Chair recommendations

Hey everyone, I just took my first remote job. Seeing as how I’m going to be spending a lot more time at home, and a lot of time on the computer, I need a good chair. For reference, I have EDS, and I struggle a lot with neck, back, and knee pain as is. I don’t mind spending a lot, (upwards of $300 or more if I need to), I just really want to make sure I get something that is going to be comfortable to sit in for hours on end. Please drop your recommendations in the comments, as well as any other tips of recommendations you have. Thank you!
