Upon getting the chair, the assembly process was very simple. From my perspective, there is no cause for complaint. The initial days, weeks, and months were highly satisfactory. This chair surpasses all other (office) chairs in terms of comfort, based on my own experience.

Replaced the pivot mechanism again, due to extreme use. Fit like a glove, and fits on older chair models too!

It's been around a month since I've purchased this chair, and it's both extremely comfortable as well as ergonomic. My back used to have a lot of pain from sitting and playing a lot of games, my old chair had no support for my neck or my lower back. If you find yourself sitting for more than 2 hours at a time to play games I would recommend DX racer chairs in a heartbeat.
