Just received this unit. I always count myself handy, but this unit took 2 person 3 hours to put them together. The sketch is straightforward, but we spend the most of the time to adjust the positions of parts, otherwise, they won't fit together. our final product is not perfect, there are still gaps between some parts, but we don't spend any more hours. 
Also, the pieces are made of some cheap paper board.  paint is off on some corners.  the is one screw that is not deep enough to put screw in. 
Stay away from this product!
