Abstract
A chair includes a seat portion; a backrest surrounding at least a portion of the seat portion; and a base removably positioned beneath the seat portion. The base preferably includes tapered sidewalls that correspond with the backrest when the base is inverted and placed on the seat portion. In such a nested position, the disassembled chair may be efficiently shipped and stored in polyhedral boxes with angled side walls, that may be stacked and alternatingly inverted to take advantage of the angled sidewalls of such boxes.
