Tracking from Fed Ex was awful! The pieces for the desk were numbered and the directions were written according to the steps with the numbered pieces. A breeze to understand and follow.  First half of instruction book is for the L shaped desk. Second half of instruction book (steps 34 to step 63) is for the long straight desk.  Confusing to me was every page said do not tighten screws yet but yet I didn't see anywhere that it said to go ahead and tighten the screws. I did anyway.  I love the desk, it is a sturdy metal and heavy nice wood desk.  The file drawer is a nice smooth sliding drawer and will hold two sizes of files.  I love this desk!
