Designer Hee Welling’s breakthrough shell chair made of 100 percent recycled plastic gets an extra spin of efficiency when paired with a 4-star swivel base. Rely takes the Scandinavian classic and gives it a timely update while honoring its ergonomic attributes and molded contours. It’s available in a range of select colors with the extruded-aluminum swivel base in a chrome, bronzed or powder-coated black finish.
