  "question": "Which convertible car seats take up the least width in the back seat, leaving more room for a front-seat passenger?",
  "answer": "Britax Galaxy360 Slim Rotating Convertible Car Seat With SwivelSmooth Steel Ring: Reviewers with CPST training report the seat turns in a smooth motion on a closed ring of wheels-on-steel and that at 17 inches it is one of the narrowest rotating seats available. The seat measures about 21.5 in high, 22 in deep and 17 in wide.\nBritax Poplar S Convertible Car Seat 2-in-1: In this hands-on video the ClickTight steps were genuinely straightforward with no guessing about tightness, and the 17-inch width fitted tighter back seats it was tried in; the build felt solid when secured. Interior measurements cited from Britax are about 11 inches deep and 12 inches wide with a 14-inch shoulder width, so parents should judge harness fit on the child rather than on the numbers alone.\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 seat measures 20.5 x 17 x 23.5 inches.",
