Each piece has full edges and the shelves only fit together one way most of the time so its super easy to assemble, all the holes are predrilled and the cam locks even have nuts set on the board, so they lock in nicely and smoothly this impressed me even more as I looked forward to fishing the wooden dowels out of the bag and coming back with the metal dowels to put the dividers in I shed Tears of gratitude, something I wouldnt have experienced No need to worry about breaking pins when aligning holes. It takes me maybe 10 minutes to assemble the shelf myself, super sturdy construction and simplified assembly parts. If my electric screwdriver had an Allen wrench head, it would be professional grade. The stand is sturdy and nice, and my daughter is delighted.
