Abstract:
This study investigates the criteria defining sit-standing postures offered by Chairless chair devices through comparative analysis. It evaluates the applicability of conventional sitting posture criteria, including balance, body segment orientation, and biomechanics, in defining unconventional postures. Findings indicate that sit-standing postures exhibit a distinct center of gravity, unique support polygons, and specific body segment geometries. Devices such as those developed by Noonee and Archelis facilitate a posture that is intermediate between sitting and standing, enhancing visual control and interaction with the workspace. This research underscores the potential ergonomic and functional benefits of these innovative seating solutions, warranting further exploration
