At VMI the beds are called "racks." They are all wood with legs that fold out. (Think a piece of plywood in the middle supported by 2x4's) The mattress is the same as you find in enlisted berthing on a ship. Every morning your roll your mattress up and stack it against a wall with your roommates' and the racks fold up and stack against a wall also. The rooms vary in size. My rat year I had 5 guys in my room, but it was a huge room, and turned out to be alot of fun that year. The rest of my time there I had a slightly smaller room and there were 4 of us. There are a few 3 man rooms and if enough people from your class leave/get kicked out, you might end up in a room with only 2 guys, but that is very rare.
The daily schedule changes depending on the week, whether its a weekend, etc. But here was a typical weekday when I was there.
0500 Rats get woken up for PT, workouts, punishment, training etc.
0700 Reville, the entire Corps forms up in front of Barracks and marches down to breakfast. All racks must be up before formation. Rats get worked out/punished/trained after chow.
0800-1200 Classes. Typically there are 4 class periods during this time. If a rat happens to not have a class and is seen in barracks he can be stopped, quizzed on Rat Bible knowledge and worked out/punished until his next class.
1200-1300 Lunch time. Sometimes they make Rats, and Thirds form up and march down. After eating, this is a "fun" workout time for rats. This is when the upperclass can put their racks back down.
1300-1600 Afternoon classes. Typically labs and ROTC.
1600-1800 For the corps, its PT time. There are requirements on what workouts you can do in this time. Or you can play a sport, intramural, join a club, etc. Rats have more workout/punishment/training time and "Rat Challenge" where they do "teambuilding" exercises and workouts. If its a Friday all of this is replaced by a military parade.
1800-1900 Dinner formation for the entire corps, with a marchdown to the chowhall. After eating the rats are again worked out/punished/trained.
1900-2245 Study time. You are supposed to either be in your room, or an academic building studying. Obviously this doesnt always happen, but you arent allowed to leave post.
2245-2300 CQRB A designated workout/punishment time for rats. Barracks turns into chaos during this time. This is when rats can finally put their racks back down.
2300 Taps, all Cadets must be in their rooms at this time. From 2300-0500 you must be in your room unless you are signed out for late study in an academic building.
That is the basic schedule. Weekends hold more parades, football games, more fun for the rats, etc. Tuesdays and Thursdays, you have fewer classes in the morning, but you throw in a mandatory corps formation where you go listen to a speaker for an hour, do a parade, etc. Sundays are quiet days. No morning or lunch formations, you may leave post to go to Church. There is a dinner formation, study time, CQRB and Taps.
