Zero gravity chair recliner – The position of zero gravity , also called “Zero Gravity” , is the position designed by NASA for astronauts during takeoff, since it is the least pressure exerted on the spine and extremities. The position of zero gravity is rooted in research for the comfort and safety of astronauts, and is part of NASA’s program for the development of biomechanical systems that favor the maintenance of human body functions, productivity and ergonomics, as well as the quality of rest and sleep. One of the applications of the position of zero gravity are the chairs and armchairs called zero gravity, which are so named because they operate under the ergonomic principles developed by NASA
And in which the designers of zero gravity chair recliner take advantage of all the benefits of this technology. When seated in the traditional vertical position, acceleration forces are concentrated in the spine creating enormous pressure. Therefore, aerospace scientists looked for ways to prevent astronauts from suffering from the tremendous acceleration forces they are subjected to during the launch of rockets and ferries. During the takeoff phase of manned space flights, astronauts are exposed to enormous gravitational forces due to acceleration. These forces pose a great challenge for astronauts, since they entail a great compression of the disks that separate the vertebrae from the spine.

Zero gravity chair recliner position minimizes the effects of these large acceleration and gravitational forces. This position does not simply consist of reclining or lying down in a horizontal position, but it is about sitting in a totally reclined position with the feet higher than the head, in such a way that the different parts of the body adopt very specific angles. Other beneficial effects of the position of gravity are its ability to relieve muscle tension, increase lung capacity, reduce pressure on the heart and even increase oxygen levels in the blood.
