I wanted something that would fit into a corner and provide light, without hanging out into the room.  Also, it was going to go behind a chair, so it couldn't be so low or so round that it'd interfere with someone sitting down.  Perfect lamp; I waited months for it to come back in stock.  It was a bit of a pain to thread the excess electrical wire through the tubes (about 4") but it worked in the end and I'm happy with it.  I was worried the posts would not be straight or even with each other.  They appear to be and they don't seem to need anything up top to support them or hold them equidistant.
