How to combat moisture pooling under my mattress?

I have a memory foam matress on top a cot. Every now and then I need to sun dry the mattress and cot from a decent amount of moisture trapped between the two. Is there a way to keep the moisture out or even just reduce it?

  • Sailor here.

    I've put those plastic shower tile mats under my mattress. The ones that help with draining water while keeping your toesies dry.

    It lets enough air flow through that it can dry up under the mattress. Others just drill a bunch of airholes in their berths.

  • Embrace the moisture. Become one with the mold.

    • Been there done that. Got some good gigs as a mildew-man but eventually the mycelium grafting into my neurons was starting to cause motor function issues so I had to give that life up. Good times though it felt like microdosing on cube shrooms 24/7 overall I'd do it all again if I had the chance.

      One of my more iconic acting roles you might recognize :

  • You need better air flow.

    I had the same issue as a student, when I lived in that pocket-sized 1 room 'apartment' with barely any airflow coming through a single and tiny window. The only solution I found to be working was, each morning, to lift the mattress and store it on its side with the bottom/downside face part of it not facing the wall, and let it like that for the rest of the day. The air would do its magic.

    I also raised the bed frame that was very close to the ground.

  • Cotton topper / mattress protector. Helps to catch and distribute heat and moisture. In my experience also improves sleep quality

  • Drill holes in your wooden base so moisture can escape, or change the base to slats for the same reason.
