Only con is that one of the predrilled holes on the board don’t line up with the holes on the ladder. The rest line up so it shouldn’t be a problem.
Edit: I have not used the wallmount cause I dont own a drill and couldnt be bothered, just leaned it against the wall and and the footboard of my bed keeps it from sliding down. I put my laundry basket on the shelf which is a bit too big an bulky for the shelf but does the job fairly well. The rungs I use to hold blankets I crochet and have put a long board the back and with all that seems fairly sturdy.
