Twenty one of the 72 seats tested were rated best bets by the institute, while seven are considered good bets. However, the IIHS says eight of the seats it tested, it can't recommend for consumers.
"This is the Evenflo Generations 65. It's one of the boosters we don't recommend. The main problem is the lap belt is too high on the stomach. Another issue is the shoulder belt is too close to the neck where it will cause comfort issues. The child is liable to wriggle out so that the belt won't be in position to protect him in a crash," says David Zuby with IIHS.
There are 72 booster seats in this test.
