One of the most radical furniture designs of the early 1900s, Gerrit Rietveld’s Red/Blue Chair redefined traditional notions of form and space. Composed of rectilinear forms (in standard lumber sizes for ease of construction) and painted in primary colors (plus black), the chair was a three-dimensional expression of the De Stijl (“The Style”) movement, a group of Dutch artists who helped shape the cultural ethos and design aesthetics of the Bauhaus. Rietveld, a favorite among Bauhaus artists, was invited to exhibit at the Weimar school in 1923 and profoundly influenced designers like Marcel Breuer.
