Created from 8000 chopsticks, the Yuya Ushida ‘XXXX_SOFA’ is a masterwork of inventive engineering. Press following its debut praised of the ingenious construction that allowed for conversion from sofa to chair and an assembly process that necessitated 10,000 connections and took three and a half months to complete.

Ushida used bamboo chopsticks to create the prototype ‘XXXX=SOFA’ for his graduation project at the Design Academy Eindhoven, the present lot from small subsequent production in injection-moulded plastic.

There are three examples of the 'XXXX_SOFA' in permanent museum collections including: Vitra Design Museum, Weil am Rhein; The Museum of Modern Art, New York; and one version executed in bamboo at the Victoria & Albert Museum, London. A further two examples are within private collections.
