Our Supreme pillows are made from the same high-density material used by NASA to cushion astronauts during lift-off and landing. It actually react to your body's shape and temperature by cradling the neck and head to evenly distribute weight and pressure with a soft comfortable cushion feeling, unlike the less expensive molded low-density visco-elastic memory foam pillows that have a sponge rubber feeling. Our Supreme pillows offer the maximum pressure relief thus helping to reduce pressure points, alleviate tossing and turning, and aids in the relief of tension, neck aches, and head aches. The result is a more comfortable, restful sleep, so you feel more energetic all day.
