A genius designer from the UK, William Warren, designed and made a bookshelf that could accompany people for a lifetime: Shelves For Life. Of course, this does not mean how good the quality of the bookshelf is, but rather its symbolism of being with people from birth to death: it's a bookshelf when you're born, and when you die, it can be disassembled and reassembled into a coffin... It's quite a darkly humorous work, haha.
