My daughter has had both bunked (one room quad, two bunkbeds) and a lofted bed over desk in a double. She has had it with making her bed in the stratosphere, head close to the ceiling, and climbing to get in and out of bed. With the bunk bed she wanted the top so visitors or roommates wouldn’t sit on her bed, and she and the girl on the bottom bunk had to split the underbed storage space. With the lofted bed she had a huge desk, but less underbed storage space. Thankfully both had rails as are required at her school. She’s happy to be moving to a regular dorm bed this coming school year.
