Love your blog & read it regularly. I actually own that shelf except I use mine for recipe books in the kitchen. They're the conceal shelf by Umbra. You can find them at the Container Store: http://www.containerstore.com/shop/shelving/shopbyAreaoftheHome/bedroom?Ntt=wall+shelf&productId=10016053Enjoy!
You can also buy it directly from the Umbra websitehttp://www.umbra.com/ustore/product/330638/c560/conceal_book_shelf.html
Live the life you dream about...I dare you.
