Just by the way $350 is not even close to expensive when it comes to office chairs. Check out Herman Miller chairs (which I believe currently sell the most expensive office chair) or companies like Steelcase to find out what a truly expensive chair costs. Some people actually buy these types of chairs for home and its not just rich companies. I guess if you're sitting in it a lot at work or even if you are a student studying it all the time it could be worth it (although students probably can't afford fancy chairs), just like if you type a lot a mechanical keyboard is a good investment if only for comfort reasons and not performance.
