Not only does the Rolled Open Spring Double Memory Mattress provide you with a firm level of support thanks to its Airsprung Supercoil spring unit, but it also offers added comfort with its luxurious 30mm layer of heat-sensitive memory foam. The entire mattress is finished with a white woven damask to add to the luxurious sleeping surface, and the mattress has even been rolled so it's easy to transport. Although this mattress doesn't need to be turned, it is recommended to rotate it from head to foot in order to ensure even wear. Suitable for a 135cm double bed.
