Arrived today. Comes fully assembled except for the keyboard tray. Putting the screw caps into the holes in the keyboard tray required a hammer. Others may have strong enough hands to push them through, but not me. Once I figured out how to get the caps into the holes, assembly was quick and easy.
I gave it 4 stars instead of 5 because I also bought the Dual Monitor swivel stand (the more expensive one). Not thrilled with how it fits onto the desk converter. The mount that is under the desk converter interferes with the ability to lower the desk all the way. In addition, once the very heavy mount and two monitors are on top of the desk converter, I can't lift the thing from a lowered position anyway. Thus my desk converter is now really just a stand up desk. Which is ok-ish. Just not what I was expecting.
