Took about 1 hour to put together. Instructions were simple and clear. Once the frame and back were put on, it was very sturdy. The only thing I needed a second person for was putting in the shelves. It looks nice and is perfect for my 2 1/2 car garage. It was a simple process. The bottom has a leveling function that was really appreciated when it was all done. Wish I had 2 of these.
