This chair allows people who work in a seated position for long periods of time to move in a natural way and readjust their posture, thus avoiding muscle tension. The seat can not only be rotated through 360 degrees on its own axis but can also tilt five degrees in any direction. This is thanks to an inbuilt, vertically positioned spring pin that can adapt to every movement. The seat with its raised edges and the firmly anchored base provide the necessary stability and secure support.
