Emma Performance 28 EU King Mattress

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.
