After much back and forth bestellt.Unsere daughter has become used to it over time to sleep only on their backs and has thereby get a slight head plates. In order to avoid further such cushion ordered. The material is well made. Even the reference, it is breathable. Did it even kept on the nose and it works with the breathing. Is indeed important if the child should turn times. Already after 2 weeks had seen a significant improvement. Now the head slowly arched back nice and round. I recommend to all parents who have such a problem, think and do not invest too much time. The small but are well worth any money and therefore their health. Both cushions and washable. The pillow I would now bring out nothing of material, the so is the head nicely supported, even though it might by the manufacturer. Pediatrician recommends.
