Amaaazing chair. My mom borrowed it for a couple days and said it was so comfortable that she bought her own in purple! The only issue is that you can't kneel on it because you can feel the pole through the seat. When you're sitting on it how you're supposed to, you can't feel it at all and it's like sitting on a cloud. The lumbar support is amazing for my back, it slides right under my desk when the arms are up, and the rocking feature lets me fidget around and move how I like to. It's perfect!
