This version of &Tradition’s reconceived shell chair made of 100 percent recycled  plastic has a swivel base with an efficient automatic return. Rely is Danish designer Hee Welling’s eco-friendly take on the classic Nordic molded chair, long prized for its ergonomic comfort and familiar curved profile. The seating is available in a range of select colors with the extruded-aluminum swivel base in a chrome, bronzed or powder-coated black finish.
