The Reaction task chair gives everyone – regardless of status, work style, or physical shape – the comfort and support that only comes with superior ergonomic design. The chair’s sleek profile doesn’t hurt its appeal, either. The heart of Equa’s design is a seat and back formed of a single piece of fiberglass-reinforced polyester. Its H-shaped cutout allows back and seat to flex independently, so the chair responds naturally to your movements. And it lets air circulate to relieve heat build-up.
