I've Been Up All Night Thinking

I am stuck at the crossroads where I really am trying to figure out what is a want or what is a need. I believe it is time for me to buy a new office chair because my old one which is 6 years old is no longer able to keep me comfortable. It has wear (a lot) because I use it daily for at least 3 hours a day every day of the week for work. But my big issue is that I am attempting to look for a replacement but the prices are hitting me hard. The one I want is $160-$200 and it is very comfortable and upholstered with leather. What would you do? Would you get the new office chair or keep using the old one until it breaks?
