Separate power drive mechanism (7) (8) concurrently move the user support (2) and rotate the members to omni-directional user movement. A control (4) for the power driven mechanism (7) (8) is responsive to the directional orientation of the user on the user support (2) to cause the user support (2) to operate in the direction of the orientation of the user (3).
