Reverberation is a flexible and responsive chair built for years of ergonomic comfort. Designed to offer support over both your lower and upper back regions, the flexible nylon back and waterfall seat design help keep you alert, while effectively distributing the weight of your body. The pneumatic lever and tension control knob fine-tune the chair’s height and tilt to personalize Reverberation, while the pivot and height adjustable armrests make sure your upper-body is well-positioned. Although nylon designs have increased in popularity in recent years, Reverberation offers a choice that is both stylish and works admirably well to protect your body from daily stresses. The aluminum base comes equipped with five dual-wheeled hooded casters for easy gliding over carpeted surfaces, and the molded foam seat pan comes generously padded for extra comfort.
