  "question": "Which infant car seats can be installed using the vehicle's seat belt?",
  "answer": "Britax Willow S: The Alpine base can be installed using either a vehicle seat belt or lower connectors and has a visual installation indicator. Chicco KeyFit 30: This owner's car had no LATCH, so they installed the base with the vehicle belt; that was fairly simple, but getting the shoulder belt to lock after routing it through the base was tricky to repeat. CYBEX Cloud Q SensorSafe Infant Car Seat: Installing the base with a vehicle belt was substantially harder: belt-guide tabs, belt bunching, even slack removal, and closing the tensioning plate could require considerable effort or another hand.",
