This Full size 8-inch Thick Memory Foam Mattress - Medium Firm has memory foam provides a great sleeping surface. In normal temperatures it is somewhat firm, but when you lay down, it starts reacting to the temperature of your body and begins to mold itself to your shape. Then, weight is evenly distributed along the surface, relieving pressure points and helping you to sleep more without tossing and turning. A significant feature of this mattress is our PRESSURE RELIEF SYSTEM that you can actually feel when you lay on the mattress. Special areas inside the mattress are more pliable and accommodating to the areas of your body that create pressure points: your shoulders and hips. Most people move during sleep and when you roll to your side, your shoulders and hips create pressure points that can disrupt sleep. Our pressure relief foam really does minimize these pressure points.
