have money but idk where to spend

go buy something nice to eat and drink, after that go and invite in town a nice girl, it's more satisfiing then gaming :D

Depends on how much and what you like to do, I would buy a Creative 3 3d Printer for the sake of assisting my design skills so I can actually see if my designs are properly effective. Plus you can print all sorts of stuff, though I would not get it if you are not going to delve deep into a hobby or job that uses that kind of hardware.

Are the ergonomics of gaming chairs better than traditional office chairs such as Herman Miller? I understand the aesthetic appeal, but being comfortable should be the priority imo.

My advise is to invest to get more money so you could buy all of them.

Save your money, dont feel a need to spend if you have no reason too.

go for the chair
it is better playing comfort than getting a headset or a mouse
chair is nr1 for the gamers

Keep it for something really important I guess but idk I can't really judge

Pursue a hobby or something, as those things occasionally require large payments in order to get going.

When you dont have an good chair I would get one cause you can easily get back issues when you use a shitty chair.

Save the money, invest it, and then you can buy 100 gaming chairs in 5-10 years.
