I'm just wondering, I've had a sore back on and off for years due to laboring work that I did growing up, I'm just wondering if I should get rid of my old "gamer racer" chair and invest in a proper office chair? I don't really know much about ergonomics but I am wondering if you guys think it would be worth parting with the $60? my local supermarket just got in a bunch of these nice looking office chairs and they're the cheapest I've seen. Just wondering if that is a worthy investment for my health in the long term?
