To use the prostration-mat as a sitting support, open the carrying belt on the side where the buckle is located to form a large loop and pull the other side of the belt together. Fold the mat so that one part becomes the backrest and one part becomes the cushion, step into the loop and place it around the mat and your knees or foot. In this way it becomes possible to stabilize and support one's back by the countertraction. The tension of the support can be adjusted by means of the buckle. This makes sitting in a confined space very comfortable.
