Waterproof mattress cover

[Questl]

Been getting into a particular kink and wanted to get some firsthand recommendations for keeping things in the bed from soaking into the bed. Reviews online seem to trend specifically two ways: they love it, but it's never been put to the test, or it failed. Would love to hear from folks who've regularly tested their covers without failure; bonus for low noise.

Had a sub who was a squirter. The following can be used together or apart.
I’d recommend minimum the mattress cover. All other things can be washed. You can’t wash a mattress.
Crib pads
Waterproof sheets
Waterproof mattress cover
Plastic garbage bags or sheet poly plastic
Shower curtain
Towels as a top layer

As a Sissy Baby who has been wearing diapers for years now, I've wet the bed more than a few times. I use three mattress protectors on my Purple brand mattress. Purple makes a stretchy pul like protector. And I bought a similar one from amazon. But the best mattress protector is the fitted vinyl 6mm thick protector I bought from Babykins. Easily the best mattress protection I've ever used.
