5x10 storage units are a great solution for a wide range of short-term and long-term self storage needs, including moving to a new home, storing college dorm room items, using storage while deployed, and decluttering a house or apartment. These units are comparable in size to a walk-in closet. 5x10 units can typically hold the contents of a small bedroom or dorm room, such as a queen-size mattress set, dresser, TV, and several boxes.
