The deluxe ten-inch memory foam RV mattress provides both comfort and support in one compact package. It consists of three layers including a heavy duty polyurethane base foam, an upper memory foam layer and airflow foam in between. The middle layer allows the mattress to breathe while the other two are responsible for temperature control and zero motion disturbance. When it comes to firmness, this deluxe product is not too firm or too plush either. It is somewhere in the middle. Moreover, its contouring properties mean that it can easily adjust to your unique body shape so your side of the bed becomes a relaxing haven for your muscles and joints. Each mattress comes with its very own four-way zipper cover that can be easily removed for washing.
