I bought this chair for my dad to replace his Bayside Furnishings Metrex IV Mesh Office Chair from Costco. At first, I was skeptical if a chair was really worth $600+, but I decided to give it a try. Although the delivery service could be better at providing me with a more accurate timeline, once the chair arrived, I was able to try it out for the first time. My first response to this chair was phenomenal, and it really made a big difference. There were no gaps from my back to the chair, which provided strong support. The chair is wide enough to sit however you like, has firm seating, options to control how far you want the back part to go, and a couple more that I am too lazy to list. My dad also loved it and had a similar reaction. So if you are looking to upgrade from a $100-$200 chair and want to enter the midrange budget range without being too expensive, I think this chair would be perfect for you. It is worth the investment, and your future will thank you.
**For reference, I am 5'8" and my dad is 5'4". Chair might not have enough space to Criss cross for 5'10+
