What can use as a bed?

Hay lounge, I live alone in a 1 room apartment. Right now Im using an enflatable air bed to sleep on but its hueg like xbox and I want  it so that theres more space in my room. (i dont deflate it)

So what can I get as an alternative for a bed that is small enough to fit in my tiny room? It has to be comfortable, and easy to clean, and if possible something that you could put away when your done sleeping on it. I can spend about 100$ max. Any suggestions?

yeah, a foam mat or a sleeping bag.  if you have a mat, you don't even have to roll it up, you can just lean it standing against a wall.  (depending on how hard the foam is.)

i wanna live alone in a 1 room apartment :/

anonymous, how much are you paying for rent, just out of curiousity?
