Enjoy the cooling comfort of the Azul memory foam mattress. We took our most advanced memory foam mattress (Serenity), and combined it with our most popular memory foam mattress (PacBed Original), to create the perfect reflection of both in one awesome bed! This American-made mattress features CoolRest® Adaptive, a functional finish, that keeps you cool and comfortable by infusing smart thermocules into the cover and top layer of the memory foam. This phase-changing technology regulates body temperature by pulling heat away from your body. Not only does it keep a warm sleeper comfortable, but these smart thermocules also add warmth back to the sleeper, for those who sleep a little cooler. The layers of memory foam and support foam provide a medium soft feel our customers have come to love so you will sleep cool and comfortable right out of the box!
