This chair was easy to assemble. I did not a hammer to make sure all of the wheels were fully seated. The chair's adjustments are sufficient and I find the chair fairly comfortable.
I was very impressed with the packaging and ease of assembly. It took some effort to secure the casters into the holes. Otherwise the assembly was manageable. It is very comfortable as I have back and neck issues I want to correct. This chair will help proper posture when I work from home. Also the price was great with the sale which makes this quality chair an excellent value.
Have 2 of these that I purchased recently. Comfortable ergonomic and easy to assemble. Some people spend a lot of money on Herman Miller but these are just as good.
