First off the bat, the box is extremely heavy so get a friend to help lift it.  Lots of pieces but the instructions and itemized hardware packets make installation a breeze. You will need a small hammer to install the trim pieces. Caution, when making the drawers they use a plastic bracket to fasten the face of the drawer to the inner box. Careful not to over-tighten screws as it can crack/break the plastic bracket. My opinion is this piece should be made out of metal, I might find a metal bracket in the future to replace for extra rigidity. Great piece, would have got 5 stars if it weren't for the plastic inner bracket.
