An infant seat is a seat that faces the back of the car, never the front. Infant seats are designed to fit newborns up to about 20-22 lbs. Most are designed to be used as a car seat and carrier, and have some type of handle to allow you to transport baby from car to restaurant, home, shopping, etc. Most come with a base that stays in the car, there are a few that do not have bases. Most seats that have a base can also be installed without it.
