Why do mattress innersprings go "pyoing" without provocation?
I only notice it a few times a year, but just occasionally I hear a "pyoing" sound (like a spring being plucked) emitted from inside my mattress, even though there didn't seem to be any sudden movement that could have caused it. Why does that happen?

One of the coils was squinched down the last time you slept or sat on the bed; it finally popped back up.
