- Fits the smallest rooms: At 90cm wide, it slots into box rooms, loft conversions with a narrow footprint and children's bedrooms where the bed shares space with a desk and wardrobe.
- Springs that grow with a child: The mini pocket spring layer offers more responsive support than budget all-foam children's mattresses, which matters as a child gets heavier through their teens.
- Cooling where kids need it: The moisture-wicking UltraDry cover and breathable Airgocell foam help warm sleepers, and children often run hot at night.
- Guest room friendly: A single keeps floor space free in a spare room that spends most of its life as an office, with a proper hybrid feel for the few nights guests stay.
- Pairs well as two beds: Two UK singles side by side or on opposite walls suit siblings sharing a room, or a guest room deliberately set up for two visitors.
This size suits you if...
You're buying for one sleeper, most often a child, teenager or single adult, and want a proper hybrid feel rather than a basic foam slab. It also fits if your spare room doubles as an office and only hosts guests occasionally, or you're kitting out a student room or first flat where the frame is provided but the mattress isn't.
Consider another size if...
You're an adult who spreads out in your sleep, or you sometimes share the bed. At 90cm wide the UK single leaves little spare room, so we'd recommend the UK small double instead for a solo sleeper wanting more space.

Is the Emma Hybrid UK single big enough for an adult?
Yes, for most solo adults. At 90 x 190cm, or 3ft x 6ft 3in, it's the standard UK one-person size, and the memory foam layer cushions pressure points even on a narrower surface. Restless sleepers or anyone who likes to sprawl may feel confined, in which case the UK small double is the sensible step up.
Will the Emma Hybrid single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. The sticking point is depth: raised frames need the mattress to sit below the guard rail for safety, and Emma doesn't publish a depth figure we can quote here, so check the retailer's listing against your frame's maximum before buying.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or wardrobe doors. In a child's room the single's 90cm width is the real advantage, leaving space for toy storage and a desk that a wider bed would swallow.
Should I buy the Emma Hybrid in a UK single or a UK small double?
The UK single is 30cm narrower than the UK small double, which is a noticeable difference for an adult sleeping alone. Choose the UK single for a child, a compact room or a bunk frame. If the room can take the extra width and the sleeper is an adult, the UK small double is more comfortable long term.
Is the Emma Hybrid single a good choice for a child's bed?
It's a reasonable step up from entry-level foam. The mini pocket springs support a growing body, the memory foam eases pressure, and the UltraDry cover helps children who overheat at night. One caveat: Emma doesn't publish a firmness rating for this mattress, so check the retailer's description if your child needs a particular feel.
