"We evaluated the safety belt fit boosters provide, not crash protection," says Institute president Adrian Lund in the press release. "This is because unlike child restraints, boosters don't restrain children in crashes. They simply position children so lap and shoulder belts are in the right place to restrain them."
"We'd expect the 10 best bets to improve belt fit for children in almost any car, minivan, or SUV," Lund says. "Likewise, it's clear that kids in the 13 boosters we don't recommend aren't getting the full benefit of improved lap belt fit. These boosters may increase restraint use by making children more comfortable, but they don't position belts for optimal protection."For a list of the "not recommended", "best bet" and "good bet" seats, click here.
