My husband assembled and installed this unit and found it quite easy to do.  He found doing things a in a slightly different order than stated on the instructions helped and it did take the two of us to mark up the wall using the guides provided to fit it. Each piece of wood is numbered and this helped too. We just took our time and checked and double checked measurements and successfully installed it in our spare bedroom/office. The item came extremely well packaged and even though dented on the outside it was well protected on the inside. This item is heavy though.
