Abstract
A basic chair frame is disclosed consisting of a minimum number of interchangeable components including a seat/back frame member, a spindle attachment plate a seat shell and an anti-racking attachment for arm members. Because the several parts are reduced in design and construction to basic essentials by means of interchange of components the frame can be modified to adapt the chair to a variety of disparate uses.
