In this video on posture (part two of a three part video series) I focus on how to adjust your office chair to suit your height and look after your lower back.

A good office chair should go up and down the back support should go up and down as well as in and out. Your feet need to be resting and at a 90 degree angle – watch the video so you can clearly see how I adjust the chair.

If you are under five foot five there is a very good chance you will need a foot rest in order to get your body at a 90 degree angle.

This video features a talk that I often do which is part of our corporate health and wellness program. If you would like me to come in to your organisation call the Active-X offices on 0131 221 1415
