After much experimentation with the car seat, different clothes and pillows I finally ended up with this wedge pillow with the proper method to avoid back pain during long car trips. At first I had to get used to it, because it sits higher than previously and also have to stand the legs differently. At least I had to change, because I'm not very big the. But after my first really long car ride (over 800 km one way) I am very satisfied. No more back problems. The pillowcase touches his pleasant and can be pulled off for washing. The price is great. I can only recommend this wedge pillow.
