In the summertime, you will witness a battle between the sun and your car seat. The sun rays make the place hotter.

So the baby passenger suffers a lot. The dark color seats are more affected by the sun. Some car seat has the metal buckle and other metal instruments.

That metal becomes hotter for the sun`s heat. It will create an unbearable discomfort for the child.

So it is better to avoid metal clips and avoid colored seat. The light color and metal-free seats are more preferred.
