Prevent Moldy Mattresses! Moisture protection for mattresses- project

WHO WANTS MOLDY MATTRESSES?

There are many reports about moisture issues from underneath RV mattresses.  This is a real issue and one not only that can cause rotting wood structure of your bed platform but also cause unhealthy mold to form there as well as literally on the outside and inside of your mattress itself.  Not good!

This issue becomes more prevalent with those who full time in their rigs or especially for those who are in high humidity areas or who winter in their rigs where internal heat temps versus external surfaces (e.g. in ours the wheel wells under our bunks which essentially are “the outside”.  This converging of a heated surface (body heat, furnace heat) and a cold surface will cause sweating and condensation.

After researching and doing a lot of checking of reviews and posts from full time RVers we found the following product.  We ordered it last spring and did our install before beginning our 2019 camping season.

This is the roll, as received and standing atop my curbside Avion bunk.  Note I am not sure all bunks come with the cut out handles like this.  Could have been something done by one of our rig’s previous owner, but a great idea even though you also have the below bunk cabinets!

It is sold by the foot and is I believe 4 ft wide. So for our Avion bunks @ 34″ we did have to cut to fit both width and length.  The stuff is very sturdy but also simple enough for me to cut with sturdy kitchen shears.

GATHER ITEMS NEEDED:

  1. Sturdy Kitchen Shears
  2. Metal tape measure or yard stick
  3. An extra pair of hands
  4. Double faced Heavy Duty  minimum 2 inch wide Velcro strips or large squares (more about this later!)
  5. Duct or Gorilla Tape (if you have a double or queen bed and will need to piece together)

STEPS:

Measure width and length of your bed/bunk.  If you have an Avion floor plan like ours and two bunks, simply double the length of one bunk for what total length you will need to place for your order.

Place order, will be shipped directly to you. Is not super heavy. Watch for when company may have sales on free shipping!

We took our measurements of bunk base, first cut new mat the correct length, then marked and measured the correct width and cut. Note- we have a slight molding lip on our bunk base that is intended to create a bit of a lip to prevent mattress sliding off.  So we cut our mesh mat to also fall just inside that small lip.

For the actual install, we followed the manufacture’s recommendations and we placed the “mesh pocket” side down on our plywood bunk base, then placed the mattress on top of the breathable fabric side of the mesh.

** after using for a few trips this way we did find that the mesh side was very likely to cause our whole mattress to slide a lot and often found our mattresses half into the hallway after being on the road.  A fix we plan to do this year is to take a few large strips of the 2 inch wide sticky back Velcro strips and place them a few places on the mesh side to stick down onto the wood bunk base.  The small molding on the bunk base that DID keep the mattress itself in place was not enough to hold the mesh layer in place.  The mesh layer is a woven plastic and a bit slippery.  We anticipate that the Velcro strips will do the trick and highly suggest this modification.

After securing down with the Velcro strips, replace mattresses down on top of fabric side of new mesh mat.

Sleep well!
