Can't access the website, but sounds like the German approach [1]. In the past years, I can see that some new playgrounds being built in my area in France also incorporate more risks, which is nice.
Compared to playgrounds when I was a child in the 80s, they were much safer, there was no sand, only that black bouncing floor (which might be toxic) and above all there was very little to do.
Same when we visited our friends in Toulouse.
It was much worse than the playgounds we have in Hong Kong that at least have decent slides, climbing bars, etc...
One thing that I've noticed is missing from both countries though are swings. We have them in Hong Kong but instead of just being a flat piece of wood on which you can stand, sit and do other things, it's more of a safety seat like you'd see in a baby chair.
Do you have any reason to believe this?
