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. 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.
