Abstract

An articulated back-to-back fold-down chair seat and side-rail track construction wherein the seats are mounted on slides which telescopically engage associated rails affixed to a chair platform support. The rails and slides have an interfitting cross-sectional configuration. Each seat has a stop with a dependent leg protruding downwardly within the confines of the platform to limit the movement of the chair in the fold-down couch position.
