Replying to Computer Chairs???

Hey everyone, I'm renting a house for this upcoming school year and I need a chair for sitting at my computer, doing homework, and all that other jazz.

I've been looking on Amazon but there are thousands of different chairs with a lot of mixed reviews.
What would ya'll suggest?
I'm just looking for a comfortable chair at a decent price, particularly under $100. Mesh, leather, I don't really care, I'm just not trying to break the bank.
Thanks.
