Colo. My first year of college I was so worried about forgetting something. I was surprised that I brought plenty, and between my roommate and me we had everything we needed. We were smart to call each other before and decide who was bringing what. This is a relative question because the amount is nearly endless, but some desire more than others.
Every room comes with some sort of desk, dresser, and bed for each person.
Depending on how much room you need, lofting your beds might be a necessity. Remember, your room is your home for nine months. There are even those few who decide to turn their rooms into entertainment capitals in order to listen to their music and play video games all night. You really can fit almost anything into your dorm room. You can fit couches, recliners, entertainment centers, trunks, lofts, etc.
