USM HALLER library consists of four open metalled ements. It is part of a system of modular units designed starting from architectural structures combining elegance and technique together. A spherical joint in chromed brass is the core of the Haller system with chromed steel tubes. Between the joints and tubes are mounted the powder painted metal panels (11 colours available) and dividers. This system has been acquired and exposed in the Museum of Modern Art in New York.
