In 1918 Reitveld joined the De Stijl movement which had sprung up around the review of that name founded the year before by Van Doesburg, translating certain laws of composition that had already been expressed by the Cubists. The De Stijl artists also carefully studied the architectonic lesson taught by Frank Lloyd Wright whose influence was widely felt in Europe at the time. Among Reitveld's most important works are the Zig Zag, Utrecht and Red and Blue chairs, all sold by Aram Store.
