We purchased this side table/stool at Cisco Home in Pasadena. This piece and a similarly-designed coffee table were just two samples of collapsible furniture made by a local design collective called Fend.
The stool’s design is simple and perfect. Four solid pine pieces fit together like a puzzle and are secured with two mahogany pegs. As I understand it, Cisco Home is considering carrying them in birch, walnut and a variety of reclaimed woods.
