IKEA vs. fancy mesh office chairs, what's worth it?

It's terrible experience with office chair so far. I'm former football lineman with a large set of shoulders, i can’t just settle for something flimsy that wont support me properly. i saw some mesh chair in IKEA, the finish of them looks solid and i think it much cheaper, even faster than ordering from Steelcase, Autonomous or you say Herman Miller.

At just $200 and it totally look like Aeron or Leap V2. Is Herman really the only option worth buying for my home setup or are we just paying for its brAnd nAme?? tell me the $500 difference?
