This is the pillow with 24 fluffed chambers that provide constant support throughout the night. Unlike floppy feather pillows that allow the head to sink too deeply into its loft and flatten over time, this model provides a quilted top with two dozen cushioned cells that allow the pillow to maintain consistent support regardless of your angle or position. Each individual chamber is filled with naturally hypoallergenic polyester down alternative fibers and the pillow features a soft 100% cotton surface. The pillow?s reverse side provides a traditional flat surface when desired. Machine washable. White.
