The Den-Dry Mattress Underlay is a terrific way to battle mattress condensation. When we sleep, our bodies produce an insane amount of heat and moisture. Heat and moisture plus a cold surface equals condensation, making soggy bedding, mold, mildew, and a ruined mattress. RVs and boats are closed spaces that concentrate moisture. If you spend a considerable amount of time outdoors, you'll likely notice that pesky mildew smell, most often in winter.

The Den-Dry Mattress Underlay offers the ability to keep a mattress elevated enough to allow airflow. Its spun polymer and plastic enable your bedding to stay elevated above the bulkhead, even with two humans sleeping on the mattress generating BTUs all night long. This creates a barrier that allows air to flow, keeping the mattress out of condensation's way. No more of that funky smell while making the bed.
