The Steltman Chair was designed in 1963 by Gerrit Thomas Rietveld for Steltman Jewellers. Created for the jeweller’s showroom, the chair was conceived in two mirrored versions placed beside a display case where customers could sit while choosing wedding rings. Its construction reduces the chair to a strikingly minimal structure of intersecting wooden planes, forming an elegant balance between geometric clarity and structural ingenuity. The design reflects Rietveld’s lifelong exploration of spatial composition and abstraction, rooted in the principles of the De Stijl movement, where furniture becomes a composition of lines and planes rather than a traditional object. As one of the last chairs Rietveld designed, the Steltman Chair embodies a refined and mature expression of his modernist vision.
