I don't know the weight exactly, but its not that much heavy, i can take it by my self easily, its just hard to manipulate because its huge (72inches by 30 inches). I just glued, screwed and added some dowels and i think i should be fine... the top is not fixed to legs yet and its very stable. It didnt move at all. The only thing i hope is adding 3 monitors will not made it bend in the middle, but i also added a 12 inches panel between legs to support this section and prevent it from bending. so i cross fingers!!
