This lamp is exactly what I wanted and the price was unbelievable.  I have been looking at this type of lamp for awhile now and some are 2-3 times more.  The base is heavy marble and very substantial so you don't have to worry about it tipping, so as some other reviewers noted, make sure you set it in place before assembling the rest.  Assembly was super easy, was done in less than 5 minutes.  Would definitely recommend this product.
