The Silk Pillow Top Mattress has been designed to offer extra postural support without any compromise on comfort. The mattress boasts 2850 individually pocketed springs. The design allows the springs to move independently and helps to minimise motion transfer. The pillowtop layer, featuring an additional layer of mini springs, reduces stress on pressure points and helps to ensure spinal alignment. It is perfect if you like your mattresses comfortable yet firm. For Safety and Hygiene purposes, returns are not permitted on any mattress that is removed from original packaging.
