Ive had the chairs for a couple of weeks now they are comfortable but you definitely need that lumbar support cushion I am short so I cannot get the pillow to go low enough because the arms are in the way which is kind of annoying  The stuffing in the cushions are kind of weird also.When you twist the handles to put it in lock in a position you have to really tighten them down  tight or the chair back will move on you.
