Paired with a mobile swivel base on castors, this version of &Tradition’s shell chair made from 100 percent recycled plastic comes completely custom-upholstered. Rely, the updated version of a Nordic standard from designer Hee Welling, offers a choice of premium fabric or leather covering over a layer of resilient HR foam to go with its sleek appearance and ergonomic contours. The swivel base with rolling castors is made from extruded aluminum and is available polished, bronzed, or powder-coated black.
