Assessed from Emma's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The strongest case for this mattress is temperature and pressure relief working together. The AirGrid™ Tech layer is a flexible grid designed to boost airflow while adapting to your body, which means hot sleepers get pressure relief without the heat build-up traditional memory foam can trap. Beneath it, a MemoryAdapt layer adds that cradled feeling, and zoned pocket springs reduce motion transfer, so a restless partner is less likely to wake you. A foam frame around the edge adds stability when you sit or sleep near the side. Add a 200-night trial and 10-year guarantee direct from Emma, and it is a fairly low-risk purchase for a hybrid at this price.
Key Features & what's inside
- 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.

Who's it NOT for?
If you like a properly firm, sleep-on-top surface, the contouring memory foam layer here may feel a little too cradling. Equally, if you dislike any sense of hug at all, an all-spring or firmer hybrid may suit you better. Budget shoppers should note the from-price of £549 buys the smallest size only.
Emma Performance 26 Mattress
How deep is the Emma Performance 26 mattress?
It is 26cm deep, which the name refers to. That depth comes from seven layers, including the AirGrid™ Tech layer, memory foam and a zoned pocket spring core. Worth checking your fitted sheets are deep enough before it arrives.
Does the Emma Performance 26 come with a trial?
Yes. Bought from Emma's own site, it comes with a 200-night trial, which is longer than most brands offer, plus a 10-year guarantee. That gives you a full stretch of seasons to decide whether it suits you.
Is the Emma Performance 26 good for hot sleepers?
It is designed with heat in mind. The cover uses breathable micro-dots to move air outwards, and the AirGrid™ Tech layer is a flexible grid that boosts airflow while relieving pressure. If you usually find memory foam mattresses too warm, this construction should run noticeably cooler.
How firm is the Emma Performance 26?
Emma describes it as balanced comfort and support in every layer, so it sits in the middle ground rather than at either extreme. The memory foam gives a cradled feel, while the SupportBase layers and zoned springs stop you sinking too far.
How much does the Emma Performance 26 cost?
Prices range from £549 to £1,099 depending on size. Seven sizes are available, from UK Single up to UK Super King, plus EU Double and EU King. Delivery from Emma is free, arriving in 2 to 7 working days.
