You could make doors to go over bookcases or use a horizontal drawer file cabinet. The one I have is 3'wide, 4'high, 2'deep that's 4 drawers. Easy to use and can handle alot of weight. looking for a pic to show.....PLEASE excuse the mess we are still remodeling the house and my room is on the bottom of the list.
You can only see the top drawer on the right side of this photo
