For some years as a fairly young kid, in between a crib and a real bed, I had a mattress on the floor.

When I was in college my freshman year, the dorms had bunk beds, and I worried about falling from the top, but never did.

My parents were not especially concerned about the dangers of beds, bicycles, cars, drugs, alcohol, chainsaws, or lawnmowers when I was growing up. On the other hand they drew the line at motorcycles and guns. The only time I was seriously injured (concussion), it was bicycle related, FWIW.

I don't know how you do a cost-benefit analysis for society when nobody particularly agrees on the benefits of something.
