It's a good chair. It works. You can sit in it. Your back won’t turn to mush. It doesn’t cost a lot of $$$. If you have wood floors buy a small carpet to put under the chair because it will scratch your floors up over time (the wheels are very hard plastic).
Super comfy.... easy assembly. Can't beat it for the price. Only negative (for me) and I knew this going into the purchase is the arms don't adjust (other than slightly if you move screws). They rub against the underbelly of my desk. Again I know this going into it and it's still worth it.
