Question: Does the swingarm function easily and does it stay level when extended? Thanks!
Document: Upon opening the item we noticed there was a scratch on the base plate. We went ahead and assembledthe lamp and we noticed that the swing arm was not level with the floor. There was not an adjustment that wecould make to correct that problem. One other thing was the lamp shade was too dark for the roomthat we were going to use the lamp. We asked for a return on the item.
after reading the reviews for this lamp i was fairly certain of what i would receive. they were easy to assemble and look good in the space i got them for. the family is enjoying the swivel arm feature.
While this lamp is beautiful it came to me with a flaw. I could not screw one of the sections together. To the company's credit the gave me a full refund with no hassles.
Too dark Shade  NOT as tall as appears  Provides little light  Room is brightly painted and almost makes appear dark
This lamp is OK - despite posting questions on the height of the base, it was still too high to fit under our couch so I ended up moving it some, which worked out. It seems a bit short for a floor lamp, and the light is rather dim. I'm going to try a CFL bulb next and see if that helps any....
They should post that the shade is color DARK GREEN.
The picture appears that the glass portion is clear glass, which is what I wanted. When it arrived the glass was a deep amber and does not go with my decor at all. The lamp itself was a nice style, liked the shade and was so disappointed that the glass was amber. What is up with that? Not one picture shows it other than clear!
The only reason I did not give it 5 stars is because the lamp is a little wobbly. The rubbed bronze looks very expensive. The glass is kind of amber-colored, so if amber isn't your thing, you might want to think twice.
The lamp is made of good quality. Nice and heavy. Won't tip over if you happen to brush against it. Looks great in my den.
My other floor lamp stop working on all three settings so I needed a new one. I was very skeptical about buying one online sight unseen but took a chance because everything I purchase from Amazon is usually so dependable,  I'm so glad I took a chance, this lamp is wonderful and is EXACTLY what I wanted.. I would highly recommend it....the packaging however required two people to extricate the lamp from the box...it was quite a challenge but well worth the effort.
Answer: no
