It works fine for us.  However, its quality is not anywhere equal to its price.  I'm not sure what the wooden posts are made of, but not walnut... We bought two of these lamps and in both cases the wood was stained to approximate walnut, but the stain wasn't absorbed evenly, it would fool no one, and the wooden elements lacked the rich grain, evenness, and texture of real walnut.  

And, at this price we it's really what we had expected.  

The shade is quite nice, and the light switch accommodates a 3-way incandescent bulb. (But who uses those anymore?).  Very quick and easy to assemble.  

We did keep one of the two Tripod Lamps that we purchased because the one does look good, in a mid-century modern sort-of-way.  But, our advice is to keep looking. We're guessing that you can do better at this price.  Over-Priced.
