The open geometric framework with its irregularities and jagged edges on the back of the Vinton Sand Chair suggests handcrafted iron work. In a gilt bronze finish, the wrought iron shimmers with a golden patina. The F0217 Appeal Sand fabric upholstering the seat is made up of 62 percent polyester and 38 percent viscose. Cleaning code: S. The Vinton is also available covered in muslin, and as a room screen.
