We all remember the kid at school that could tilt his chair back at impossible angle without tippling over backwards. Well here’s an office chair that lets you do the same thing, just without endangering the back of your head. Recline, rock and even get some work done in the gravity balance chair, which provides a wide range of seating options.

The gravity balance is fully reclined. Your legs can be elevated above your head, and the feeling of floating free of gravity should be amazing.

The legs are bent in such a way as to feature three flat planes, so you can recline, incline or lay flat, simply by shifting your body weight. The integrated footrest also doubles as a kneeler so you can be comfortable in the forward position.
