Firmer orthopaedic support is cleverly achieved in this mattress by combining supportive pocketed springs with generous layers of luxurious natural cotton fillings. 1500* Pocket Springs - Pocket springs move independently and so provide the best postural support. The individual pocket springs follow and support your body shape and weight. *King size. Firm Edge Support - Firmer springs along the sides add strength to the edge of the mattress to allow you to use the whole surface of the mattress as a sleeping area. Cooling Natural Cotton Blend - Cotton is combined with soft white fibre into a deep layer. Cotton is breathable, highly absorbent and is excellent at controlling body temperature through its moisture wicking properties. Hypo-Allergenic Superflex Foam - Designed to provide excellent levels of comfort and support. Dust mites cannot survive in the foam, allowing a healthy environment and peaceful sleep. Durable Cotton Foundation - This cotton layer is designed with responsive rebound properties that complement the pocket springs to help provide the most comfortable feel. Turntable - Both sides can be used prolonging the life of the product. Turn over and rotate your mattress once a week for the first 3 months and then once a month thereafter. 3 Rows of Side Stitching - Provides a more robust mattress border than a standard mattress. Traditionally Hand Tufted with Wool Tufts - This traditional skill ensures all loose fillings are secured to provide the perfect finish to your mattress. 8 Year Guarantee - For your peace of mind, Relyon offer a 8 year guarantee on all mattresses purchased with a divan base.
