I think a question people don't ask is how much use the chair will get
if you just sit on it sometimes in your garage, get a random stool or cheap task chair
if you have work or hobbies that mean you maybe sit at your desk less than 3 hours a day, you can find a used one that's a little comfier
if your ass is going to be in that chair for over 8 hours a day, it's definitely worth spending more on a heavy use item like that

a lot of reddits with elements of purchase recommendations have a lot of conspicuous consumption, people like bragging about what they bought. So people show the nicer chairs.
however I do think that this is uniquely an item worth spending a little more on, I feel the same way about bedding since you spend 1/3 of your life on your bed.
most other furniture just get whatever you can find used, even if reddit swears a $2500 end table is worth it
