From material fro the cushion is a delight, whether the baby rolls later on his stomach and his face is on the pillow, air it gets, despite the fine breathable fabric anyway.
The depression in the middle is quite sufficient to keep his head out safely, without which there is more dents in the skull area.
However, it gets to me only 4/5 stars because although the pillows could prevent a worsening of the deformity of the skull so far, but not a significant improvement showed what I had after 5 weeks of use, unfortunately, perhaps mistakenly hoped.
Overall I would really recommend it to anyone freshly baked parent this pillow preventively, it is so low and with its fabric so breathable that it only benefits, rather than the so often feared damage by pillows in newborns, brings with it.
