CHAIR 23D 2009 Materials: 18mm birch-plywood Cushions (fabric, foam, 3mm birch-plywood) The Space-Frame series are furniture designs developed between 2008 and 2011, which are based on space-consuming structural elements (space-frame). The aim was to test architectural principles of scale, structure and production on a real object. Digital and manual techniques have been researched and developed in a series of prototypes. The resulting furniture was produced in small series with a network of workshops and distributed in a small, limited series. The Chair23D is based on the typology of a lobby chair, similar to the Barcelona Chair by Mies van der Rohe. The complex three-dimensional structure can be assembled without glue or screws to form a stable, self-contained system. The construction is an extension of the human skeleton, with a spine connected to a series of ribs and a kind of pelvis from which the rear legs are held.
