ABSTRACT:
A chair is operable between a seating position and a rise-assist position. The chair comprises a base; first and second legs; a seat pivotally connected to the first and second legs; and a back pivotally connected to the seat. The chair further comprises first and second members pivotally connected at a first end to the legs, and pivotally connected at a second end to the back. At least portions of the legs, first and second members, back and seat form first and second four-bar linkages, respectively. At least one biasing member is pivotally connected at a first end to one of the base and at least one of the legs and pivotally connected at a second end to at least one of the four-bar linkages. The at least one biasing member operates to assist movement of the chair between the seating position and the rise-assist position.
