Leap is a highly ergonomic chair that is the first to feature dynamic back support (LiveBack technology) that changes shape to conform to your back as you move in your chair.  The chair uses a synchro-tilt mechanism coupled with  a gliding seat. As you move and recline, the seat glides forward slightly lifts up. It  means that as you move in your chair, you stay oriented, never leaving your vision and reach zone. Even when leaning forward, the seat edge flexes to relieve pressure on the back of the legs. In the leap, you can work as long as you like, without feeling uncomfortable and losing productivity.
