The unit came in a compact box, well packed, with all parts present.  A helper while assembling was helpful but not necessary.  The adjustable shelves are a good feature.  It was necessary to look carefully at assembly instructions because construction starts upside down and it is easy (for me) to get confused.  One small glitch is that if you place a stereo component too far forward on the shelf (while wiring things up) it (the shelf) will tilt because the forward support peg is not far enough forward.  Also, if the back side were more open it would facilitate running & connecting wires.
