iComfortPro, Serta's most advanced mattress, features layers of premium latex foam in a 5-zone comfort system. The new iComfortPro features support zones made from latex that retains its shape to promote better spinal alignment, while contouring your body and providing even pressure relief. Why latex? Latex foam is durable and breathable, with contouring comfort and pressure relief where you need it most. It is naturally temperature regulating. A quilted top features a cool-to-the-touch fabric to help you fall asleep more easily.
