Inside the pillow is 70% shredded memory foam and 30% Everlon (also called Everloft). This gives the pillow a very comfortable, more traditional feel. It's perfect to pack in a suit case, use on an airplane, or in a car for long trips. It's guaranteed to never flatten. If it does flatten, simply tumble dry the pillow on low heat and it will instantly reshape to original thickness. The pillow is also anti-microbial, anti-bacterial, dust mite-resistant and hypoallergenic. This is due to the Everlon material. Dimensions: 11" x 14"
