Zero gravity technology was initially developed by NASA as a way to help relieve the tremendous amount of pressure that is exerted upon the back of astronauts when they lift off toward space. Zero gravity Massage Chair companies soon started replicating this same technology allowing the massage chair to simulate a completely weightless experience similar to the zero gravity experience of an astronaut in space. A Zero Gravity Massage Chair allows your body to disperse all weight and tension throughout the chair, while prompting a feeling of weightlessness that relieves stress, tension, and muscle discomfort. To feel this weightlessness, the chair only has to have a 30 degree tilt up.
