  "title": "Signs a Child Is Ready for a Booster Seat",
  "question": "How can a parent tell whether a child is ready to move from a harness to a booster seat?",
  "answer": "Clek Olli: The child must be 40–57 inches tall and weigh 40–120 pounds; Clek recommends a minimum age of 4 years. Beyond meeting the stated limits, the child must sit upright without slouching and keep the belt properly positioned.\nBritax Skyline 2-Stage Belt-Positioning Booster Car Seat: High-back mode is for children weighing 40–120 lb and measuring 44–63 inches; backless mode is for 48–120 lb and 46–63 inches. In either mode, the child must be able to remain seated properly. The retailer describes it as suitable for families with children aged 4–12, but the manual bases use on fit and sitting behavior rather than a stated age range.\nPEG / Peg Perego Primo Viaggio Flex 120: It is one of the tallest boosters on the market; the highest belt guide is 22 inches, with a 63-inch height limit and 120-pound weight limit, and no vehicle head restraint is needed. A booster without armrests gives a child more freedom to move, so maturity matters for sitting correctly.\nMifold Comfort: In hands-on fit testing, the lap belt with mifold Comfort landed far forward on a smaller child's thighs, outside the recommended range; in a crash the pelvis could move forward without engaging the lap belt. The reviewer notes about 80% of original mifold fit photos also had unacceptable lap belt fit. Store page features: meets/exceeds US FMVSS 213b; designed for ages 4+; slim enough for three across in most vehicles; regulated for use during travel; ideal for road trips, carpools, taxis, rental cars, daily use; shoulder belt guide clips and slides.",
