The Bertoia Bird Ottoman, designed to pair with Bertoia Chairs (sold separately), but easily able to fly solo, is a natural extension of Harry Bertoia's sculptural designs for Knoll. It's welded from strong steel rods and upholstered in a range of fabrics. The cover attaches directly to the frame with hidden metal hooks and can be removed for cleaning. The frame is stamped with the Knoll logo to ensure authenticity. Made in Italy.
