It is uncertain as to what year zero gravity chairs came into existence but most people believe that the earliest consumer versions were released in four years ago. This kind of furniture is also referred to by many as anti gravity chairs. The uninitiated upon hearing the term zero gravity chairs will likely think of these pieces of furniture as capable of hovering or floating. The name ascribed to these chairs is a somewhat a misnomer because they don’t actually defy gravity, instead they are highly adjustable chairs which are designed to support the human body extremely well, creating a sensation of weightlessness.
