The Designer Ring Cushion is made from visco elastic memory foam, which makes this ring cushion both incredibly comfortable and supportive for the user and helps to reduce the discomfort of prolonged sitting. The cushion allows the user to sit comfortably for longer periods than usual as the elastic memory foam conforms to the shape of the body and literally moulds as you move reducing the interface pressure on the user. The Designer Ring Cushion is suitable for use with those at "high risk" of pressure sores and comes fitted with an inner cover.
