of at least 2.4m x 2.8m.
Is the UK single easy to rotate and turn?
Yes, and this matters here because the natural wool and hemp fillings benefit from regular turning to last well. The UK single is the smallest and lightest size in the range, and the turning handles make it a manageable job for one person, unlike the wider sizes.
Is the Levisham 3750 UK single a good choice for a child's room?
It's a strong fit. The 90 x 190cm footprint leaves room for a desk and storage, the breathable wool and hemp suit children who overheat at night, and the pocket spring construction should outlast cheaper foam singles. The medium firm feel supports growing spines, though very light children will find it firmer than an adult would.
