I can say that this definitely does not hold 36 pairs of our shoes because my family has large, wide feet. I already knew this prior to buying it, and it is very sturdy. I have had no problem with it coming off the door or falling apart, but I did screw all the sections down to the door with the hardware it comes with as shown in the diagram.  It is great and clears up space where our old shoe rack sat on the floor.
