A new review of car booster seats finds that some of them do a poor job of positioning children to fit in their seat belts.
The Insurance Institute for Highway Safety and the University of Michigan Transportation Research Institute say 13 seats don't put children in the best position to be protected in a crash.
One manufacturer on that list, Evenflo, says it conducts extensive tests of the seats and says the study was "misleading." Another, Graco Children's Products, says "safety is always a top priority." Other child seat manufacturers say their products meet and exceed federal regulations.
It was the first time the Insurance Institute issued evaluations for booster seats.
Booster seats are typically used by children between the ages of 4 and 8.
(The Institute, which conducts crash tests of new vehicles, did not recommend: Compass B505, Compass B510, Cosco/Dorel Traveler, Evenflo Big Kid Confidence, Safety Angel Ride Ryte, Cosco/Dorel Alpha Omega, Cosco/Dorel (Eddie Bauer) Summit, Cosco Highback Booster, Dorel/Safety 1st (Eddie Bauer) Prospect, Evenflo Chase Comfort Touch, Evenflo Generations, Graco CarGo Zephyr, and Safety 1st/Dorel Intera.)
