The Insurance Institute for Highway Safety (IIHS) has released their list of booster seats they do and do not recommend. On the recommended side, there’s been a significant growth this past year, with 21 Best Bets and seven Good Bets. Out of 72 booster seats the safety organization tested, eight booster seats didn’t get recommended.

For a booster seat to earn a Best Bet or Good Bet nod, it must properly position a three-point seat belt over a 6-year-old testing dummy. While performing these tests, IIHS experts measure seat-belt fit in a variety of vehicles. They also use high-back and backless booster seats as well as combination child-safety seats. The ratings do not take into account any type of crash tests.

According to the IIHS, children ages 4-8 who are placed in booster seats are 45 percent less likely to be injured in a car crash than children using only seat belts.

Read the lists of IIHS’ Best Bets, Good Bets and seats not recommended after the jump.
