Product Overview
Whether you’ve spent your day on the water, hiking mountains, or perhaps just enjoying some solitude in your van; you deserve a solid night’s sleep. For those who spend their nights in an RV, Camper, Boat, Van, or even at home. You know that icky feeling of a damp mattress. At DRICORE® we know how important it is to provide a space to allow airflow to pass through to keep you dry, whether it’s for your floor, or your mattress. When you’re cozy under your blanket and the temperature around you is cooler, this dichotomy can create unwanted moisture. This problem is amplified in smaller spaces where the temperature difference is more extreme and ventilation is inadequate, this is often the case in RV’s, Boat’s, and Campers. This leads to damp mattresses, and the buildup of potential mold and mildew over time. With DRICORE DuraDri™ you can say goodbye to damp mattresses. With our 2-year warranty you can be assured that DRICORE DuraDri™ will keep you elevated night after night to maintain airflow and provide the dry, comfortable sleep you deserve. For Twin Installation Place the DRICORE DuraDri™ mattress with the white dimpled surface facing down where the mattress will lay Place your mattress on top of the underlay Trim excess material as needed with scissors Enjoy a dry and comfortable sleep.

DuraDri elevates your mattress, creating a space for proper airflow to manage condensation caused by temperature changes.
