Zero gravity refers to an ergonomic position or setting that simulates the sensation of weightlessness. This is done by evenly distributing the user's body weight and putting them into a neutral position designed to provide optimal comfort and support.

By elevating your legs over the level of your heart, proper circulation is increased, helping to reduce swelling as well as minimizing stress on your heart. The strain of gravity on your vertebrae is also greatly reduced. Using a zero gravity chair for just 20 minutes has the same restorative effect on the spine as sleeping for 10 hours straight. (Not recommended for clients with vertigo or inner ear issues.)
