I purchased this lamp to put behind  a curved sofa to be able to read.  The lamp takes a 3-way bulb. The rectangular lamp shade is just what I wanted to sit flush against the wall.  I would have preferred the lamp itself to be at least 2 inches taller than it is. The instructions were not very clear and could have used more words along with the photos. The photos did not clearly show the assembly  instructions of the various parts. We basically put it together by trial and error. 

Pros: Perfect for behind a sofa
Cons: Assembly instructions not clear
