Theo Van Doesburg was somewhat eclipsed after the De Stijl period by the growing reputations of Mondrian & Rietveld.

Although thought of more as an artist & theorist, Van Doesburg involved himself with most areas of design with skill. Little known is that he also designed some interiors & furniture, such as the following chairs.
