The desk took us two days to put together.  The hardest part is the file cabinet - which takes Legal Size hanging folders.  The reason it took two days was because the boxes arrived damaged and the corners of the desks themselves were crushed.  The file cabinet was not damaged.  I notified Wayfair of this & took some pictures of the boxes and pieces.  Wayfair did not hesitate and sent out a whole new set to us.  We love our desks and use them daily.  Wayfair has been great to us!
