I have seen several over 100 years old wardrobes that can be disassembled and reassembled in minutes without damage because they are held together by metal fittings that hook into each other. Like the better Ikea stuff, but much sturdier, especially the actual metal fittings. The wardrobe I remember best had three doors - it would barely fit through any door if it couldn't be disassembled for transport. It had a socket part, separate wall parts with aforementioned fittings, and a top part that could be slotted onto the walls (and doors with their simple stick and hole type hinges) after assembling them. Assembly and disassembly was as simple as it sounds, if not simpler.
