I had been searching for a very long time for a floor lamp that used a three way bulb.  As I aged, light while reading has become more important and a 60 watt bulb just didn't do it any longer and 100 watt for ambient lighting was too harsh.  The base, moveable arm and shade are perfect!  I bought three for our family room - my husband liked it so well, he commandeered one for his office!
