  "title": "Narrow convertible car seats for three across in a back seat",
  "question": "Which convertible car seats are narrow enough to fit three across in a back seat?",
  "answer": "Britax Poplar ClickTight Convertible Car Seat: Seat is 17 inches wide without cupholders and 20 inches with them. Good for small backseats; on the most upright rear-facing recline it is one of the most compact rear-facing convertibles on the market. Front-to-back footprint depends on recline setting.\nBritax Poplar S ClickTight Convertible Car Seat: The Poplar and Poplar S are described as among the skinniest car seats on the market, at 17 inches wide externally. The article notes it is a 2-in-1 convertible, not an all-in-one, so there is no booster mode and another seat will eventually be needed.",
