Read through the entire instructions booklet and get an understanding of each step for yourself before doing each step. There was missing information and a piece that was not indicated which direction to face in the instructions and didn't catch it until it was too late at the end when we needed to mount the base to the bottom. We made it work and hoped for the best but were afraid to loosen all the screws and take it apart again due to cheap material cracking and fear of the threads striping if we went backwards.
