The swivel mechanism has an upright post mounted on the base, a horizontal shaft fastened pivotally at one end to the upright post, a horizontal support tube rotatably fitted over the horizontal shaft and provided at one end with a connection bar, and a link rod connected at one end with the connection bar of the horizontal support tube by a first universal joint, with the other end of the link rod being connected to the base in conjunction with a second universal joint. The two footrests are supported respectively by a tilted arm on the horizontal support tube such that the two footrests are capable of vertical and horizontal motions at the same time.
