Abstract
A seating unit illustrated as a mobile office chair includes a base, a back upright operably supported on the base for reclining movement and a back construction. The back construction includes a cushion assembly attached to a back support shell with quick-attach top and bottom connectors. Specifically, the back support shell includes top apertures, and the cushion assembly includes hooks for drop-in attachment to the top apertures. The back support shell also includes a molded bottom section defining a recess, and the back cover includes a stiffened edge flange configured to frictionally engage the recess to retain the back cover to the back support. The cushion assembly includes a cover assembly with an upholstered front panel, and a rear panel formed by a first sheet section having a one-directional stretch in a vertical direction, and a second section having a high-stretch property.
