Abstract
A chair seat and supporting base for the seat, each of which can be of unitary construction. The base is formed from a plastic material and has legs, the side walls of which merge smoothly into depending peripheral skirts of an upper supporting portion of the base. The legs have a plurality of vertical strengthening webs which are unexposed when the base is in its normal upright position. In addition, there is a grid-work of longitudinal and transverse walls each of which is vertical and which provide additional beam strength and rigidity to the base. Several arrangements are provided for securing a seat-back shell to different embodiments of the base. A unique glide arrangement is also disclosed which permits severing the legs at a desired height to provide chairs of different heights while providing a flat floor engaging glide that is secured against removal, for example, by ultrasonically bonding the glide to the foot of the chair leg.
