Abstract
Abstract Tables and stools of inexpensive and simple yet rugged construction are made from plate members spaced by a hollow post and held in assembled relation by a single draw bolt. The plate members of the disclosed stool are both disc-shaped and a seat back is optionally secured to the upper plate member. The disclosed lower plate member of the table is formed with four horizontally projecting legs. Stiffening ribs and supplementary supports are also provided when the table top is so large as to require additional support. All of the parts of the tables and stools are so designed that various heights and diameters of tables and stools can easily be made.
