Custom-upholstered with a matching seat cushion, this variant of Rely is paired with a handy swivel base. Designer Hee Welling’s breakthrough shell chair made of 100 percent recycled plastic underpins the choice of premium fabric or leather over a layer of HR foam to offer ergonomic comfort as well as a strikingly made-to-order appearance. Made of extruded aluminum, the swivel base comes in a chrome, bronzed or powder-coated black finish.
