If you've ever lost an important gadget to that black hole colloquially referred to as a "couch," you know what this is for -- it's a seat designed to hold your possessions without swallowing them whole. Designed by Daisuke Motogi Architecture of Tokyo, Japan, "Lost in Sofa" is made of upholstered cubes that naturally form slots. Sadly, the armchair's not for sale as far as we can tell, but rather one of a kind, and resided at DesignTide Tokyo 2010 until a few days ago. Ah well. Perhaps if we can find a vendor of plushy cubes, we'll just build one ourselves.
