Modular furniture includes several members connected together without fasteners or other hardware. While some of the members slide together, some members are locked in place by other members. The modular furniture includes one or more members that engage other members in a twist and lock fashion that helps hold the modular furniture together during everyday use. The twist and lock may be achieved using a substantially L-shaped slot in one member and a corresponding slot in a mating member, which allows the mating member to rotate (twist) within the L-shaped slot. The modular furniture is locked together at several different members and stages of assembly, and includes a final stop member that assures the furniture cannot come apart inadvertently during normal use.
