Great desk.  Going to be using in my art studio, we are just waiting for the new floor to be installed.  It took about 2 hours for my husband to assemble.   He lines up all the parts in a line in order of their numbers.  Then he lines up the hardware in order of their numbers or letters, keeping them in their sealed bags. When you are following the directions, make sure you look at the pictures to be sure you have the parts in the same direction as the picture shows.  And the quickest way to assemble is to take your time and double check that the holes line up in the same orientation as the pictures.
