The desk was time consuming to assemble, but not difficult.  I love the desk, but there is one MAJOR design flaw.  There is a wooden bar at the back of the desk (the higher one) that my knees bump up against when I sit down at the desk.  I am only 5'4", so it is not due to my height or leg length.  The desk does not seem suitable for average (or above average) height adults.
