This chair is the paradigm of ergonomic seating, conceived to conform not only to different body shapes but also to movement, with multiple adjustment points for a custom fit. The breakthrough Kinemat tilt mechanism lets it move smoothly with the user from forward tilt (when you reach for the phone) to backward recline (while you contemplate what to say). And the Pellicle weave upholstery, another innovation in concept and comfort, evenly distributes weight over the seat and back, and permits air circulation. Durable and sleek, this chair will still look like new long after you retire. Design doesn’t get more civilized. Constructed of 66% recycled materials.Backed by Madison Seating's 10 year warranty OnlyComfortable Suspension The strong Pellicle suspension system distributes weight evenly over the seat and back. Natural Tilt The tilt system lets people move naturally and effortlessly, from forward-leaning through reclining. . For help with your purchasing decisions please give us a call, a knowledgeable furnishing consultants is standing by to assist you.
