Sitting straight upright is not the best sitting posture, say researchers

The best sitting posture is not sitting bolt upright, but leaning back, with a 135 degree angle between your thighs and your torso. That’s the judgement of researchers who used a new form of magnetic resonance imaging (MRI) that enabled them to determine the weight-bearing strain being placed upon the spine. The study was conducted at Woodend Hospital in Aberdeen, Scotland.
