Great lampHEATHERGreat desk lamp. Comes with everything you need but the bulb. Priced very well . The only thing I miss (basing this on my previous purchases of this lamp) is the on off switch being on the top of the lamp ( now it is a switch on the cord) Thank you for keeping things affordable Ikea !3
Tertial LampKarenIt's a great lamp! So easy to put together and install. It uses regular household lightbulbs.5
Still a great work lightKieran E.Bought this to replace an earlier version from 8+ years ago. The articulation is great and the springs hold it in place well. After a few years it will lose some tension and begin to sag.5
Great valueJEFFDoes the job, very affordable, what’s to complain?5
Used with drafting deskLorraineWe have only had the lamp for a short time about a week or two. So far, the lamp works well, was easy to set up and looks good. We purchased for my son to use on his art/drafting style desk, where the desk has a slanted top. I am assuming that due to this slant of the desk the lamp can only lean to the one front forward position and will not stay if moved from side to side. It always returns to the forward front. This does not bother my son at all, he still loves it. I don’t think he realizes it should stay when moved. I just wanted to add, after reading some of the previous reviews I was a little worried about the on/off switch being on the cord. However, since the switch it is very close to the base it has not been a problem at all and is easy and convenient to use.4

What is steel?

Steel has unique characteristics when it is stretched and shaped since it remains strong. It provides strength to everything from skyscrapers and cars to bed frames and outdoor furniture. The steel industry is moving in the direction of more energy-efficient production and stronger steel qualities. It doesn’t lose any of its properties when recycled and today steel is one of the most recycled materials in the world.
