Neither Megan no Miz use sheets or a mattress pad. They both sleep directly on top of the mattress. It was mentioned that sleeping on a bare mattress is a symptom of some psychological disorder and not too uncommon. Miz has cats and Megan has dogs which sleep with them in the bed with their dirty paws. Miz often has gay partners over to fuck him in his "assholeo" which leaves faecal particles or turd chunks in the bed.
Megan famously used her child's bed for the photo shoot of her inserting a weasel up her anus while a greasy chicken wing and pack of camels lay on the bed next to her. However Megan is known to bring random partners home for sex and group sex sessions which include "pegging" in her own bed.
TJ's bed has sheets even if he rarely or ever changes them. TJ also spends fewer nights in his own bed, and if TJ passes out in his car he will just sleep there all night. TJ is known to stay with whatever rando male and female he is hooking up with rather than bring them to his place. Even TJ's greasy, sweaty hambeasts Autumn Allamong and Sylvanna Bocook prefer to sleep in their own beds when they have sex with TJ. TJ's dog "Sniffers" was put down and does not sleep with him any more either.
In the filthy mattress competition, Miz and Megan rule. TJ, eesh, Myeesha, Carlos, Katie, Kristy, Meade, etc. are not even in the running. Ben Lamka is in his own category sleeping in tent with a gay hobo.
