Vandwelling Beds: Memory Foam

[Srae29]

Cheers everybody, I have a question concerning the prevention of mold with my Sealy foam mattress in my van.
Right now it lays on a 3/4" plywood a out 14" off the floor. What have others done to prevent mold happening with the mattress? Put something on the plywood between it and the mattress? Or put the mattress in a protection cover? At the moment I haven't had to deal with condensation yet, but I'm concerned about mattress foam mold and would like to know how others have had to prevent mattress mold.
Any suggestions and ideas are appreciated.
Cheers

This is what I put under (and around the walls where my mattress is up against them): https://www.mattressinsider.com/mattress...ntion.html

Others have drilled a lot of holes in the plywood support.

My bed platform is designed to lift in three separate sections so I can access storage beneath (12V fridge/laundry hamper/deep storage for seldom used stuff and excess food supplies).

Since I'm in to the fridge multiple times a day and the laundry  hamper area at least once a day, I have had no problem with any kind of moisture build up between the mattress and the plywood and that includes a very rainy summer in the PNW where it rained at least part of the day for 51 days straight!!

Getting even temperatures above and below the bed is the key more than anything. If the below plywood area is shut off and colder than the above bed temps then you're going to get condensation. I noticed this one winter in an apartment when I had the mattress on the floor which was carpet over concrete. I thought that it was a broken pipe seeping upwards but it turned out to be condensation - cold meeting warm!

Simply putting a comforter/throw or blanket between the mattress and the plywood will do little to help. If you're  not building the bed to lift up for access to storage and it's going to be closed off in all directions then either drilling holes or using slats will work if you don't want to put in a commercially made separator to prevent condensation build  up.

I have an old afghan blanket/throw that my son's ex-wife didn't want. The kind that people used to drape over the back of their sofa in the 70s and 80s. It is very thick but with a very open weave. I put it under my bottom foam, then fold it over to go under my top layer of foam. Every time I move I pump air in and out between those layers of foam and the board underneath. No accumulation of moisture yet, even when the windows are dripping wet. 

You might be able to find one at a thrift store somewhere.

Thanks for the stories and suggestions. I better find something for ventilation because I dont use anything now. So far, I havn't had a problem.
I've been so focused on preventing mold in my van ever since I watched a video of a young guy constracting a serious infection from a moldy mattress in his van.

While still in the planning stage of a build, I'm using a perforated Muscle Shelving Unit (Walmart) reconstructed into a bed platform. Shortening the legs to 13 inches, and bolting 2-shelf configurations together to make a raised platform provides air flow and under bed storage. In a different application on top of a plywood platform, I bolted single shelves together side by side, with only pvc connectors as legs, to provide air flow.

I find it to be more of a problem in the winter. good ventilation is the key. highdesertranger

Here's a thought.

My foam mattress (standard foam with a memory foam topper) is in a "bedwetter" bag. Not because I can't control my bladder (yet) but because I might spill on it or it might get rained on. I'm guessing it works as well keeping atmospheric moisture out. I haven't had a mold/mildew problem in the six years I've been on the road, even though my mattress sits on a solid sheet of plywood. My experience isn't really a test since I stick mostly to low humidity regions.

Does it crinkle or make noise when you move around? Does the mattress tend to slide around more?
