We also love these, ahem, cardboard boxes. Not exactly unheard of, but definitely a contender for modern looking nursery storage.
Another one of our favorites is this chest/bench piece. Two children can sit together and enjoy a good book and the belly can hold a special blanket or toy.
For the finishing touch, add a couple of these simple cardboard frames. Like the Lullaby Cradle, these Green Lullaby items ship flat-packed and are assembled without tools. When you're done or if you need to make room, you can disassemble and store them away, or recycle the cardboard. For retail and price information email them.
