The machine typically consists of a large, flat, circular rotating table on which the chair base is secured. The upper part of the chair is loosely fixed to allow the base to rotate around its axis. Weights are applied to the seat to simulate a user’s load (e.g., 60 kg to 102 kg). The table then rotates the chair base for a specified number of cycles, which can be set for a high count, such as 120,000 rotations or more
