  "question": "Which car seats fit three across in a single back seat?",
  "answer": "Clek Liing: Clek says the narrow 16.9 in width saves space and makes 3-across seating possible. Clek Fllo: The Fllo was described as the narrower, lighter alternative to the Foonf, at 25 lb, easier to move and install, and suited to three-across in mid-size sedans. Britax One4Life Slim: Shown fitting three across beside a Britax Poplar convertible and a Willow S infant seat; with the cup holders fitted it is wider than the bare 17.5 in width. Britax Marathon ClickTight: When a ClickTight Boulevard was installed beside a ClickTight Marathon in a 2010 Honda Odyssey third row, the second seat overhung the vehicle seat and the buckle sat under the Boulevard, so the pair did not install correctly next to each other.",
