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.
