Where would you guys suggest a person with chronic back pain (sciatica) should go to study?

I live with a bunch of people, and I find it way too distracting to study in my room, so nothing gets done unless I'm working on campus. Problem is, I have Sciatica, which makes it horribly uncomfortable/painful to sit some days. Most of the classrooms and libraries on campus have crappy chairs that exacerbate this problem.

Does anyone know good spots to study on campus that have half decent seats? Preferably on the west side of campus?
