  "question": "Which convertible car seats include a top tether, and how is the tether attached?",
  "answer": "PEG Perego Primo Viaggio Kinetic Convertible Car Seat: The maximum child weight for top tether use is 65 lbs.\nCybex (sold as Cybex-dc) Callisto G 360: In independent simulated frontal crash tests with a forward-facing 6-year-old dummy installed with lap-and-shoulder belt plus top tether, the tether system released before the head reached its most forward position in all three tests — the tether hook broke twice and the sled's tether anchor broke once; in a weighted 6-year-old dummy test the tether strap sheared off after the double webbing section. Technicians describe it as a true one-time install with the seat belt because the tether strap stays attached in both directions, with a tall 18-inch top harness height, a belt tensioner and an anti-rebound base design; you still need to lock the seatbelt at the retractor.",
