Only the 0.0 pillow is not dual-chambered, this single-chambered pillow ensures consistent comfort with a Boost blend fill throughout. Boost crown provides firm, elevating support with ventilated channels that increase airflow throughout the pillow. The zip-off, removable and washable cover creates a clean and healthy sleep environment. Personal performance size: 20" wide by 26" long. Comes with a 1-year manufacturer's warranty.
