As others have noted, the two boxes are very heavy and assistance is needed to move them.  Assemble it in the place it will occupy.  Amazing that only two boxes were needed; but note that the parts you'll need for one step may be in both boxes.  I ended up carefully unpacking both and then arranging the parts I'd need step-by-step.  Since the desk can be configured more than one way, read through the directions first so you won't accidentally start the wrong step when you get to that stage.  Took about 8 hours to assemble.
