The institute named a record 31 seats among its "best bets," meaning they "correctly position a vehicle safety belt on a typical 4- to 8-year-old in almost any car, minivan or SUV." Brands with more than one "best bet" included Britax, Graco, Harmony and Recaro.
Engineers evaluated 62 booster models. Some dual-use seats, which can work as high-back or backless boosters, were evaluated twice, so a total of 83 seats were tested.
Five seats were rated "good bets," providing "acceptable belt fit in most vehicles." Nearly half of the models - 41 - fell into the "check fit" category, meaning they "may provide good fit for some children in some vehicles."
Only six models were "not recommended."
