Supports sitting upright and alternates with other seating, you can do his back something good. Alternatively, sitting with cushions or standing on a height-adjustable desk I can spend in the office long hours without any problems. If you sit a long time on it, you start to sweat, even on the dimpled surface. But remains bearable and still better than back pain. Keilkissen I felt as uncomfortable, another cheap seat cushion that I have tried, had a hard-cornered very uncomfortable edge. Overall recommended.
