The seat cushion can be said to be the closest place to the baby, and its design will vary depending on the size of the stroller or the folding method. Generally speaking, cars that can be used for both sitting and sleeping are more spacious and sturdy; Some lightweight umbrella car seat cushions are more spacious and thick; Some lightweight umbrella vehicles, due to their lightweight requirements, usually only have a single layer of fabric support.

Another thing to note is that the cushion should not be pressed too deeply after being loaded, that is, the support should be sufficient, otherwise the baby will feel uncomfortable sitting. In addition, to protect the young head, a soft designed headrest cushion can be chosen.
