  "title": "Convertible car seats with a seat-belt lock-off",
  "question": "Which convertible car seats have a lock-off that holds the seat belt tight?",
  "answer": "Maxi-Cosi Sela All-in-One Convertible Car Seat: The round-up describes the seat-belt lock-off as forward-facing only, which differs from the maker's description of a lock-off arm usable in both rear- and forward-facing positions. For forward-facing the top tether is taken from its storage compartment and the seat is placed as flat as possible against the vehicle seat before the belt is routed behind the lock-off arm, which is then closed and pushed down.\nCybex Gold Eternis S Sensor Safe All-In-One Car Seat: The rear- and forward-facing lock-offs are one-way, buried in the belt path and difficult to use. They need lots of slack and a flossing motion; the technique that worked differed from the manual's pull-down instruction. First installations are difficult, though the lock-offs loosen with repeated use. Consumer Reports found LATCH installation much better than vehicle-belt installation. It rated rear belt and forward belt 3/5, rear and forward LATCH 5/5, rear-facing fit 4/5, forward-facing fit 3/5, booster fit 4/5, and ease of use 3/5. It also found both lock-offs hard to see and use and said the manual lacks clear forward-facing lock-off instructions.",
