All parts had a number or letter and instructions. There was even small tools included. It was harder to put the main desk part on as screws had to go up and line withthe holes... so i gave 4 of 5 stars. Also the top piece sticks out from the back making the total depth dimentions more then I was expecting. So that bumped it downto a 3 because i was looking for a small space desk at a maximum certian depth and was not expecting the extra depth out the back from the measurements.  Also the main desk table is wider then the dimentions of the feet dimentions as shown... just note the top hutch part sticks out even more from the back.
