ergoCentric Seating Systems Inc. has produced a 17 minute video entitled "The Anatomy and Biochemistry of the Human Body in the Seated Posture". This video contains no advertising whatsoever. It discusses the benefits of the seated posture as well as the stresses this posture causes. It then reviews the features a proper chair should have to reduce those stresses and make you healthier and more productive.

After watching this video you will have the information you need to make an informed decision when purchasing an office or industrial chair. It might even get you to use the adjustments on the chair you're sitting in right now! A very positive review of the video was published in a Communique of the Human Factors Association of Canada. The video is available in VHS and CD-ROM formats.
