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!
