Perfect for young children, the exclusive flip-wave design tailors to the growing child with one side slightly higher than the other. Start on the lower side and as the child grows turn the pillow over for a better fit. The contours naturally conform to the child's head providing vital support for proper neck and spine alignment. Micro-ventilating cores prevent moisture and heat build-up, keeping the child comfortable in any sleep position. Ideal for allergy sufferers, it is the only pillow that retains its shape after each and every wash.
