Where is the best place to store my seed phrase?

Since the Voyager debacle and everything else going on out there in the crypto world, I decided it was best to finally move my crypto into a cold wallet storage. I am a very unorganized and forgetful person so I have been holding off on making this decision. Not your keys not your Bitcoin or whatever everyone says. So where is the best place to keep a seed phrase so it doesn’t get lost but is still safe? My first initial thought was to keep it at the bank I work at in a safe deposit box which would cost me a small annual fee but I’d also not like to rely on some one or some company keeping my belongings safe, which is the whole point of having a cold wallet storage in the first place. I have my seed phrase written down on three separate papers and plan on giving one to my parents to store in their fire proof safe, but what should I do with the one that is in my possession? Thank you in advance!
