Enjoy the ultimate in comfort with the O by Neven® Arize pillow. Crafted with charcoal-infused memory foam you receive the benefits of memory foam – pressure relief and conformance. But there is more! When charcoal is infused, it forms a finer, more open-cell memory foam, providing a velvety feel and higher airflow, which means you will sleep cooler. Single pillow is available in either Queen or King size.
