This beautiful baby support pillow is ideal for your baby! Its ergonomic shape provides great neck and head support for your infant and can help prevent or correct plagiocephaly (flat head syndrome). And isn't it adorable, too!? - Can be used laying down, in car seat, swing, stroller or under a baby gym (should not be used in upright position, i.e. car seat, until your baby has full neck control!) The ErgoPillow was intentionally designed narrow, to fit your baby ergonomically (unlike most travel neck pillows that push your baby's head forward, toward the chest). Often times babies have a preferred side that they always lay on, which can lead to deformation. The sides of this ErgoPillow are very soft to help avoid deformation, yet give firm side support. This ErgoPillow is made from the softest polyester velour fabric. It is filled with 100% non-allergenic polyester fiberfill.
