Clad in customized upholstery, this version of Fiber comes with a swivel base on rolling castors and gaslift to instantly raise or lower the seat. Iskos-Berlin's side chair is a strikingly comfortable addition to a home or workspace, molded from a next-gen plastic with 25% wood content. And the 5-star base comes in powder-coated shades of black, white and grey or in polished aluminum.
