Crash-tested with each car seat
Also look for higher forward-facing weight limits on 5-point harness seats, and keep your toddler in a booster seat as long as possible after he or she outgrows a regular car seat. Many seats today offer higher rear-facing weight limits, and this is a good option to choose if possible. You don’t have to turn baby forward-facing right at one year and 20 pounds. Use of after-market products often voids the car seat warranty. This includes head toddler carseat positioners and seat belt ratchets, which aren’t needed if you install the car seat properly. After-market car seat products aren’t crash-tested with each car seat and could cause injury during a crash. When buying a car seat, bypass all of the car seat accessories and installation aids.
