A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user.

A furniture device includes: a movable device; a height adjustment mechanism operably coupled with the movable device and configured for supporting the movable device in a plurality of positions including a lower position and an upper position, the height adjustment mechanism including: a ratchet defining a plurality of stations including a lower station and an upper station corresponding respectively to the upper position and the lower position; a rod configured for selectively engaging the plurality of stations; and a rod return device configured for pivoting and thereby for returning the rod to the upper station.
