Abstract
Abstract A seating unit that includes two side support assemblies and a plurality of lateral connecting rods which are received in mounting apertures through the side assemblies. A securing clip is received inside the hollow ends of each lateral connecting rod to prevent the side assemblies from separating. Each clip has a pair of extending legs with a locking tab that seats in a recess within the lateral rod. The lateral rods flex under the weight of a person seated on the seating unit in order to create a frictional locking force between the lateral rods and side assemblies to prevent the side assemblies from sliding toward each other.
