If you are placing your latex mattress on a solid surface like the floor, particle board, or plywood, you run a great risk of gathering condensation underneath the mattress and that can lead to the formation of mold and mildew. Typically, the best way to prevent condensation under your mattress is by using some type of ventilation system between the plywood and mattress like a coir bed rug
or moisture barrier
. This is usually the simplest and best solution compared to other options. With regrets, we do not sell the moisture barrier.
