The Emma Performance 30 combines an Emma AirGrid™ Tech layer, a memory foam MemoryAdapt layer and zoned pocket springs, which means you get pressure relief at the surface with responsive support underneath. Emma describes it as offering maximum height for personalised cushioning and tailored support. It comes in seven sizes, including EU Double and EU King. Emma's own site lists a 200-night trial and a 10-year guarantee, which gives you plenty of time to be sure. It is a premium spend, but the layered build goes some way to justifying it.

Why should you choose this mattress?
If you want deep, hug-like cushioning without giving up support, this is the model in Emma's range built for exactly that. The MemoryAdapt and SupportBase layers are thicker here than in other Performance models, at 4.5 cm and 6.5 cm respectively, which means a more enveloping feel when you first lie down. The AirGrid™ layer is a flexible grid engineered to adapt to your body, and the zoned pocket springs add bounce while reducing motion transfer, useful if you share a bed with a restless partner. Add the 200-night trial and 10-year guarantee from Emma, plus free delivery in one to three weeks, and the risk of trying it is fairly low. Yes, it has a premium starting price, but you are paying for the range-topping build.
Key features & layer details
Cover
A knit cover designed to feel cool and ultra soft, with breathable micro-dots that move air outwards. In practice, that should help the surface stay fresher through the night.
Emma AirGrid™ Tech
Emma's most advanced AirGrid™ layer, a flexible grid engineered to adapt to your body. It is there for pressure relief, flexing where you press into it rather than pushing back evenly.
MemoryAdapt layer
This is the layer that gives the first comforting hug, responding to your body with immediate cushioning to relieve pressure. In the Performance 30 it is 4.5 cm thick, deeper than in other models in the range.
SupportBase
A 6.5 cm foam layer that keeps you supported in every zone, easing strain on sensitive pressure points. It also creates a smooth transition down to the core layers, so you shouldn't feel a sudden change in firmness.
Zoned pocket springs
Zoned pocket springs add bounce, extra support and stability, which means the mattress responds when you move rather than leaving you feeling stuck. They also reduce motion transfer, a quiet benefit for couples.
SupportBase
A second foam layer that grounds the zoned spring core and keeps the mattress structure stable. Think of it as the foundation the rest of the build sits on.
Bottom cover
A simple base cover that keeps the mattress in place on your bed frame.

Best suited for?
Side sleepers
The 4.5 cm MemoryAdapt layer gives an enveloping, hug-like feel, which means shoulders and hips can sink in comfortably while the springs below keep you supported.
Couples
Zoned pocket springs reduce motion transfer, which means a restless partner is less likely to disturb you when they move or turn over.
Warm sleepers
The knit cover has breathable micro-dots that move air outwards, which should help the surface stay fresher through the night.
Combination sleepers
Pocket springs add bounce, so the mattress responds when you move rather than leaving you feeling stuck as you change position.
European bed frames
Seven sizes are offered, including EU Double and EU King, so you can match the mattress to a continental frame.
If you prefer a firm, on-top-of-the-mattress feel, the deep cushioning here may feel too enveloping. It is also a premium buy, so budget shoppers will find better value elsewhere in Emma's own range, where the cushioning layers are slightly thinner.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How long is the trial on the Emma Performance 30 mattress?
Emma's own site lists a 200-night trial on the Performance 30, which is longer than most brands offer. That gives you several months at home to decide whether the feel suits you before committing.
Does the Emma Performance 30 have springs or is it all foam?
It's a hybrid. Alongside foam layers, including a memory foam MemoryAdapt layer and grid foam AirGrid™ Tech, it has a core of zoned pocket springs that add bounce and support while reducing motion transfer. Emma doesn't publish a spring count for this model.
What sizes does the Emma Performance 30 come in?
Seven sizes: UK Single, UK Small Double, UK Double, UK King, UK Super King, plus EU Double and EU King. The EU options are handy if you have a continental bed frame.
How firm is the Emma Performance 30 mattress?
Emma doesn't give a firmness rating on a numbered scale. The brand describes the Performance 30 as offering maximum height for personalised cushioning and tailored support, and it is positioned as the maximum comfort option in the range, with the deepest cushioning layers.
How long does Emma Performance 30 delivery take?
Emma lists free delivery taking one to three weeks. The mattress also comes with a 10-year guarantee, so you're covered well beyond the trial period.
