Extremely easy to assemble.  If I can do it, anybody can :)  The instructions were simple to follow; all the pieces were clearly labeled; and I was delighted to see I really didn't need any other tools other than the one included to assemble.  I did not pay enough attention to the width of the desk and realized that dimension is a little smaller than what I would have preferred.  It does not have a sliding keyboard tray beneath one of the desk tops, so I think it important to note that in addition to the width.  Still very please with the purchase.
