Aching Back? Sitting Up Straight Could Be The Culprit offers an interesting light on the problem of our aching backs. Some doctors in Scotland use magnetic resonance imaging (MRI) equipment to study the biomechanics of sitting posture to see if they could determine the optimal posture. They showed that sitting in an upright position places unnecessary strain on your back, leading to potentially chronic pain problems if you spend long hours sitting.

Their observation is that our bodies did not evolve in with a 90 degree body-thigh angle in mind. Instead the optimal body-thigh angle was found to be 130 degrees. In other words those kneeler chairs are pretty close to an optimal body-thigh angle. Another kind of chair that would be beneficial is one whose back reclines easily.
