Given the space constraints of a typical dorm room, the bed usually has many roles, from coffee table to easy chair. This is why functional yet stylish bedding is important. Bedding should be durable and be a color that hides stains and dirt. Since it is the first thing that guests will see, however, bedding should also reflect your personality, whether it is flamboyant, subdued or somewhere in between.
Video game systems are pretty much ubiquitous in dorm rooms, especially with males. However, the more your console can do, the more fun it is for everyone. For example, some consoles have a drive allows you to not only play the newest games, but also watch DVD's and stream music for all to enjoy.
The disco ball in a dorm room is borderline cliche, right along with strobe and black lights. However, it can be a great, yet cheap way to put an interesting spin on entertaining. A disco ball is timeless in that it tends to be a staple of multiple pop culture trends and its popularity spans decades. Plus, as long as the regular lights are on and the spotlight is off, it will not prove to be much of a distraction during regular hours.
Obviously, most dorms will forbid traditional pets such as cats and dogs, but consider smaller, more unique varieties. For example, iguanas, geckos, hamsters or fish are all relatively low maintenance, non-dangerous ways to spice up a room. Check the residence life department fine print to ensure what you are or are not allowed to have, then head to your pet store to see what is available.
