Another set of furniture that does not require screws or nails is this line by Benjamin Vermeulen called Magnetic Assisted Geometry.  As the name suggests, the components of the furniture are held together using powerful magnets.  While some pieces look a little stark and utilitarian, but it is a good idea overall and the metal parts of the furniture are warmed by the wood.   With no screws or other tools required, the furniture is easy to assemble and disassemble.
