Product details


The Graco® Tranzitions™ 3-in-1 Harness Booster is designed to grow with your child and go with you, wherever your journeys take you—from car to carpool and beyond. This lightweight car seat transitions seamlessly from harness booster (22-65 lb) to highback booster (40-100 lb) to backless booster (40-100 lb) and features the Simply Safe Adjust™ Harness System, which adjusts your harness and headrest to 8 height positions, with no rethreading. It features two removable cup holders to keep your child happy, and a machine washable seat pad, body insert, and harness covers. To continue to meet industry standards, we have increased the weight minimum from 30 to 40 lb.

  • 2 easy-to-clean cup holders keep your child's drinks and snacks close at hand.
  • Open-loop belt guides help properly position your vehicle’s seat belt.
  • Seat pad, body support, and harness covers are comfortable and machine washable.
  • Graco ProtectPlus Engineered: a combination of the most rigorous crash tests that helps to protect your little one in frontal, side, rear & rollover crashes.
  • Meets or exceeds the child restraint criteria for a frontal crash test under the US FMVSS 213.
  • Side-impact tested for occupant retention solely with the built-in 5-point harness system.
  • Rear-impact tested based on the European Rear-Impact Crash Pulse.
  • Tested to Graco's RollSafe™ testing standard based on the European rollover testing procedure.
  • Be sure to check your local and state laws, as well as AAP and NHTSA recommendations, for car seat usage.
