The terry cover will protect the main cover of the Pebble car seat from soiling. It can quickly and easily be removed for washing unlike the actual car seat cover, should you have a baby that is ‘sticky'. The summer cover is a good investment as the car seat can not be used without the main cover and they do take a long time to dry due to the padding. The cover also is designed to protect the car seat from fading in the sun during the summer months. Made from cotton terry, it is fully machine washable and can be tumble dried.
