The Ella Jayne Performance Collection matches our classic style with attributes needed to help you fully refresh each day. Our Ella Jayne Shredded Memory Foam Pillow will not go flat! Suitable for all sleepers, we use a premium hypoallergenic bamboo cover and shredded memory foam filling which provides a slow and deep sink that supports healthy posture for your head, neck, and spine. The zipper on the side empowers the sleeper to easily adjust the height and fullness of the pillow by removing or adding back more foam fillers to fit their specific needs as they sleep. The shell of the pillow is viscose rayon derived from bamboo making it soft to the touch.
