Stylish floor lamps..  

Floor lamps are easy.
It's table lamps that are hard.
I've said this before, but to find the ugliest objects in the world, just search Ebay for "table lamp" and sort highest-price first:

There are LOTS of good-looking floor lamps, though -- so many that just asking for unconstrained suggestions might be no more helpful than doing a Google Image search for "floor lamp".
Do you have any preferences already? If you can narrow the choices down, you'll get better advice. Take a look at the "Show your lamps" thread linked below; there are plenty of styles represented there. Do any of them particularly appeal to you?
