An ergonomic footrest comprises a chair attachment bracket for attachment to the underside of a work chair seat, a footrest actuating mechanism supported by the chair attachment bracket for rotational movement in relation to the chair attachment bracket, and a footrest mechanism including a footrest brace and at least one footrest support arm. The footrest support arms each have a first and second end. The first end of at least one support arm is attached to the footrest brace. The second end of at least one support arm is attached to the footrest actuating mechanism. The support arms moveably suspend the footrest brace in relation to the chair attachment bracket. Rotational movement of the footrest actuating mechanism causes the footrest brace to move in relation to the chair attachment bracket. Rotational movement of the footrest actuating mechanism is typically manually performed through the rotation of arm rests or hand grips which are integrated into the actuating mechanism. Alternatively, the actuation mechanism may include gas spring mechanisms. The ergonomic footrest may include two or four footrest support arms attached to the foot rest brace and the footrest actuating mechanism. The support arms, the footrest brace, and the footrest actuating mechanism comprise a parallelogram structure, which supports the footrest platform for curvilinear translation movement in relation to the work chair seat.
