2019 IIHS Booster Seat Ratings: Best Bet and Beyond

Does your booster rate as a Good or Best Bet?

Every year, the Insurance Institute of Highway Safety (IIHS) releases their annual fit ratings of belt-positioning booster seats. Because proper seat belt fit on children is so important to their safety in a crash, having a booster seat that adjusts the seat belt easily for both parent and child is paramount. Fortunately, since the IIHS has released their ratings for years and given access to their testing protocol to manufacturers, we have many more excellent choices than ever before. This year IIHS evaluated 13 booster models as Best Bets.

Beginning last year, IIHS used a new dummy designed specifically for these tests called Jasper (Juvenile Anthropomorphic Seat-belt Position Evaluation Rig). IIHS worked with Humanetics, the dummy’s manufacturer to design Jasper, which represents a 45 pound 6 yr old.

What makes a “Best Bet” booster seat? The booster should correctly position the seat belt on a typical 4-8 year old child in most vehicles. A correctly positioned seat belt will fit low on the lap, touching the thighs, and cross the shoulders about half-way over the collarbone. The shoulder belt should move freely through the belt guide if you have a highback booster.

But remember, your vehicle may not be “most” vehicles and may have a different belt geometry. Always try before you buy, if you can, and hold onto the box and receipt in case you need to return the booster.

“Good Bet” means that the belt fit will be acceptable in most vehicles and these boosters shouldn’t be automatically shunned because they aren’t “top tier.”

“Check Fit” means just that: it may fit a larger child better than a smaller child in some vehicles or vice versa. I’ve used “Check Fit” boosters quite successfully before with my kids in my cars—it definitely doesn’t mean you should chuck the seat out with the bathwater.

What Does Good Belt Fit Look Like?

Most kids need boosters until ages 10-12, news that can be shocking to many first-time parents. Seat belts are designed to fit adult bodies and until children reach adult size, they need a restraint that helps the seat belt fit them or they are at risk of severe injury or death in a crash. The 5-Step Test was designed to help parents determine when their kids fit safely in a seat belt without needing a booster seat.

Sometimes it can be confusing and not at all clear as to whether the seat belt is sitting on the child correctly or not. When evaluating belt fit, it’s always best to dress the child in tight-fitting clothes that don’t bunch; the worst outfit to choose is jeans and a sweatshirt.

Highback boosters with headwings generally have the shoulder belt guides attached and adjust in height. Please check your instruction manual on how to raise the headwings to adjust the shoulder belt position on your child’s shoulder. It’s not comfortable for your child to have the headwings pressing down on your child’s shoulders, or even behind their shoulders like we frequently see because parents don’t know to lift the wings up.

Not Recommended Boosters

For the second time in as many years, there are no new boosters on the “Not Recommended” lists; however, that doesn’t mean there aren’t still Not Recommended boosters from past years still being used or for sale as leftover stock. One seat, the Safety 1st Summit 65, is still being manufactured. It is worth looking at the list to make sure a booster you’re using or considering isn’t on this list. These boosters demonstrate consistently poor belt fit.

What about the Incognito and Mifold?

The Safety 1st Incognito and Mifold are belt positioners, but not boosters; they don’t raise children up to position the seat belt on their bodies. As such, IIHS doesn’t rate them.

For the complete 2019 IIHS Status Report with listing of all previously ranked boosters, visit the IIHS website:

Given the number of Best Bet boosters available, chances are high that your booster kid is using one. However, if you’re using a booster that doesn’t garner that coveted Best Bet label, remember to do a fit check yourself in every vehicle you use the booster in since seat belt geometry varies so much. If you have a booster on the Not Recommended list, we do suggest that you find a dedicated belt-positioning booster from the Best Bet list and it need not break the bank.

If you’d like more guidance on which booster to choose, we have our own list of Recommended Carseats with a section on booster seats.



Is It Safe to Check Your Carseat When You Fly?


The issue of how to best handle flying with kids and their carseats is something that comes up often. Many safety-conscious parents will bring the carseat with them knowing that their child will need to use it once they reach their destination. I applaud all those parents for doing the right thing! However, for a variety of reasons, most parents don’t actually bring the carseat onto the plane and use it for their child during the flight. I suspect that many of those checked seats that I see on the baggage carousel belong to children under the age of 2, who wound up as lap babies on the flight. For the record, here at CarseatBlog, we have always recommended that you buy a ticket for your child (regardless of their age), bring their carseat and use it on the plane.

Newborn on airplane – safe and comfortable!

