I love my A-dec stool because you sit on there and you forget that you are, you know, sitting for three hours. I sit pretty much eight hours in that stool. And then my body is not sore. I remember using different pieces of equipment in different offices and trying different stools and it wasn't comfortable and the A-dec stool makes it so ergonomic. And it's just, it's amazing how your body doesn't feel the pain of the dentistry because it's so comfortable.
