A recent study conducted at Woodened Hospital in Aberdeen, Scotland concluded:
A 135-degree body-thigh sitting posture was demonstrated to be the best biomechanical sitting position, as opposed to a 90-degree posture, which most people consider normal,” said Waseem Amir Bashir, M.B.Ch.B., F.R.C.R., author and clinical fellow in the Department of Radiology and Diagnostic Imaging at the University of Alberta Hospital, Canada. “Sitting in a sound anatomic position is essential, since the strain put on the spine and its associated ligaments over time can lead to pain, deformity and chronic illness.

Finally an argument supporting scoliosis!
I’ve become a huge fan of right angle seating posture primarily because of the effect poor posture can have on your overall posture later in life. It would be interesting to see if the results of this study vary based upon overall trunk length. I have a large torso which leads me to have more back pain if I don’t sit properly. Thanks for posting this info. Also, thanks for meeting up with me for lunch a couple weeks ago. It was good to see you and see that everything is going well for you.
Admittedly, I haven’t read the entire report, but the one thing they fail to discuss is proper angles when working on a computer. I’ve found recently if I recline, while still keep my back straight, my wrists don’t hurt as much either. Obviously, this is due to the fact that when I’m reclined my wrists are straight rather than bent backwards. It helps a lot!
It was good to see you too, I’m glad we were able to meet up, and again, congratulations!
