Some might think having your own coffin in your house is morbid, but not William Warren. In fact, the furniture and product designer created Shelves for Life, a build-it-yourself Ikea style bookcase that, after you’ve expired, can be reassembled into a coffin. Not only is it good for the environment, it’ll be one less thing your family has to worry about when dealing with your remains. The kits sell for $579 (or 350 GBP) a piece and come stained in a classic blonde wood which just begs for some serious customization. Creepy and awesome.
