Instructions for assembly were slightly annoying as pieces don't have a label for which way is up (like the drawer for example).  There is a gap between the top of the drawer and the desk no matter which way you flip it.  There are not enough screw caps so we just did not cover the back since that will not be visible in our home, however we did not count the number of screws ahead of time and had to remove caps to move them to the front.
