Comfy chair for guests (Northeastern University)

Hello everyone. I would be honored to take an extra chair that any of you may have. I moved to a studio in Boston three months ago and am still working on finishing it. I live off the Northeastern University train station. So ideally I need something that I can carry on my own and take on the train back to my place. I would be forever greatful if you could help. I am not looking for a kitchen table chair. Something a bit more comfy for any guest that hangs out with me here. Thank you. :)
