Instructions to assemble were cumbersome with the two different options of assembly! Definitely not for a novice. I had  two of the same side pieces. I called the manufacturer who expeditiously sent the replacement side piece. After assembly I noticed the top edge of the desk had some shipping damage but decided to live with it since it’s already together. It take two people to move assembled pieces into is final installation and should be near its place of usage because it’s  heavy and awkward to move. It’s a great looking desk and I am satisfied. Not sure I would have ordered if I knew what was involved with the assembly.
