A riddle that i dont know the answer to.

A coffin.

I think the classic version is, "he who makes it has no use for it, he who buys it does not want it, and he who uses it does not know it."

Edit: I was wrong, too.

"Who makes it, has no need of it. Who buys it, has no use for it. Who uses it can neither see nor feel it. What is it?"
