The luxurious SmartSleep Memory Pocket 1000 Mattress is made up of 1000 foam encased pocket springs with a 50mm top layer of zoned memory foam and a high density support foam base. Individual pocket springs work independently to provide support and even pressure distribution as you sleep. The springs are encased in high density foam, giving edge to edge support and maximising the sleeping surface. A top layer of pressure relieving memory foam has zoned areas for added comfort and support in all the right places. This mattress features a beautifully soft four way stretch knit cover with Adaptive&reg technology which, along with a breathable mesh border, helps keep you cool and dry at night. A Fresche&reg Bioscience high performance antimicrobial finish inhibits house dust mites and helps fight bacteria and odours. This mattress is made to standard in the UK and comes with a full 10 year structural guarantee for your peace of mind. It is delivered vacuum packed and rolled for easy transportation. Once unpacked, just give the mattress a few hours to fully expand. Please note: Spring count refers to a 5ft Kingsize model.
