ABSTRACT:
The present invention entails a chair having a back movable between an upper operative position and a lower or retracted stowed position. The chair includes a base frame having a seat and a catch rail disposed below the seat. A retainer is spaced above the catch rail and there is defined a throughway between the catch rail and the retainer. A back is provided and is movable relative to the base frame. In the upper operative position the back engages and is supported by the catch rail while the retainer prevents the back from rotating past a predetermined position. In the lower retracted position, the back is disengaged from the catch rail and extends below the catch rail.
