The One Way Slide Sheet is designed to be used as a moving and handling aid to help position the client so their pelvis is upright and supported in the back of a chair. It only rolls freely in one direction, completely locking to stop the client sliding forward, thus preventing them from sacral sitting. It has an integral visco elastic foam cushion to provide pressure relief for low to medium risk clients. This cushion means that the slide sheet is comfortable to sit on and can be left in place beneath the client, helping them to maintain their correct sitting position.