Regardless of why parents chose to check their carseats, the fact remains that most travelers flying with carseats in tow do check them instead of lugging them through security and using them on the plane. And seats checked with regular luggage probably get tossed around and manhandled the same way luggage does. I somehow doubt that the baggage guys suddenly look at the carseat and decide to handle it with care so they don’t crack the EPS foam, know what I mean?

But what if you’ve already traveled with your carseat and checked it? Perhaps even multiple times? Is it still safe to use? There are some CPS advocates that will argue that a checked carseat could have sustained significant damage during the time it was out of your sight and should be replaced as a precaution. Some might actually go so far as to suggest that the checked carseat is now “as good as crashed”. I personally think that stance is over the top but I understand the logic behind those opinions. I’ve seen how beat-up my luggage is sometimes when I reach my destination. Plus, many frequent flyers have witnessed first-hand some of the abuse that luggage endures as it’s loaded and unloaded from the aircraft.

GM Recalls Certain Chevy, GMC & Cadillac Models Due to Faulty Seatbelt Retractors


General Motors is recalling several 2018 and 2019 GMC, Chevrolet, and Cadillac vehicles due to seatbelt assemblies that might not switch to locking mode when used to install child restraints.

Normally with these vehicles, caregivers would lock the seatbelt by pulling the webbing all the way out when installing child restraints. In the affected vehicles, seatbelt assemblies for the second and third row may fail to lock when the webbing is pulled all the way out. This can leave the seatbelt and child restraint loose, and could prevent the child restraint from working properly in a crash, increasing the possibility of injury.

What vehicles are affected?

This recall includes 15,800 vehicles from the following models:

  • 2018 Chevrolet Suburban
  • 2019 Chevrolet Suburban
  • 2018 Chevrolet Volt
  • 2019 Chevrolet Volt
  • 2018 GMC Yukon XL
  • 2019 GMC Yukon XL
  • 2018 Cadillac CT6
  • 2019 Cadillac CT6
  • 2018 Cadillac Escalade ESV
  • 2019 Cadillac Escalade ESV
What’s the fix?

GM will notify owners. Dealers will inspect the rear-seat retractors and will replace the assemblies if necessary.

What do I do in the meantime?

GM’s official position is “await notification,” but people can take steps in the meantime. If you own one of these vehicles and have a child restraint installed with the seatbelt, check to make sure the seatbelt is locked. (Once you have installed the child restraint, pull the seatbelt webbing all the way out, then feed the excess back into the retractor. If the belt is locked, you shouldn’t be able to pull the webbing out again.) If the belt locks, there is nothing to worry about at this time. If the belt does not lock, you have some options:

  • Try a different seating position in the vehicle
  • Install the seat with lower anchors (LATCH) if your child is within the LATCH weight limit and the seating position is equipped with lower anchors
  • Use a child restraint with a built-in lock-off
  • Use a locking clip

It is important to note that this problem does not affect the emergency locking function of the seatbelt. That means the belt will still lock as usual in a crash or hard stop when it is restraining an adult, an older child not using a child restraint, or a child using a booster seat where the seatbelt goes over the child’s body.

General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, “Occupant Crash Protection.”

Consumer Reports Crash Test Findings: Britax Frontier and Pioneer, Cosco Finale & Harmony Defender Receive BASIC Rating

Some Combination Harness/Booster Carseats Break in CR’s Crash Testing

This week Consumer Reports published an article which detailed some of their findings during crash testing of a category of car seats better known as Combination Seats. Also known as harnessed booster seats, harness-2-booster seats, or toddler booster seats, these are forward-facing only carseats with a 5-point harness that can also be used as a booster seat utilizing the vehicle’s seatbelt. There are many popular seats in this category including the Graco Nautilus, Evenflo Maestro and Chicco MyFit.

The article from Consumer Reports has created quite a buzz and we know that our readers are looking to us to provide thoughtful and reasonable commentary on this issue. Keep in mind that until the crash test results and full rating of all the combination seats tested in this round are released, we are forced to focus on the limited information we have been provided with so far. As always, we will do our best to present the facts in a clear and concise manner so that parents can understand the scope of the issues and CPS Technicians can help educate the families we work with.

Here’s what we know so far, “In CR’s crash evaluations, testers found that the load-bearing components at the rear of the seats broke when tested with dummies whose weight was near the seat’s limits for its harness system.” The Britax Frontier ClickTight Harness-2-Booster, Britax Pioneer Harness-2-Booster, Cosco Finale DX, and Harmony Defender 360 all experienced some sort of structural damage during this very challenging crash test. The Britax Pinnacle ClickTight Harness-2-Booster wasn’t tested but is very similar to the Frontier model. Therefore, it’s possible that the Pinnacle would have experienced issues similar to what was observed with the Frontier if it had been tested.

