Weighs a ton, so very difficult to carry up the stairs by myself.  Weight is due to bottom piece which weighs down the top so it doesn't tip over.  The arms aren't as flexible as I would like.  I wanted to have some arms lower and some higher.  The whole piece is much larger than I imagined.  Assembly was fairly simple.  Lamp is just o.k.  Keeping because it does provide a lot of light, but it's a bit of a clunker.
