Uber and Lyft provide car seat options in their apps for riders in New York City. There are standard Lyft and UberX vehicles in the city that are equipped with car seats. A child must be between 31 inches and 52 inches tall and weigh between 22 pounds and 48 pounds to ride in a car seat. The car seat option in Uber and Lyft adds $10 to the total fare. The companies may expand to additional cities, which will be reflected in updated ride options in their apps.
