Layer Details
- Cover. A soft knit cover that feels cool to the touch. Breathable micro-dots move air outwards, which means the sleep surface stays fresher through the night.
- Emma AirGrid™ Tech layer. A flexible grid engineered to adapt to your body, giving instant pressure relief. It also boosts airflow, so it cushions you without holding heat the way solid foam can.
- MemoryAdapt layer. Memory foam that responds to your body for immediate cushioning. It contours to your curves and relieves pressure, giving that cosy, cradled feeling.
- SupportBase layer. This layer eases strain on sensitive pressure points and creates a smooth transition down to the core. The result is balanced firmness that supports you without letting you sink.
- Zoned pocket springs. Springs zoned to give responsive support where you need it, while reducing motion transfer so a partner's movement is less likely to disturb you. A strong foam frame around the edges keeps the perimeter stable.
- SupportBase layer. A second SupportBase layer grounds the spring core and keeps the structure stable. It gives the mattress a solid, lasting foundation.
- Bottom cover. A base cover that keeps the mattress in position on your bed frame, all night every night.

- Genuine space for one: At 120cm wide, a solo sleeper gets a full 30cm more width than a UK single, which means you can spread out or change position freely.
- Fits rooms a double cannot: Being 15cm narrower than a UK double, it slots into box rooms, studios and loft conversions where a 4ft 6in frame would block walking space.
- Cooling matters more when you sprawl: The AirGrid™ Tech grid moves air through the surface, so a solo sleeper using the whole width stays cooler than on solid memory foam.
- Usable edges on a narrow bed: The foam frame around the perimeter keeps the sides stable, which counts for more on a 120cm mattress where you sleep closer to the edge.
- Copes with occasional sharing: Zoned pocket springs limit motion transfer, so a couple staying for a weekend can share without every turn waking the other.
This size suits you if...
You sleep alone most nights and have outgrown a UK single but your room cannot take a full double, you're furnishing a guest room that hosts couples a few weekends a year, or you're downsizing and the bed has to fit the new bedroom rather than the old one. Allow at least 2.4m x 2.8m of floor space and the UK small double works well.
Consider another size if...
You share the bed every night, because 120cm is a squeeze for two adults long term. We'd recommend the UK double instead, or the UK king if your room and budget can stretch to it.

Is the Emma Performance 26 small double big enough for a couple?
For occasional nights, yes. The zoned pocket springs reduce motion transfer and the foam edge frame keeps the sides supportive, so two people can share comfortably for a weekend. For every night, 120cm is tight for two adults, and we'd point couples to the UK double or UK king of this mattress instead.
What room size do I need for the Emma Performance 26 in a small double?
We suggest allowing at least 2.4m x 2.8m. That gives you space to open the door, walk round the bed and fit a bedside table, which is exactly the situation where this size beats a UK double: 15cm less width often decides whether the room still functions.
What bedding fits the Emma Performance 26 small double?
You'll need small double (4ft) fitted sheets to match the 120 x 190cm surface. A standard double duvet works well on top and gives a little overhang on each side. Because 4ft is a standard UK size, sheets and frames are easy to find on the high street.
Is a small double worth it over a single for one person?
If the room allows, usually yes. The UK small double is 30cm wider than a UK single, which changes how the bed feels for an adult who moves around at night. On this mattress you also get the full hybrid build, springs, foam and grid, identical to the bigger sizes.
Where can I buy the Emma Performance 26 in a UK small double?
Availability shifts, so the most reliable answer is the live price table on this page, which updates as retailers change their listings. Smaller sizes like the UK small double are sometimes stocked less widely than the UK double or UK king, so it's worth checking back if you don't see the price you hoped for.
