  "question": "Which of these booster seats can be installed in the middle seat of a car?",
  "answer": "No checked fact states that any of these boosters fits a middle seat specifically. The seating requirements that apply are these. Britax UpNGo Click Backless Booster Car Seat: The booster must be used on a forward-facing vehicle seat with both a head restraint and a lap-and-shoulder belt. Britax UpNGo: It may only be used on a forward-facing vehicle seat that has both a head restraint and a lap-and-shoulder belt; side- or rear-facing seats are not allowed. Maxi-Cosi Tanza (BC197): The vehicle seat back must be upright, though its angle can be adjusted slightly to match the booster.",
