The Leap Chair V2 by Steelcase was built on a model incorporating the most ergonomic and comfortable features in contemporary seating technology. Its back changes shape to support the entire spine, its Natural Glide System allows you to recline and yet maintain your position so you stay oriented to your work. This encourages more varied postures so there's less static load on the spine. Tastefully designed Slats in both its back and seat promote thermal comfort and "breath ability," effectively controlling the balance of heat and moisture so you stay comfortable for long periods.
