I’m looking for a new office chair, something that will accommodate properly the number of hours I sit at my desk. I spotted these “Zero Gravity” chairs but you have to be skeptical when the advertising states “weightless relaxation just like the NASA astronauts during launch”. Does this mean when I sit in this chair I’ll experience double normal gravity pushing me back into it? Is it a 2xG chair? I”m pretty sure they meant “like astronauts feel once they have left the Earth’s gravitational pull” but even then I’m not sure I’d 100% believe their claims…
