Q. How long should you sit in a zero gravity chair?

Answer

The zero gravity position helps alleviate back pain by redistributing the body's weight and keeping the legs above the heart. Using a zero gravity chair for just 20 minutes a day has the same restorative effect on the spine as sleeping for 10 hours straight. However, when we sit for long periods of time, we compress our spinal column significantly more than we would under normal circumstances. In addition to the obvious effects of sitting for lengthy periods of time on the body, improper seating patterns like slouching and leaning forward can have a cumulative and deleterious effect.
