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.
Layer details from emma-sleep.co.uk product page, September 2026.
- Space that works with the springs: The zoned pocket springs reduce motion transfer, and at this width you also get physical distance from a fidgeting partner, which does more than any comfort layer can.
- Room for the whole household: With 90cm each for two people sharing, a child climbing in at 3am leaves everyone with a workable share of the bed.
- Airflow across a bigger surface: The AirGrid™ Tech layer boosts airflow, useful when three bodies or a dog raise the temperature under one duvet.
- A stable perimeter you'll actually use: The foam frame around the edge keeps the sides supportive, which matters more at this size because someone usually ends up sleeping near them.
- Fills a large master properly: In a period property or generous new build master where a UK king looks undersized, the 180cm width sits in proportion with the room.
This size suits you if...
You share the bed every night and want the maximum distance from a partner's tossing and turning, your children or pets treat your bed as their own and you'd rather plan for it than fight it, or your bedroom is large enough that a UK king would look lost. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling comfortable.
Consider another size if...
Your room falls short of our suggested 3m x 2.9m minimum, or you sleep alone and the extra width would go unused. We'd recommend the UK king instead: still a generous bed for two, and easier to live around.

Is the Emma Performance 26 in a UK super king good for restless partners?
Yes, arguably more than any other size. The zoned pocket springs are designed to reduce motion transfer, but at 180cm wide you also get 90cm each for two people sharing, so most movement simply happens too far away to wake you. Distance and springs together beat springs alone.
Will the Emma Performance 26 super king fit in my bedroom?
The mattress measures 180 x 200cm, which is 6ft x 6ft 6in. We suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling right, so you can open drawers and walk around the bed. In a loft conversion, check the slope leaves a wall long enough to take the 180cm width.
Is the UK super king big enough to share with children or pets?
This is the size for it. With 90cm each for two adults, a child arriving in the night or a large dog claiming the foot of the bed still leaves everyone a reasonable share. The breathable AirGrid™ layer helps too, since extra bodies under one duvet tend to push the temperature up.
How much bigger is the super king than the king in this mattress?
The UK super king is 30cm wider than the UK king, at 180cm against 150cm, and both are 200cm long. That extra width is the difference between sharing comfortably and negotiating territory, particularly if one of you spreads out. If your room can take it, the upgrade is mostly upside.
Is a super king Emma Performance 26 hard to get upstairs?
It is the size where access checks start to bite. Measure your door swing, stairway width and any landing turns before ordering, since a 180 x 200cm mattress is awkward on a tight staircase even when rolled. Emma doesn't publish handling guidance for this size, so check with the retailer if your access is tricky.
