A mobile patient chair includes a seat portion and an undercarriage coupled to and supporting the seat portion, where the undercarriage includes a frame having a set of rollers and a rocking mechanism coupling the seat portion to the frame. The chair has a rolling mode, whereby the set of rollers rotate and allow the mobile patient chair to move from a first location to a second location and a rocking mode, whereby the rocking mechanism is operable to move the seat in a substantially forward and backward translating movement relative to the frame. A lockout member renders the rolling mode and the rocking mode mutually exclusive.
