The Blue Sissel Sit Special 2 in 1offers comfortable, soft and upright sitting by relieving the spinal column and inter-vertebral discs. It is an ideal aid after injuries or operations. This support cushion has been designed with a unique bridge and anatomical depressions to improve the quality of sitting and alleviate the sacrum and coccyx. Made from high quality polyurethane foam combined with a removable visco-elastic foam coccyx pad, it offers a perfect pressure balance and its rubberised underside prevents sliding, even during long sitting periods.
