Zitten is een werkwoord / Sentarse es una acción, Rietveld voor IMPA : Over de relatie tussen kunst, arbeid en het dagelijkse leven.

IMPA is a metallurgic factory in Buenos Aires. That after closing down during the Argentine economic crisis, was ‘taken over’ by the workers, and till today functions as a cooperative. In June 2010 the workers at IMPA, with the help of teachers, local residents, and artists, founded a university known as the University of the Workers within the factory walls. Aimée Zito Lema and Nahuel Blaton setted up an art project in which 100 Rietveld chairs were assembled at the IMPA factory by more than 80 volunteers to be used by the students of the university.
