Any office chair in similar price range would be at least somewhat better than a gaming chair. Gaming chairs are also overpriced so there really is no reason to but one unless you prefer looks (subjective) over comfort for done reason.
I was looking for some affordable refurbished ones like leap but it was either out of my price range or hard to find a good one. Ended up buying a cheap office chair, kinda regret it but ig you get what you pay for.
Documentation? For Nix? Yeah right.
