I am not sure how a "Gamer" wants to sit. I want to sit with good posture and keyboard and do for several hours at a time. I find as others have that the cushion is not as supportive as I would like. It felt great when I first bought it but seems to be losing it's resiliency quickly.
I just got around to building it last night. It was easy to do (all the instructions are in picture format) and took me less than an hour from unboxing to finishing. I'm sitting in it now and it is very comfortable. I like that the armrests can be completely raised to get out of the way when I push the chair toward the desk.
I bought this as a new all-around chair for my dorm room for studying at my desk playing games watching tv. I've used it for four days so far and all I can say is damn this is one comfortable chair! I love that the arms fold up so that I can get them out of my way occasionally. It reclines nicely not too much or little. I like the tall back it's very supportive. Overall great chair I'd definitely purchase again. I also purchased the warranty because I can be a little rough on my desk chairs we'll see if the chair holds up or if I'll have to use it. I'm hoping that the warranty works exactly like the girl in the store said it would where I log my complaint and they send me one without having to return the original.
