The quality and functionality of this pillow is great. It really support the neck and can be used not only in the travel seat but also in the pushchair. I use it for my 7 months old daughter in backward facing pushchair to set her head in the correct position, especially when she is alseep.
This particular pillow is in XS - EXTRA SMALL size for babies 0-12 months which should be stated in the desription and it wasn't.
Wish I knew that the same pillows are also available in other sizes: SMALL (1-4 years), MEDIUM (4-8 years) and LARGE (8 years+).
