Perhaps nobody knows the importance of a comfy -- and ergonomically correct -- chair more than NASA astronauts, who often spend long hours strapped in their chairs in orbit.
From research conducted among Skylab crew members living in the orbiting station in the mid-1970s, it was learned that the human body, when at its most unstressed, assumes a trunk-to-thigh angle of 128 degrees.
This posture, studied in zero gravity, was found to place the musculoskeletal system in its most rested condition and foster an array of positive results: a non-stressed muscle system, correctly aligned vertebrae, better breathing, improved digestion, and enhanced circulation.
