My teenage daughters love these ottomans. We moved and downsized their room from a full 2bedroom attic space to sharing one bedroom.  
They are able to store their books supplies and other Knicks knacks they have in them. 
I would show a full picture but I am still doing some decorating. 
I used them for a sitting area on one side of their room.  
It eliminates having to sit on their beds for leisure.
