Well, I wouldn't call the assembly "complex", but it certainly wasn't "quick".  A lot of steps for such a small item - but in the end, all the parts were there, all the holes lined up - and the final product is very sturdy and looks very nice.  I'd suggest you pay close attention to the exact measurements.  This is a very nice 2-drawer/2-shelf item - but it's compact - and the depth of the unit makes the drawers a bit "shallow".
