The last chair I bought was from Office Depot in 2017 and it's still going strong. Mine is mesh backed. Jay has a similar chair as well.
They were, in my opinion, very expensive BUT because of my chronic back issues, it was a must for me. My chair was actually marked with an incorrect price. At that time, the chair was supposed to be $399.99 (it's now $749.99!) but the paper tag said it was $279.91. Office Depot honored the price, so with taxes I paid $300. So I've been using it for five years. That's $60 a year, which is a very reasonable price for a chair I sit in very frequently with designing AND scrapping. My chair is still very comfortable and I'm having no issues with it, and highly recommend it.
Jay's purchase was an anniversary gift in 2018. He was going to get a standing desk. When he went to get the desk, the bin was mislabeled at $199.99 and the actual price was $499.99. They honored that lower price, so he decided to get a better chair. His chair was $399.99 (now $629.99!), but they had a sale, so he actually paid $260.00 for his chair. He ended up paying less for the desk and the chair than the desk alone would have cost. He was so pleased! LOL
I can't say enough about investing in a really good chair, especially if you are married to a desk with a desktop and two monitors (which is what I have as well). I also have a little footstool under my desk. I picked it up at an estate sale and it really helps to be able to put my feet up occasionally.
Here's the chairs in our den/office. I've also linked the photos below if you are interested in purchasing. Although I will say, it's incredible at the price increases just over the past few months.
