With convenience and utility in mind, &Tradition offers its sustainable molded armchair with automatic gas lift and a 5-star rolling base with castors. Designer Hee Welling's breakthrough take on Scandi molded seating is made from 100% recycled polypropylene, curving around the body and extending out along the sides for comfortable back support. The swivel base with castors is made from extruded aluminum, in a polished finish or black powder coat.
