Chair ergonomics. Series of artworks of human skeletons, showing the correct posture for a human when sitting on different types of chair. In all four, seen from different angles, the spine is kept in the correct position, with lower lumbar support where needed. The first chair is suitable for short periods of sitting. The second chair can be adjusted to fit people of different heights, and is used in offices. The third type is used for relaxation. The fourth type is adjustable, but lacks a back-rest. For the same artworks, but with the muscles included, see image C010/2803.
