What's the closest everyday thing to a wrestling ring?

the ring is made out of sections of wood with a slight spring covered by canvas. a few centimetres gap. so when you see a bump. it hurts..!!!

I've always heard the ground is pretty much like taking a bump in a ring. Not concrete, but the actual grass and dirt natural ground...just make sure there aren't any rocks or pointy things that can lobotomize you if you fall wrong.
