The lamp is very nice and appears to be quite sturdy.  Everything went together tightly except the post that attaches to the base.  It seemed to tighten and then loosen again when I tried to tighten it.  I am not the strongest person and surprised that it didn't let me tighten it completely where the post would not move.  It does seem to be tighten enough so as not to be a problem and it won't be moved around so should be okay.    Nice lamp for the price.  Provides nice amount of light for my sewing and a good price.
