Claim Text:
1. A chair assembly, comprising: a seat support structure operably coupled to a base structure, wherein the seat support structure is adapted to support a seated user thereon, and wherein the seat support structure is adapted to move between a first position and a second position; a back support structure operably coupled to the base structure, wherein the back support structure is adapted to move between an upright position and a reclined position; at least one biasing assembly exerting a biasing force that biases the back support structure from the reclined position towards the upright position, wherein the biasing force is adjustable between first and second magnitudes when the back support structure is in the upright position, and wherein the second magnitude is greater than the first magnitude; an adjustment assembly operably coupled to the at least one biasing assembly allowing a seated user to adjust the biasing force between the first and second magnitudes, wherein the adjustment assembly adjusts the at least one biasing assembly between a first configuration corresponding to the first magnitude of the biasing force and a second configuration corresponding to the second magnitude of the biasing force; and an assist feature exerting an assist force on the biasing assembly, thereby reducing an input force required to be applied by a user to adjust the biasing force from the second magnitude to the first magnitude along at least a majority of a full range of travel of the adjustment assembly.
