Sadly few
My public nookie experiences have been limited, however, I did lose my virginity in a field (yes, to a human). I'm pretty sure that, on that occasion, I was rubbish. To be fair the agricultural surroundings didn't help, root vegetable crops do not a comfy mattress make.

More recently, I've discovered that office swivel-chairs have some potential for fun. I'm keen to test this out further, although I'm concerned that excess spinning could induce fighter pilot style blacking-out if blood is occupied elsewhere.

Office Chair
I can heartily recommend the office swivel chair as a sex aid. I have one at home & the (ex) missus loved kneeling up on it.............

Happy memories.........

^^this :-)
Although it's worth making sure that they're not the horrid cheap plasticky ones first...

Office chairs are good
Just make sure you don't recline too much and crash to the floor in an decidedly unsexy tangle of bodily parts/fluids.

I speak from experience.

I recommend
gas-lift ones. They dampen the vigor of the occupants' bounce. Also, assuming the position is girl-on-top, facing each other, she can slide her legs through the arm rests for support.

My old chair was the perfect size and shape for shenanigans like that.
