The assembly isn't hard at all, and the directions are easy to understand and follow in order; however, it does take time to assemble but considering its a corner desk with lots of pieces thats to be expected.  I use the desk with two computers, one with a dual monitor display and the other with a 26" display, and all this fits comfortably and spacious on this desk.  Once you get the desk in place, its hard to move.  I was pleasantly surprised at the durable/sturdy and quality construction of the pieces for the price.  I'd recommend this desk time and time again.  Once I get more space for my full size LAN work area, I will purchase another of these desks and join them together.  Its easy to modify the instructions to change the layout of the desk.
