While I agree with other commenters here that this setup probably isn't a good idea for most people, I want to go out on a limb and say it seems to me the author may have good reason to have undertaken such a project (he specifically mentions that this article is NOT about his motivations). Specifically, just profiling based on the apparent age of the gentleman in the photos, I would not be surprised if this reason was some sort of injury, arthritis, or similar source of pain caused by ordinary sitting-at-a-desk posture. All that is to say, good for him for making a thing that seems to work for his needs, and shame on people jumping to poo-poo this because it's not solving a problem they personally have.