Before we get into what went wrong, it’s essential that you understand more about the Consumer Reports crash test and how it differs from the federal government’s crash test that all carseats need to pass in order to be sold in this country.

Why did Consumer Reports create their own, unique crash test for child restraints that already pass all the safety standards in Federal Motor Vehicle Safety Standard (FMVSS) 213?

Consumer Reports wanted to provide consumers with comparative information on carseats. By developing their own test protocol, the aim was to determine which seats offered an extra margin of safety in certain crash conditions simulated by the new tests. We know all carseats sold in the U.S. are required to meet FMVSS 213 standards but we also know all carseats aren’t the same. The goal here was to determine which seats could hold up well under tougher crash test conditions that were also more “real world” than the 213 compliance tests.

How is this test different from the FMVSS 213 tests?

Currently, 213 compliance testing involves a test sled with a bench seat from a 70’s era vehicle with lap only belts and LATCH anchors. There is nothing to simulate interaction with a front seat and carseats aren’t tested with 3-point lap/shoulder belts. The seats are tested at approximately 30 mph. Unless you’re driving around town with your kids secured in the back seat of a ’73 Impala (with LATCH anchors), the current FMVSS 213 crash tests are pretty useless in determining how your carseat might actually perform in a crash in your vehicle.

The Consumer Reports dynamic sled test was designed with more real-world vehicle conditions in mind. They chose to use a 2nd row captain’s chair (with lap/shoulder belt, of course) from a model year 2009-2012 Ford Flex. The geometry of the vehicle seat and the stiffness of the seat cushion made it an ideal “average” of what you can expect to find in modern vehicles. They included a “blocker plate” (pictured below) mounted in front of the vehicle seat to simulate a front seatback surface for potential interaction with the carseat and/or the dummy inside. This is important because in the real world we know children are often injured when they come into contact with the back of the front seat during a crash. Consumer Reports also chose to run the tests at 35 mph because that is the speed at which vehicles are crash tested in the government’s New Car Assessment Program (NCAP). It just makes sense to test carseats at the same speeds that we test vehicles for crashworthiness.

Is a crash test at 35 MPH really that much different than a test run at 30 MPH? 

Yes, it can be a very big difference. An additional 5 miles per hour may not seem like a big deal, but the difference can increase the energy in a crash by almost 40%. Combined with a more severe crash “pulse”, the peak forces on an occupant could even double.

How many crash tests were each combination seat model subjected to? 

Each model was subjected to several different crash tests (using a new seat each time) depending on the weight rating of the product. All of these seats were tested with the Hybrid III 3-year-old dummy (ATD) who weighs 35 lbs. All of these seats were also tested with the Hybrid III 6-year-old ATD who weighs 52 lbs. The seats rated up to 65 lbs. (Finale & Defender) or 70 lbs. (Britax Pioneer) were also tested with the 6-year-old ATD who was weighted using a standard weight kit from NHTSA that adds an additional 10 lbs., making the ATD weigh a total of 62 lbs. Since the Britax Frontier ClickTight is rated up to 90 lbs. using the harness, this seat was tested with both the 6-year-old ATD and the 10-year-old ATD. This was the only seat in all the combination seats Consumer Reports tested that was subjected to testing with the 10-year-old dummy who weighs 78 lbs. It’s also the only combination seat on the market that is rated up to 90 lbs. with the harness.

Britax Frontier ClickTight Crash Test Results:

The headrest adjustment and harness support structures on the Frontier ClickTight broke when tested with the 6-year-old dummy (ATD) who weighs 52 lbs. The Frontier CT was not tested with the weighted 6-year-old ATD since its harness capacity is 90 lbs. Instead, it was tested with the 10-year-old ATD who weighs 78 lbs. In this very severe test, the supporting structure around the metal retention bar on the back of the shell broke, and the retention bar and harness pulled through the back of the shell. When this occurred, the harness loosened significantly. This is definitely not the news anyone wants to hear, but keep in mind that the Britax Frontier CT (and the similar Pinnacle CT model) pass all federal crash test standards when tested with these same ATDs (both the 6-yr-old and the 10-yr-old). The Consumer Reports crash test was designed to be more challenging in order to establish which child safety seats provide additional margins of safety above and beyond the federal crash test standards (FMVSS 213). Since the Frontier ClickTight had issues in their testing, it receives only a “BASIC” rating for crash protection, meaning that it meets all the required and necessary standards from NHTSA (the federal government) but it does not provide greater margins of safety, in their opinion, when tested with the bigger ATDs who weigh more than 50 lbs. For the record, there were no issues observed when Consumer Reports tested the Frontier CT with the smaller 3-year-old ATD.

