The Slumberland Essex mattress uses a European 5-zone support system with independently pocketed coils. This zoned pocket coil spring system helps to minimise sleep disturbance caused by the movement of other sleepers. The all-important comfort layers of the Slumberland Essex are made of high-resilience comfort foam, premium memory foam and gel-infused memory foam. The Essex mattress is topped with a Hi-loft, wool fibre blend for added comfort.
