The instructions for putting in the base were not quite right, in my opinion. Also, the cabinet has the top and the upper shelf fixed with cam locks which make it sturdy at the top. The base, however, is fastened with screws and the other 3 shelves are adjustable. This makes the base unstable and prone the sides sagging. I would recommend cam locks for the base and one more shelf fastened to the sides, leaving just two adjustable shelves for more stability at the base. One of the hinges was also damaged and I have requested a replacement part online.
