CHAIR SHELL WITH SELECTIVE BACK STIFFENING ABSTRACT OF THE DISCLOSURE A shell construction is provided for seating, such as chairs and the like, and comprises a semi-rigid, resiliently flexible sheet, having a generally L-shaped side elevational configuration. The sheet has a bottom shaped to support a buttock area of an adult user, and a back with a central area disposed directly behind a lumbar area of a seated adult user to support the same. An upper area of the back is disposed generally behind an upper back area of a seated user to selectively support the same. At least one rib is formed integrally on the rearward side of the sheet, and extends generally vertically along the central area of the back to stiffen the central area of the back in a vertical plane for firm support of at least the lumbar area of the seated user, yet permit at least the upper portion of the back to flex in a horizontal plane for improved freedom of movement of the upper back area of the seated user.
