The hardest thing to do is put that back corner piece in. Once you've attached it, it makes the desk hard to move (on carpet in my case), but you can't attach it once the desk is moved into a corner because it attaches from underneath. This desk looks great, but it is an undertaking to put together. The amount of panels and hardware is intimidating. It's not hard to do and the directions are fine, but it's a lengthy endeavor.
