With the Dreamfoam Hybrid mattress, our advanced top fabric (typically offered only on luxury beds) delivers cooling relief on contact. Keeping you the ideal temperature all night long. Our gel memory foam provides optimal pressure point relief with just the right amount of responsiveness, allowing for less motion transfer and more restful nights. Additionally, our high-density base foam adds durability while reinforcing individually encased coils. Our hybrid design sports open cell technology in both the foam layers and the inner coils—to prevent heat retention and allow for optimal airflow and breathability. Pairing our premium quilted top fabric with gel memory foam will keep you at the ideal temperature all night long. Up to 760 individually encased coils and a high-density base foam provides durability that's guaranteed to last. RV Bunk size, 42 inches by 80 inches
