The Red and Blue Chair is a seminal work of De Stijl design, originally created by Gerrit T. Rietveld in 1918 and faithfully produced by Cassina. With its bold use of primary colors and intersecting planes, the chair transforms geometric abstraction into functional art. Its precise construction in solid beech and multilayered lacquer celebrates both craftsmanship and avant-garde design ideology. As a collector’s icon and sculptural statement, it remains one of the most recognized pieces of 20th-century design.
