The transition layer is a crucial part of any new mattress purchase. This layer is often overlooked and is essential for the comfort and support your mattress. Purple's top layer is made from 1.8-pound polyurethane foam, which is shaped like a honeycomb. It has unique compression qualities and provides excellent spinal alignment and back support. While the cover of Purple mattresses is not machine washable, it can be spot cleaned with a mild detergent.
