Super easy to put together - tools included. Comfortable. Arm height didn't fit me so I just left them off. If arms are important to you I might think about getting an adjustable arm chair.
I bought this chair on sale for my home office to go with my white desk. It was super easy to assemble and is extremely comfortable! It’s also lightweight enough to roll easily on carpet.
I find this chair not very comfortable for me. The chair back design does not permit sitting clear to the back of the seat cushion. The seat padding is not sufficient and will probably not last long term. I am average build 5' 10" 175 lbs
