Just doing a quick suvey. Y'all actually clean it? And for instance if you had a pet that pee'd on it you wouldn't let it stay for 1 week and just lay your blanket over the pee and go to sleep on your bare matress?
My cat used to pee on the mattress before I got her fixed and I washed it right away w vinegar and water and would sleep on the couch while it dried... After she was fixed tho i just chucked it and bought a new mattress and just clean every few months cuz dust and stuff gathers. Who is not cleaning their animal urine stained mattress?
