  "question": "Which car seats can switch from a harness to a booster as a child grows?",
  "answer": "Britax Grow With You ClickTight Harness-2-Booster Car Seat: Harness mode is for 11.3–29.5 kg (25–65 lb); booster mode is for 18.1–54.4 kg (40–120 lb). Nuna ROYL: In forward-facing harness mode with the vehicle belt and tether the seat is for children 2 years and up, from 30 to 65 lbs. It notes many boosters stop around 100 lbs, and treats the 120 lb booster limit here as a real advantage for longevity.",
