The 637 Utrecht lounge chair, designed by Gerrit T. Rietveld in 1935 for Cassina, is a masterpiece of constructivist design. Originally created for serial production at the Metz & Co. department store in Amsterdam, the chair features bold geometric armrests that contrast with the soft, inviting curves of its seat and backrest.

Upholstered in fabric with distinctive blanket stitching or in leather, the chair’s clean lines and innovative form make it a timeless icon. Its steel frame and polyurethane foam padding ensure comfort and durability, while its modernist design continues to captivate, blending architectural precision with everyday usability.
