I bought this slide to use as part of an indoor bunkbed. I didn't realize that there wouldn't be some sort of support included (which wouldn't have mattered because it'd need a custom one to be used indoors anyways). I received the yellow slide and attached it to a 60'' platform. I was at first concerned about the length of the slide making it flimsy, but the kids were able to slide down just fine. I even had a (small) adult try it, and it holds up fine!

Pros: Can be used indoors (no drilling into the ground)
Cons: Side rails aren't super high, could make people a little nervous
