DANGER: Wood ladder rung SNAPPED while being climbed!

I was climbing the ladder to sing a bedtime song for my kid when the ladder rung snapped under my weight. I weigh 175lbs which is WAY under the rated capacity for this bed. I no longer trust the stability of the entire bed if the ladder so easily snapped under normal use. It certainly doesn't live up to the description's statement of "premium hardwood construction, perfect for kids, junior, teens, adults."

Note that it's already suspect that the Wayfair product listing says 400lb capacity, but one of the official Q&As says 275lb. It seems that Wayfair doesn't even know how much weight is safe for this bed.
