The Memory Pocket Hybrid 2000 Memory mattress blends traditional pocket spring technology with the latest memory foam technology for optimum comfort and support. At the heart of the mattress we use 2000 individual 14cm posture support springs (based on the 150cm king size) that work independently to cradle your sleeping body. Then we use a layer of our advanced Cool Blue pressure relieving gel memory foam which helps dissipate heat and improves blood circulation for a restful nights sleep. A foam encapsulated border helps to provide improved edge support enhancing the sleeping surface of the mattress. The mattress is then encased in a luxurious heavy knit washable cover. The mattress has a medium /firm feel and has been designed for optimum comfort.
