A back construction includes a back shell having stiff thoracic and pelvic regions connected by a flexible lumbar region in a manner adapted to ergonomically support a seated user. The back shell includes springs that press on a rear surface of the back shell to bias the flexible lumbar region forwardly so as to support a seated user, thus biasing the lumbar region of the back shell forwardly in a manner distributing stress applied to the lumbar region by the seated user.
