You're most likely going to consume snacks and beverages while sitting on that chair. Which one do you think would be easier to keep clean? There's chemicals to protect the upholstery but will they work on fur? I have my doubts...
Chewing gum, chocolate, greasy crumbs of chips, sticky sugar from a spilled coke... Not to mention sweat.
I've had a fabric coated gaming chair for some five years now and can't see any marks of wear. The spec sheet told that it had undergone some standardized wear testing which I gladly believe. Hoovering every now and then is all it needs, only once I've used some upholstery foam cleaner on the seat.
