1, Upper berth: Actually, the advantage of the upper berth is that it won't be disturbed during the rest, and the privacy of the upper berth will be better, and the upper berth is still very clean. If you are neat, you don't want your classmates to sit on your bed. Also, if you have something you like better than what your classmates touched, I suggest you put it on the upper bunk. No one will have to go back to your upper bunk to get it. Then, it's a good choice for you to choose the upper berth.

2. Lower berth: The biggest advantage of living in the lower berth is safety. Many students worry that they will fall off the bed when they sleep at night, or it is convenient to get up at night. I don't know if you have heard of it. Some students on the Internet said that climbing the bed ladder back and forth during the four-year university period was enough to climb Mount Everest. Therefore, the biggest advantage of the lower berth is that it is convenient to move below and has enough security when sleeping.
