"Gaming chairs"
I have to agree that gaming chairs are pure trash. PU bonded leather that breaks down over time, bad ergonomics, and so on, it's simply not worth the money for what you get.
I have a full-featured Aeron remastered that I purchased about a month after it was released, and it still looks brand new. My only complaint is that it sometimes causes my thighs to go numb after few hours of sitting, and going to a brick-and-mortar shop to get a feel beforehand will never give the end user an accurate representation of how comfortable it will be long-term. Moreover, I think if somebody is able to spend a few grand on a PC, then they're able to spend a decent amount on a quality task chair that will inevitably last a lifetime if cared for properly. Steelcase, Herman Miller, and Haworth are all amazing companies.
I went with the Aeron because it's iconic.
