The wheels need to be pushed in place with significant force. Otherwise very easy to assemble. Attaching the head rest is optional and it looks better but less comfortable if not attached. I think the arms would not adjust low enough for a short person but otherwise it has lots of adjustments.
We love this chair! It is so comfortable. I love that you can adjust the tension for your back and also adjust the tilt and arms as well. The chair went together really easy. Would definitely buy again.
It’s a great chair. The only thing I would have different is have the back lock into place instead of reclining when I lean back. There are times that reclining is needed but if I need to sit up straight the back provides little support or comfort.
