Garden play equipment on decking

[oneplustwoplustwoplusone]

Kids are 6 and 5 so grown out of our Wendy house and tiny tikes car etc. Our lawn is slightly sloped, bumpy and the foxes love digging in it. We do have a large ish bit of decking at the back. Has anyone put play equipment on decking? Would I need to put anything underneath? Or is it a non starter as it needs to be anchored down?
I was looking at something like this https://www.plumplay.co.uk/products/climbing-dome-frame?variant=44111677161645

Falling off that on to hard decking would hurt a lot more than falling on to grass, on that basis I wouldn’t put something like that on decking tbh.

I do and I have rubber fall mat under neath

@MotherOfCrocodilesoh where did you get the rubber mat from? Is you play equipment free standing?

Amazon. Our play equipment is anchored to an adjacent brick wall. I’d think you could get brackets to fix it to the decking boards if decking is sound. You can get them for fence posts and pergolas.

Decking rots so I would not trust something like that on it.
