A Memory Foam Back Cushion Pillow can be a great solution for people with lower back pain issues. The outer fabric of this pillow is specially designed to allow airflow and prevent the buildup of heat from the body, which will help keep your neck cool and dry and prolong the pillow's lifespan. The support of this pillow comes from two layers of memory foam. The top layer is high-density memory foam, which absorbs pressure and slowly rebounds for even support throughout the night. The bottom layer is high-resilient memory foam, which is denser and helps to prevent your head from sinking too far into the pillow.
