Abstract
A chair comprises a seat pan member, a seat back member having a lumbar support member, a lumbar support assembly operatively connected to the lumbar support member and configured for moving the lumbar support member, with respect to the seat pan member and the seat back member, between at least a first position and a second position, and an actuator configured to operate the lumbar support assembly for movement of the lumbar support member between at least the first position and the second position. When the lumbar support member is in the second position, the lumbar support member is positioned forwardly, in a direction toward the seated user's lower back, relative to the seat back member so as to enable the user to be seated forwardly on the seat pan member while being engaged with the lumbar support member.
