The unit is well packaged and all of the pieces are labeled with a number. This is mandatory with so many parts.The instructions are somewhat thin for most people. There are no written instructions.........just sketches. The sketches are accurate but you must take great care to understand front and rear before assembling. There is nothing to guide you regarding front and rear and you can easily assembly the top half facing the wrong direction with respect to the bottom half. Ask me how I know.The statements by others that the unit is flimsy are accurate. You only get stability after you get to nearly the end of the assembly process and install the final piece M to tie the two sides together. THEN it is stable and you can lift the entire unit and place it behind the toilet..........by one man. However, the stability is not present to keep it against the wall and you MUST install the provided wall anchors.Be sure to have a battery powered drill with a phillips bit to install the back panels. Otherwise be ready to see an orthopedist for another set of wrists.The hinges for the unit were designed by an idiot. This type of cabinet hinge is always provided with SLOTTED mounting holes. This unit has two slotted and two fixed holes. So, if you expect to adjust the hinge up or down with the slotted holes..........well........good luck with that. You get whatever position that the predrilled holes in the sides provide for you and THERE IS NO ADJUSTMENT. The manual lies to you with their instruction to adjust the vertical height.Sadly, we have a product that is sold by someone who knows nothing about it and has never assembled it themselves. Quite typical of these Amazon sellers today. Buyer beware.
