Layer Details
- Top Layer. A luxurious comfort quilting sits on top, which means a soft, cushioned surface the moment you lie down.
- Soft Foam. A 2cm layer of soft foam provides deep comfort through consistent weight distribution. In practice, that means your weight settles evenly rather than concentrating at the hips and shoulders.
- Springs. Traditional open coil springs provide even support across the whole mattress. Expect a slightly bouncier, more connected feel than pocket springs, so movement transfers a little more between partners.
- Non Slip Fabric. An anti-slip base adds stability, keeping the mattress in place on slatted or divan bases.

- Leaves room for everything else: At 90cm wide, the UK single frees up floor for a desk, wardrobe and toy storage, which matters when a child's bedroom has to do several jobs at once.
- A slimmer fit for raised frames: The 21cm depth is lower than many hybrids, which helps on bunks and mid sleepers, but always check your frame's own maximum mattress depth before ordering.
- Gentle on lighter bodies: The Soft/Medium surface with a 2cm soft foam layer suits children and teens, whose lighter weight can make firmer mattresses feel unforgiving at the shoulder and hip.
- Stays put on slats: The non-slip base keeps the mattress from creeping on a slatted cabin bed or guest frame, so you're not straightening it every morning.
- Easy to pair in a twin guest room: Two UK singles side by side let guests who aren't a couple sleep separately, and the open coils give each bed even, familiar support.
This size suits you if...
You're furnishing a child's or teenager's room where floor space is tight, you need a mattress for a bunk, cabin or mid sleeper frame, or you're setting up a spare room or loft conversion that has to fit a bed alongside a desk.
Consider another size if...
You're an adult who sprawls or shares the bed, even occasionally. We'd recommend the UK small double instead: it's 30cm wider at the same length, and we suggest at least 2.4m x 2.8m.

Will the SleepSoul Air UK single fit a bunk bed or mid sleeper?
It's 90 x 190cm, the standard UK single footprint most bunks and mid sleepers are built around. At 21cm deep it's a slimmer mattress than many, but raised frames usually set a maximum depth so the guard rail stays effective. Check your frame maker's guidance before buying.
Is the SleepSoul Air UK single a good mattress for a child's room?
For most children and teens, yes. The Soft/Medium feel cushions lighter bodies well, and the open coils keep support even across the surface. It's a slim, straightforward build, so a teenager who has grown heavy or prefers a firm bed may find it a little too yielding.
What size room do I need for a SleepSoul Air UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves space to walk around the bed and open drawers or a wardrobe. In a loft conversion, measure the flat floor area under the slope rather than the whole room.
Can I put two SleepSoul Air single mattresses in a guest room?
Yes, and it's a practical setup for guests who'd rather not share, such as siblings or friends. Each UK single has its own open coil unit, so one person turning over won't jostle the other the way it might on a shared mattress. Leave a walkway between the two beds.
Should I get the SleepSoul Air in a UK single or UK small double?
The UK single is 30cm narrower than the UK small double, and both are the same length. The UK single suits children and compact rooms. For an adult sleeping alone who likes room to stretch, the UK small double is more comfortable; we suggest at least 2.4m x 2.8m for it.
