Sex Slings: yay or nay?

[wonderkin]

So I love having sex in a sling but I don't have the space for one at my place. So I'm looking at the "Porta-Plow" on Fort Troff's website and its kinda the same thing, but you lay on your bed instead of hanging from a stand or the ceiling. Seems like a very simple way to get the same type of experience without a lot of the hassle or cost. The one on Fort Troff is expensive compared to what I found on Amazon, but it would still be way less than an actual sling and hardware.

So, a few questions if anyone have experience or opinions around slings and whatever this watered down version is called.
Have you ever used one of these things?
Does something like this have a standard name?
and, has anyone ever seen something like this used in a porn movie?

I do want to get one, but that also got me thinking it would be cool to watch someone in a porn using one. I couldn't find anything on few different porn sites, but I think thats cause I didn't know what to search for "leg straps", "body sling", "bed restraints"?

Ok, thanks, have a great day guys!
