  "answer": "Graco SlimFit3 LX: At 16.7 inches wide, the reviewer calls it one of the narrowest convertible car seats and says if it does not fit a tight setup, likely nothing else will. The seat is about 16.7 inches wide at the shoulders, with a base about 11.5 inches wide, making it one of the narrowest convertible seats tested. Graco confirmed that three SlimFit3 LX seats fit three-across in a 2019-2021 Toyota RAV4 in several configurations, including all forward-facing, all rear-facing, and mixed modes.\nDiono Radian 3RXT Safe+ Max: Unfolded, the seat measures 16 in wide, 17 in deep and 28.5 in high.\nEvenflo All4Stages Slim 4-in-1 Convertible Car Seat: 16.9 in. family cars or rentals\nBritax (listed by the store as Britax-dc) One4Life Slim ClickTight All-in-One Car Seat, SKU E1D407A-OB: The seat is 17.5 inches wide, described as slim enough to fit three across in most vehicles.\nGraco SlimFit 3-in-1 Narrow All-in-One Convertible Car Seat - Sydney: The original SlimFit was introduced to solve back-seat space problems and is described as narrow and affordable. The rotating cupholders can be turned to reduce the seat's width.",
