How about an ergonomic chair with a self adjusting back? It works with 11 spring loaded vertebrae that automatically, adjust in and out, following your back left & right for comfort all the way to the bone.
The Verte ergonomic chair was inspired by the human vertebrae, and takes its shape from you providing you with excellent support to reduce back pain. Introduced in September 2004 It was the first self adjustable office chair. Charles Caleb Cotton said ... "Imitation is the sincerest of flattery." We agree. Herman Miller introduced an imitation to the Verte chair called the Embody chair in early 2009. Reviews by Entrepreneur Magazine, Houston Business Journal,Dallas Business Journal,Mac Directory News.
