With a short seat it gives much better back support. My previous chair had a depth seat and did not support my back. The cushion is nice for now. Time will tell if I wear it out over the next few months.
The price was right. The screws holding the armrests to the seat and back do not hold well. They loosen up and the threads or inserts are stripped. If you try to tighten them they slip and loosen. Could be a safety hazard if they loosen all the way and the seat disengages from the back rest. The screws seem undersized for the load on the chair. I would be wary to recommend this for the safety aspects.
Not as nice as I hoped. The chair was simple to assemble. However it leans slightly to the right which is an annoyance. Also the seat cushion looked compressed after only one day of use.
