I’m two days (and nights) into sleeping on a futon mattress on top of my old, severely dented mattress. This has been a learning experience that has left me not only a little loopy for reasons I’ll speculate on later, but that has me thinking about just how easy it might be to detect a pea beneath twenty mattresses, if those mattresses are thin, old, or scrungly enough. On one hand, I’ve learned that there are many types of back pain, some of which you might only feel as you slowly recover from worse pain. On the other hand, now I know what it means to climb into bed as an adult. And how my last partner felt every time we both stayed at my place. I mean, it’s not like my current pillow-topped mattress was particularly low (the perfect height for me to settle back on without needing to really bend at the knees, but now my bed surface is above waist-height on me (I’m six-foot-three, for reference) so I have to actually CLIMB onto it’s weirdly spongy surface. Sure, neither mattress feels like that on their own, but the weird way that pressure settles through the futon mattress into the foam-topped spring mattress beneath makes it all feel like an old, damp, slightly mildewy piece of memory foam that springs back instantly. It’s mildly upsetting to touch with my hands, but the sensation disappears once I’ve got most of myself into the bed, so I only have to put up with it for a few seconds at most as I clamber.
