You missed the crucial detail that they make it uncomfortable to force people to sit back and lean against the back. Then is stops being uncomfortable, and if the posts til now have been on the right track, it makes the chair meet some kind of weight threshold. Sitting back is great for an audience.. Not so great if you need to work in front of you on a desk, bench, or table.
