If you follow the directions carefully, laying things out in the same direction as the drawings and lookingfor L and R, which seem to be new indications they are putting in for their American market, you’ll do okay. That said, I was so faithfully following the directions that when I dropped the manual and picked it up and accidentally opened to an optional left-side orientation for a desk, I faithfully readapted and ended up with a cord channel on the front of the desk. That’s ok, I use it for a cup holder...because I sure wasn’t about to take it apart and reassemble.
That said, IKEA has the easiest assembly furniture ever, and the stuff is solid and lasts.
I like that story!
