I bought this chair because I wanted something that would be comfortable and adjustable. Still working on adjustments but I am happy with the purchase. It took two of us to put it together (one holding pieces in place the other screwing them together) and adjustments also take two--one to sit and the other to move the adjustment knobs.
This chair was SO big I couldn’t fit it in my desk. Then when I drove back to Staples to return it the chair kept hitting me in the head in the car. There was one hot dude working at the store when I carried it in to return it so I got anxiety. The chair was really soft and comfortable. :-)
