A stroller and car seat combination is a stroller system that connects the car seat to the stroller's frame. This makes it easier to transition the child from the vehicle to the stroller.
The car seat itself becomes part of the stroller once connected and can be front or rear facing, depending on the model. Marketed as a "travel system" at retail locations, the combination is designed for convenience while maintaining the safety of the car seat during foot travel. Jogging models have features like cup holders, MP3 player housing and built-in shocks for outdoor activity. They can commonly be identified by a single bicycle-style tire in the front.
