Took at least 4 hours to just put the ladder together because the holes are off-center, which makes it impossible to screw the screws in right. And some screws are still not in all the way. Protruding screws are a hazard for my 3-year old, let alone a younger child. This is why I feel strongly about writing this review. It’s a matter of child safety. The manufacturer and resellers have to improve this product.
