Gerrit Thomas Rietveld was a young rationalist architect in his thirties, active and committed, when he joined the De Stijl movement in 1918.

The movement tended to translate and compose in ideology the theme of dynamic breakdown and decomposition that had already been expressed in cubist painting.

When Cassina wished to have some of Rietveld's work in our historical catalogue, the Rietveld family lent its support and, in 1972, Cassina was granted exclusive worldwide rights to produce and market furniture and other objects designed by G.T.Rietveld.
