Abstract
Abstract The seat and back of a seating unit are each formed of a plurality of cushioned upholstered elements which extend between a pair of L-shaped support members to provide continuous back and seat surfaces. The L-shaped members have an elliptical cross section which includes two hollow semielliptical portions, a central wall connecting these portions, and two longitudinal channels on opposite sides of the central wall. The upholstered elements are attached to the L-shaped members by plastic guiding strips which ride in the channels.
