Note: I got this video from a Vimeo page by someone named Designboom, Last night (12/11/15) I was contacted by the original producer of this cool animation. He gave permission for me to leave it up as long as I mentioned his company, Best Reviews and included a clickable link. I am totally in love with this so please feel free to check it out on their website. The top of the page has reviews of desk chairs. You will have to scroll down to the bottom to see a larger version of the Evolution of the Desk.
Thank you, Mr. Faw. This is truly cool!
