Using a Stool

i got this idea from an alexander teacher named galen crance, whois a professor of architecture. She wrote a wonderful book about ten years ago called the chair. And she also talks about the advantage of having sitting in a chair that's a bit higher than the nor one. i would never use a chair sitting at a desk any more. I use a stool, which is at one and a half times the height of a chair. It's a pretty standard size and stool, and has no back on it either. But they're kind of using all sides of the equation to their best benefit, right? Right?
