That trial gives you plenty of time to settle in before committing, which matters with a mattress at a premium starting price.

Why should you choose this mattress?
The main draw is the layered construction. The AirGrid™ layer is a flexible grid designed to adapt to your body for pressure relief, while the MemoryAdapt layer beneath gives that initial cushioned hug when you lie down. Under that, zoned pocket springs add bounce and stability while reducing motion transfer, which means you're less likely to feel a partner shifting in the night. The 28 cm depth is pitched by Emma as giving more consistent body-moulding and fit. Add free delivery in 2 to 7 working days, a 200-night trial and a 10-year guarantee, and it's a fairly low-risk purchase, albeit not a cheap one.
Key features & layer details
Cover
A knit cover with breathable micro-dots that move air outwards, designed to feel cool and ultra soft. It's the first thing your skin meets, so the airflow focus should help if you tend to run warm.
Emma AirGrid™ Tech
Emma's most advanced AirGrid™ layer, a flexible grid engineered to adapt to your body. In practice, this means pressure relief that adjusts to your shape rather than pushing back uniformly.
MemoryAdapt layer
This gives the first comforting hug, responding to your body with immediate cushioning. It's where the pressure relief you feel at hips and shoulders comes from.
SupportBase
A transition layer that keeps you supported in every zone, easing strain on sensitive pressure points. It also creates a smooth handover to the core layers, so you don't feel a sudden change in feel as you sink in.
Zoned pocket springs
These add bounce, extra support and stability, with zoning to give responsive support where you need it. The pocketed design also reduces motion transfer, useful if you share the bed.
SupportBase
A second SupportBase layer that grounds the zoned spring core and keeps the mattress structure stable. Think of it as the foundation everything else works from.
Bottom cover
A simple base cover that keeps the mattress in place on your bed frame.

Best suited for?
Couples
Zoned pocket springs reduce motion transfer, which means you are less likely to feel a partner shifting during the night.
Warm sleepers
The knit cover has breathable micro-dots that move air outwards, designed to feel cool and ultra soft against your skin if you run warm.
Side sleepers
A MemoryAdapt layer gives an initial cushioned hug, and it is where the pressure relief at hips and shoulders comes from.
Combination sleepers
Bouncy zoned pocket springs and a flexible AirGrid layer adapt to your shape, so changing position through the night feels responsive rather than sticky.
Back sleepers
Zoned pocket springs give responsive support where you need it, while the SupportBase layers keep the feel consistent as you sink in.
At 28 cm deep, this is a tall mattress, so some standard fitted sheets may struggle and adjustable bases may not suit it. If you prefer a very simple all-foam feel, the springy, bouncier character of the hybrid core may not be for you. Budget shoppers may also find the larger sizes a stretch.
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.
