Unpacking, this product is already very well protected, paper lined with a thin layer of foam protects all elements individually. No problem during assembly, it is necessary (as many product assembly), close all screws one after the other and finish the installation by tightening them. Good product and solid before this apparent solidity, I wanted tested by sitting on one of the shelves, well it held ... I think the wheels would be welcome ... I recommend this product without reservation.
