Not easiest item to assemble, you need lots of space and the small bits on the diagram, the important bits aren't at all clear. I dismantled the adjustable lamp head as per instructions to fit the bulb, only to find the bulb already fitted. This took ages to do as the screws in the retaining turnbuckles were so tight that I thought I might damage the lamp trying to unscrew them. Now it's assembled  it looks great but I would definitely not want to do it again.
