Assembly was a little complex the holes underneath the seat should be aligned better. But after that the chair is amazing sturdy and very comfortable. It's perfect for a taller (5'9 and up) person and so far so good. The chair is definitely top quality.
It was easy to assemble except for trying to get the wheels in. Wear leather gloves! I got my finger pinched so hard it rippd the skin open. Sits well for sitting in front of computer all day.
It's reasonable priced reasonably comfortable reasonably sturdy. I don't give it five stars because it's not the greatest but it's very good in every way. I guess it deserves five stars as an "essential" basic chair.
