This is the Marquess Mattress, a great new addition to Relyon's Heritage Collection. With a pocket spring count of 2200 in the king size model, this mattress offers a superb balance of comfort and support. Pocket springs consist of independantly moving springs in individual fabric pockets. This spring system has two layers helping the mattress to move to the contours of your body, helping to bring support in key areas where you need it the most. Hand tufted in a traditional way, the Marquess will be sure to retain plumpness long into its lifespan. The sides have been carefully hand stitched with three rows to ensure edge to edge support. Silver+ Protection is a coating based on microparticles of silver ions. It helps to combat and dramatically reduce microbial growth providing a fresh and hygenic fabric. The fillings are made from hand teased mohair, lambswool and hand teased lambswool, all renowned for their high levels of comfort.
