Layer Details

Knitted cover
A soft knitted finish that adds a touch of cosiness, which means the surface feels inviting rather than clinical. Knitted covers are breathable and help air move through the sleep surface.

Memory Foam
A 5cm layer of memory foam that moulds to your shape, which means pressure is lifted from your hips and shoulders as you settle in. Expect a gentle sink-in feel rather than sleeping on top of the mattress.

Soft White Fibres
A dense layer of soft synthetic fillings that adds cosy comfort while reinforcing the medium to firm feel. It also works as an insulator pad, protecting you from feeling the spring unit beneath.

Pocket Springs
A core of 1400 pocket springs, each in its own fabric pocket, adapts to your movement through the night. Because the springs move independently, you and a partner are less likely to disturb each other.
