Decreases lumbar tension, improves mid and upper back muscles.
This stool is very comfortable, as I was hoping. There is ample padding in the seat, so you won't become fatigued after long sitting sessions, such as at your computer. The lumbar muscles take a break, and the mid and upper back muscles seem to automatically take over, and improve your posture, as well as &#34;working out&#34; the mid/upper muscles. Good buy!
