Have to table top lamps on the other end of the living room but the side with my chair near the bookcase needed a reading lamp and another light source.  This was the perfect solution and I am very happy with it.  I did have to have some help with the bottom section as others had mentioned since the threads were a problem to line up myself, but once it was done, it's a very nice lamp and I love just using the reader when I'm alone in the room.
