We only have one floor in our NYC apartment, but this basket caught our eye as something useful should you have a bit more space. We find the Ballard Designs catalog is always worth a flip through when it arrives, and this is one of our finds from this past weekend.
We like the fact that it will fit your stairs perfectly and looks like it's supposed to be there. It has a metal frame which means it's strong. Another great feature- a smaller organizer basket lifts right out for smaller items. Hey if the stuff's going to be there anyway, might as well give it a home. All of you people with two floors or more- does this look useful? It's $39.50 and available right here.
