I purchased this gaming chair to replace my old and worn out office chair. Assembly was straight forward and went as other office chair assemblies go. Everything was packaged very well and the hardware package was complete. A 5 mm Allen wrench is included with the hardware but I used my own tools to make the assembly easier. Overall the chair is comfortable being that the padding is new and everything is tight. Time will tell how long it lasts. I seem to go through a chair every five years or so. The reason I didn’t rate it five stars is because the chair has a slight lean to the right that is noticeable when you sit in it but every chair that I tried in the store seemed to have a similar tilt. You can actually see the tilt if you look at the back of the chair from behind it. Maybe this is common with the design of these chairs. It was half the price of the former chair I had so if I get the same number of years out of it I’ll be happy.
