ABSTRACT:
A stackable utility chair embodying interlocking side bar members which function to releasably interlock together adjacent chairs of identical configuration to form semi-permanent rows. The side bar members also function to positively align the chairs during vertical stacking and, due to their unique Z-shaped cross-sectional configuration, provide substantial lateral stability to the stacked array.
