Like a higher-tier version of the flatpacked Ikea furniture so many of us are used to building, the 3D Puzzle Furniture set from designer Elin Basander Lundin ships unassembled in a box measuring just 20" x 13" x 3". You won't need screws or Allen wrenches to assemble this table, chair and hanging wall shelf, however: As its name suggests, the all-wood set snaps together like pieces in a giant 3D puzzle and easily disassembles back into the box for storage (or eBay shipment) once the kids have outgrown it.
$360 from Zwello, and it's also available in white.
