It took several hours to assemble. I had to study the pictures first to make sure I understand since there is no written directions. Steps 1 and 7 need  a second person to hold one side to keep it stable. Part D is a very thin and cheap manufactured wood. After I attached it to Part A and while attaching Part B, it slipped and the hole with wood dowel attached to Part A broke open. I had to run to Lowe’s for wood glue! Hardware #12 (L key) was missing from the box. I got one from Lowe’s also. Because of these, I’m giving it 3 stars only!
