Hi,
As a full time gamer and champ in gaming, I also suffered from a lot of health problems. I used to sit on the chair for 10 to 12 hours continuously. As my interest was increasing, so did my health problems.
I have used at least 4 gaming chairs in my experience. Fortunately, I have one myself that helps me to reduce buttock pain. This chair is comfortable, made from a strong material, long-lasting, and it can bend around to stretch your body if you feel tired while playing games. .
The most amazing thing about it is that it is under 150 dollars and is comfortable.
You should make sure that your gaming chair must have a cushion for comfort sitting and retractable footrest as well.
I am using GTRACING Pro Series GT099 since 1 year. This gaming chair is the best chair from every angle and for the enthusiast gamer that is on the rise.
