Similar, except the idea of ruining my perfectly good mattress by sleeping on it sans sheets is enough for me to put sheets on. I simply can't imagine being like angh, fuck it, sleep on mattress.

I remember moving out of my family home with my mom and brother after my parents split, I was 19 or 20, spent the whole day carrying shit. Get to my room, it's mattress, box spring, floor, and I'm exhausted. I still took the extremely lazy route of grabbing my sleeping bag and sleeping in it on my mattress.

And for anyone unaware here, a little PSA, putting your bare skin on your mattress is a great way to get a stinky, oily mattress that is uncleanable. It's why mattress covers exist, ton insulate that nice mattress from your awful stink (myself included). Once it's ruined, its ruined.
