The shelves are pilled high with books, pictures, and maps. If I'm in my room please knock and if I don't let you in don't feel offended. If you don't knock be perpared to die. I have been trained well by my dad.
Adjustable metal shelves (found at Walmart, Target, Lowes, Bed Bath & Beyond, etc.) are great for adding storage over a bed. Just adjust the shelves at the highest levels and you have created a great space to add boxes, books, plants, and picture frames.
