I just got this chair and put it together pretty easily just as the instructions described. Only problem is on the bottom of the chair one of the screw holes appears to be off the grid when compared to the others therefore that screw goes in sideways and doesn't allow for a good amount of tightening. The chair seems stable enough but sitting in it it squeaks! Not sure I can recommend this not even sure if I'll keep it.
It was on sale easy to assemble comfortable. I use it for my office and not "gaming" but I think the idea is that you sit on it for a looooong time. But so far (two weeks) it's doing okay.
