The ultra low weight Vicair® SMS Cushion was designed specifically for use following procedures such as perianal surgery, difficult childbirth or for patients suffering localised pressure sores, where any contact on the affected area when sitting has to be avoided. Vicair's patented air cels can be individually adjusted and removed from a centre circle to remove the area of contact, with the user still retaining overall stability and pressure relief.
