Easy to assemble tool is included in the box. It’s a good quality. The issue of the chair is somewhat when I sit on - it slipping off. Good for petite person not wide enough. Best way to go to the store and see and try it for yourself.
I ordered this chair for my home office. It has great adjustments for height armrests lumbar etc. which is wonderful. The downside is the wheels don't roll smoothly or well at all and the seat is not very well cushioned. It is ok for sitting for short periods of time but not all day.
