This chair has greatly upgraded my home office.
Assembly took only about 20 minutes with clear assembly directions printed in multiple languages.  The metal rod that supports the chair is super heavy duty. The casters I noticed were super high quality. The manufacturer included extra hardware just in case, which is always appreciated. I was excited to get it assembled and try it out. The lumbar support is excellent, the armrests are the right height to fit under my desk, and it is lightweight enough that I can move it around the house if necessary or move it out of the way to store it. The seat of the chair is a charcoal gray and the armrest and trim is a light gray which is very stylish. It has a modern look with looking comfortable. The seat has adjustable height, and it reclines. The casters roll really well on hardwood and carpet.Overall though, it's very comfortable, assembly was easy, and packaging was great.
