Modular through and through: The new Costume sofa system from Stefan Diez is pragmatic, transformable and protects resources – it’s the easy-going companion we wish for today.
At the heart of Costume is a body made from recycled and recyclable polyethylene produced using rotational-moulding technology from furniture and car industry waste. An insert made of pocket spring cores provides the cushioning for the seat and backrest. On top of this is a thin layer of polyurethane foam. The whole is held together by a cover made of fabric that can be fastened on using tension belts and easily removed at any time. Not only does this system use much less foam in manufacturing than conventional sofas – most of the materials used can also easily be recycled. If the upholstery wears out one day, it can easily be replaced.
Growing up in a household of 4th-generation carpenters, Stefan Diez’s early bond with craftsmanship profoundly shaped his development as an industrial designer. Following family tradition, he trained as a cabinetmaker before studying industrial design under Richard Sapper at the State Academy of Fine Arts Stuttgart. Working with Konstantin Grcic for several years, Stefan graduated in 2002 and founded DIEZ OFFICE in Munich. From 2007 onwards Stefan was Professor of Industrial Design at the University of Arts and Design Karlsruhe, joining the School of Industrial Design Lund, Sweden, in 2015. Since 2018 Stefan Diez is Head of Industrial Design at Die Angewandte in Vienna. In 2008, DIEZ OFFICE moved into the renovated premises of a former joinery, the ideal platform for Diez’s distinct combination of hands-on experimentation and technical know-how. Led by curiosity and supported by a network of local craftsmen and specialists, DIEZ OFFICE is dedicated to transforming ideas into actual products with great diligence and proficiency. Together with his team, Stefan Diez has been exploring a broad spectrum of design, creating award-winning furniture, luminaires and accessories, in collaboration with internationally renowned manufacturers like Rosenthal, Thonet, HAY, e15, Magis, Vibia, Viccarbe, Wagner and many more.
