I have a playset like that @Debbie1061 and families like it. As to liabilities, best to discuss with a lawyer. I imagine you could say something like "use at your own risk" in your house rules. But I was once told that even if you had guests sign a full agreement, they could still sue. All that in mind, I don't think a playset is a huge risk. Mine is not very high and has deep mulch underneath, so even if a child fell I doubt they'd really be hurt.
