74 screws. Oh, and that was just of one type! There are plenty of other pieces as the pieces of this desk are more numerous than my previous Lego collection. Just finding the instruction manual.. Er, novel, was like a sadistic Easter egg hunt. A few pieces came damaged, so this half-completed monster say like a war zone in my loft for a few days, but the end product was exactly what I wanted. My husband would probably give it 3 stars for the mental anguish involved in assembly, but it's a desk we can live with for a long time (now that it's in one piece). I think the quality is good, as it doesn't wobble and the desk tops are thick and sturdy... It's just a project. The desk came in two, hundred-pound, boxes so be prepared.
