This slick MCM stool is constructed of a fiberglass shell supported by a painted black metal tube and four metal legs. The metal is iron or steel, but difficult to qualify with the paint. The shell of the chair is visibly woven wheat rattan under fiberglass. This stool has three adjustable heights and swivels making it a good choice for a workshop, garage or art studio. The height of the stool ranges from 17 inches at its lowest, and 23 inches at its highest. This cool mid century modern work stool has a killer profile and minimal signs of wear appropriate for age and use.
