The best toddler car seats, in general, accommodate children who weigh 22 pounds to 40 pounds and who are at least 1 year old. Toddler car seats can only be used forward facing, and have three-point or five-point harnesses. Some toddler-to-booster car seats convert to belt-positioning boosters for children weighing 40 to 80 pounds.

Once your child has reached the highest weight or height allowed by the manufacturer of the seat for rear-facing, she can ride forward-facing in a convertible seat. However, it is best for her to ride rear-facing to the highest weight or height allowed by the manufacturer of her car safety seat. She should ride in a forward-facing seat with a harness until she outgrows it (usually at around 4 years of age and about 40–65 pounds).

There are 5 types of car safety seats that can be used forward-facing.

  • Convertible seats—seats that “convert” from rear-facing to forward-facing seats.
  • Forward-facing toddler seats—these seats can be used forward-facing with a harness for children who weigh up to 40 to 80 pounds (depending on the model).
  • Combination forward-facing/booster seats—these seats can be used forward-facing with a harness for children who weigh up to 40 to 65 pounds (depending on the model) or without the harness as a booster (up to 80 to 120 pounds).
  • Built-in seats—some vehicles come with forward-facing seats built in. Weight and height limits vary. Read your vehicle owner’s manual or contact the manufacturer for details about how to use these seats.
  • Travel vests—these can be worn by children between 20 and 168 pounds and can be an alternative to traditional forward-facing seats. They are also useful for when a vehicle has lap-only seat belts in the rear.
