I use a $13 mattress protector to save the memory of my mattress. Works like a charm. I envision it like a sensory deprivation chamber for my bed.
It doesn’t remember all the times the cats threw up on it. It doesn’t remember me sweating out all the liquid in my body every night for an entire summer. It doesn’t remember all the.. activities.. and it doesn’t remember that time I spilled spaghetti nor the time I spilled soup.
My bed remains blissfully unaware. It treats me right and I do the same.
(Also a $13 protector extends the functional life of a mattress by literally years, bodies are fucking gross and all that soaks right in and ruins the structure.)
