I had bought this chair for my husband for his work bench. When I started working from home, my office was making my knees and back hurt. Sitting for so long is hard on my body. I borrowed his chair and, wow, what a difference. I had to buy one for myself. It allows you to stretch & lean back, rest your legs on or behind the foot rest and lean on the arm rests. It is adjustable in several places. As a wiggle worm, I love this chair!
