Earlier quoted context omitted.
But… the children! Won't somebody think of the children! Oh, they did, you say? I see :)
To be honest, that thing is scary even for me as fit adult male. One little mistake and I could seriously hurt myself. Same for the children. I would be very uncomfortable letting my own child climb around on this to be honest. I would probably let it, but feel bad the whole time.
As a parent of two kids and a teacher, they don't make me nervous.
