We had a heck of a time getting Angi to finish the assemble, but after 4 bookings it seems to be assembled properly. My wife could not have helped me with this, but if I had 1 or 2 strong people to help, I could have followed the instructions and assembled myself. The top shelf needs to be held up and connected with screws to the tall shelves on each side. That is where the extra helper(s) come in. It took Angi assemblers almost 10 man hours to assemble. If you pay for Angi assembly, request 2 people or be prepared to help hold up the top piece when it comes time to connect to the side tower shelves.
