I absolutely love the under the bed storage idea pictured above. Even if you only have one child, they can use one bed for sleeping and the other can get some big pillows to prop against the wall and make it into a reading space.
I wanted to find some more great ideas for you guys and found an article over at Apartment Therapy that rounds up 10 additional ideas. I really like idea #7 that combines lots of shelf storage and doubles as a desktop for art/school time projects.
