@Somarasu honestly a better use of a "gaming chair" than actually trying to use one at a desk.
@Somarasu I got one secondhand for free once. They are designed to be pretty to look at, and basically be an advert for themselves via a distinct look and a prominent logo. So you see streamers with them because it is given for free or at discount to be an advertisement in the stream setup whenever they stand up.
They aren't actually comfortable or easy to use compared to a normal desk chair from an office store though. If anything, they are often really uncomfortable, and have issues fitting under desks, because of the weird gimmick shapes and armrests. They exist more to stand out than to be practical.
@Somarasu It would totally make a good balcony or patio chair if you have a place to roll it. Hitting a bong in one might be pretty fun, because then you could spin around since you won't hit a desk or something.
