Chairs with built-in bookshelves. It seems like a concept that someone would have thought of a long time ago, but lately everyone is designing these multi-functional pieces. While examples like Nobody&Co's Bibliochaise leave much to be desired (I think it looks rather unkempt with the books resting at different levels), models like Nils Holger Moorman's Bookinist shine.
What's great about this chair is that in addition to being a functional piece, it has a fully developed concept with an interesting narrative. The Bookinist is the ultimate all-in-one reading rest spot. Designed like a pushcart, you can wheel your mobile library anywhere. It also comes complete with a side lamp and hidden compartments for reading glasses, pen and paper...and the all important cup holder.
