Ruckus Chair, KI
This flexible chair allows students to sit in any number of ways on its unconventional diamond-shape seat. The Ruckus chair is available as four-leg or stack chairs, with casters or glides, at 15" or 18" tall. An optional book rack under the seat provides additional storage, while the backrest of the chair offers a perch-able surface for less formal interactions. The seats and backrest are made of fiberglass-reinforced polypropylene with a steel frame that can be nickel-chrome plated or powdercoated. ki.com
