Layer Details
Soft knitted sleep surface
A soft, breathable knitted cover that adds a plush feel. It gives you a comfortable first touch without making the mattress feel soft overall.
Soft white fibres
A filling made from 100% polyester that offers good recovery and is very durable. It keeps the surface comfortable for longer.
Traditional memory foam
A memory foam layer that contours to your body to relieve pressure points. You get personalised cushioning, which helps at the shoulders and hips.
Staycool gel memory foam
A gel memory foam that gives cooling comfort and gentle pressure relief while helping manage moisture and regulate temperature. It's there to keep you feeling fresher through the night.
Mini pocket springs
A layer of mini pocket springs working alongside the main spring system. It makes the surface supportive and responsive, so you're not sinking too far into the foam.
Pocket springs
Up to 1,800 individually pocketed springs in a king size, each working independently. They give better pressure-relieving support and limit how much you feel a partner's movement.
