The Handkerchief chair, with metallic tubular structure and fabric seat upholstery, is designed by Vignelli Designs for the brand Knoll. Vignelli Designs brought elegance and design to the too-often styleless chair with Handkerchief. Intended to evoke the windblown contours of a handkerchief floating through the air, the generously scaled, ergonomically sculpted shell offers spacious comfort and ample support. The seat and back are a unique piece of moulded plywood and upholstered with fabric in many finishes.
