The Zag Zig Chair by Möbel Link
The Zag Zig Chair is a surprisingly comfortable piece of furniture due to the inherent springiness of the structure. Sit in it and it responds to your movements. Whether you are rocking gently back and forth or side to side, or some combination of the two, this chair gently but firmly allows for movement. In fact, it is almost impossible to sit still in it; you just want to move! That's part of the reason for its other name: The ADHD.
