Spot on. I used to have back pain and all sorts of discomfort throughout body, neck shoulders, etc. until I figured out how to properly sit. Luckily I haven't had any issues lately, I'm in my mid 40s and have been in a much better shape than I was in my mid 20s. I don't use a stool necessarily but I try not to use the back support too much and for me the sitting area must be rigid, any cushion can mess up with my sitting position.
