21ST CENTURY ERGONOMICS: The $8500 Smart Office Chair That Never Stops Moving. “Dr. Patrik Künzler believes chairs should instead encourage small but constant motions that are good for the body. He spent six years developing a product to challenge the convention that a comfortable chair should have a flat seat and a back. The $8,500 LimbIC chair, released in 2011, incorporates ergonomics and neuroscience to stimulate not just the body, but also the emotions.”

A little pricey.
