The Serta Perfect Sleeper® is designed to help solve the five most common sleep problems. The plush Cool Twist® Gel Foam gently conforms to your body, offering pressure-relieving comfort to reduce tossing and turning. An exclusive individually wrapped coil system offers outstanding back support and supports the areas where you need it most, while the TrueSense® Design system isolates motion to minimize the impact of partner movements. Cool Balance® Technology combines high-performance heat and moisture-regulating fabric with an overall mattress design that helps promote airflow to ensure the ideal sleep temperature. The enhanced Total Edge® Foam Encasement increases the edge-to-edge sleeping surface to prevent edge roll-off.
