Posted under sofa futon

I’m a college students so I need furniture for my apartment. I really don’t have the money for expensive furniture so I’m looking for a futon or sofa bed that is under $250. I need if as a couch and also if any of my friends stay over the night. So i want to know which one is more comfortable and likely to remain comfortable longer.
