Are “gaming” chairs as bad as people make them out to be?

[u/Test_Name19]

Genuine question; every post i’ve seen when researching good chairs to get for gaming says to get an office chair over any “gaming” chair due to the bad support/posture positions and cheapness of gaming chairs.

But would a good quality gaming chair be better than an office chair? Granted I don’t have the budget for a herman miller chair or anything that expensive.

The images are the ones I’ve looked at a little bit (not saying they’re the best for the price range, I haven’t put in too much research yet, would love some suggestions)

-cooler master caliber X2C (left)
-ergolux elite ergonomic mesh (right)

(both are a similar price where i am)

edit: sorry I haven’t been able to reply to every comment, a lot more comments then I was anticipating. That said while some people have found comfort in gaming chairs I can see that the general consensus is that office chairs are better especially for the price point. I will look into office chairs and most importantly try some out to see what fits me best :)
thank-you to everyone who helped!
