Hi, I'm leaving a comment in case anyone might be interested. I bought a gaming chair recently but this guide I found online to buy the best gaming chair helped me to make the decision and today I am very happy with it.
I can recommend Killabee gaming chair, also got it recently and it's a really comfortable one. I pass a lot of time at the computer, and my back hurts after a while, but when I decided to took that chair after reading some reviews, my back pain has gone! I would not believe at first, but gaming chairs are really the best! Give a look here, I used their reviews before purchasing my one.
I would recommend you merax gaming chair as it is quite comfortable and supportive to the body. I had also bought a computer chair for myself recently. I started having pain in my body and that made me think of buying a new comfortable chair. Luckily I found the chair of my choice here and then I ordered it from Amazon.
