Abstract A modular seating arrangement comprises a plurality of interconnected bases, each defining a pair of female sockets therein. A seat, disposed on the base, has a pair of releasable male fasteners secured thereon which engage within the female sockets. Each male fastener comprises an elongated member having a bifurcated end defining a pair of split locking portions which are expanded into interlocking relationship within a respective one of the female sockets. Back, arm and/or table components may be secured on the base to complete the modular seating arrangement.
