With specially created coil-springs, each with their own calico pockets and contained by a high-tensile webbing to ensure complete compatibility with the profiling action, the Pocket Sprung Supreme is a wonderful mattress. Carefully manufactured with a generous 50mm layer of memory foam and for those requiring a soft-medium pressure relieving qualities, this is one of the most comfortable mattresses available. Edge zoning makes the outside edge of the mattress is firmer, making it easier to transfer to and from the bed whilst leaving the centre of mattress softer for sleeping.
