The issue is that this, as @TheSteelyardDweller pointed out, is that it's not just people who sell Gaming chairs that go about marketing like this- it's most other gaming products, and it extends even past gaming. Marketing ploys such as this are prevalent in daily life- companies claim their product is the best or it does this or that when in reality that product isn't the best investment of your money. It's become so ingrained in society, that much as I appreciate you pointing this out and trying to make others aware of it, nothing's really going to change in the near future.
