The concept for the Neutral Posture chair was developed by Jerome Congleton, PhD, PE, CPE. From our state-of-the-art Neutral Posture® series to our line of N•hancements® accessories, our products are based on the concept of neutral body posture. This natural, stress free position is the body's preferred posture, similar to the free floating posture experienced when you totally relax in a swimming pool, or the posture typically associated with astronauts floating in space. Neutral Posture products were developed to help users emulate the body's preferred position while they work, because it is in this posture that the body achieves equidistant spacing of the vertebrae and an ideal balance in the muscles, tendons and ligaments.
