Gerrit Rietveld, Red Blue Chair, 1923
Although the chair was originally designed in 1918, its color scheme of primary colors plus black—so closely associated with the de Stijl group and its most famous theorist and practitioner Piet Mondrian—was applied to it around 1923. Hoping that much of his furniture would eventually be mass-produced rather than handcrafted, Rietveld aimed for simplicity in construction. The pieces of wood that comprise the Red Blue Chair are in the standard lumber sizes readily available at the time. MoMA.
