A floor lamp is long, top-heavy, and made of parts that come apart, which is exactly why it should be disassembled rather than moved whole. Left assembled, the thin pole bends and the shade crushes. Breaking it into pole, shade, bulb, and base makes each piece easy to pad and pack flat and safe.
Pro tip: Bag the small connectors and finials with the pole so reassembly is quick.
Watch out: Do not move a floor lamp assembled. The thin pole bends and the shade crushes easily.