According to a statement from Britax:

“The Britax Harness-2-Boosters tested by Consumer Reports are safe when used as intended and in accordance with the instructions and warnings contained in the user guides.” Britax also said the company would “continue to stay engaged with Consumer Reports to benefit from their perspective.”

Britax Pioneer Crash Test Results:

The headrest adjustment and harness support structures of the Britax Pioneer broke when tested with the 6-year-old dummy (ATD) who weighs 52 lbs. Since the Pioneer is rated to 70 lbs. with the harness, it was tested again with the weighted 6-year-old ATD (62 lbs.). In each of the tests with the 6-year-old ATD and the weighted 6-year-old ATD, the headrest adjustment and harness support structures broke but the harness did not pull through. Since the Pioneer had issues in CR testing, it receives only a “BASIC” rating for crash protection, meaning that it meets all the required and necessary standards from NHTSA (the federal government) but it does not provide greater margins of safety, in their opinion, when tested with the bigger ATDs who weigh more than 50 lbs. The Pioneer did not exhibit any structural issues when tested with the 3-year-old ATD. 

Cosco Finale Crash Test Results:

The structure that anchors the tether strap to the shell broke in 3 out of 3 tests with the 6-year-old dummy (ATD). This enabled the tether strap to extend, which resulted in increased head excursion (meaning the dummy moved farther forward than it would have otherwise). This occurred in both tests with the 6-year-old ATD (52 lbs.) and in a single test conducted with the weighted 6-year-old ATD (62 lbs.) This breakage also resulted in pieces of sharp plastic in areas that may contact the child. Due to these issues, the Cosco Finale receives only a “BASIC” rating for crash protection, meaning that it meets all the required and necessary standards from NHTSA but it does not provide additional margins of safety, in their opinion, when tested with the bigger ATDs who weigh more than 50 lbs. When tested with the 3-year-old ATD, the Finale did show signs of stress in the tether area, but it did not break through.

Dorel Juvenile, the parent company for Cosco, responded in a statement by saying:

“The Dorel Cosco Finale combination child restraint has performed well with respect to all NHTSA crash performance requirements and in real-world use. There are over 350,000 Finales in use and there have been no injuries reported.” The company noted that CR’s testing varies from NHTSA’s standards. “Dorel takes the results of the Consumer Reports testing seriously and is currently evaluating the findings,” the statement said.

Harmony Defender 360 Crash Test Results:

The support hardware on the back of the shell (near the shoulder area) broke in 3 out of 4 tests with the 6-year-old dummy (ATD). This allowed the harness to “pull through” the shell and loosen as the dummy moved forward. This occurred in one test with the 6-year-old ATD (52 lbs.) and in both tests with the weighted 6-year-old ATD (62 lbs.) Due to these issues, the Harmony Defender receives only a “BASIC” rating for crash protection, meaning that it meets all the required and necessary standards from NHTSA but it does not provide additional margins of safety, in their opinion, when tested with the bigger ATDs who weigh more than 50 lbs. The Defender did not exhibit any structural issues when tested with the 3-year-old ATD.

Response from Harmony:

In a statement to CR, Harmony stated that its seat meets all current U.S. federal standards. The company also said that CR’s testing “did not take into account practical matters such as how the car seat fits or installs into vehicles, which affects overall safety greatly …” Harmony pointed to what it described as “several discrepancies within Consumer Reports’ testing that differs from other testing, both independent and internal” that would “impact the testing results greatly.” The company did note that it “appreciates all comments from customers as well as independent bodies such as Consumer Reports as all such information is always used in the ongoing improvements of all our products.”

CarseatBlog Recommendations:

If you already own a Britax Frontier or Pioneer: If your child meets the weight and height criteria for using the Frontier/Pioneer in booster mode (at least 40 lbs. and 45″ tall), consider whether or not your child may be ready to use the seat as a booster. Consumer Reports recommends switching to booster mode at 40 pounds or replacing the seat. We suggest that parents make their own choice on when to transition to booster mode based on the child’s maturity and booster readiness. If your child isn’t developmentally ready to ride safely in a booster (most kids under age 5 are not, but there are exceptions), and you don’t have another appropriate seat to put them in, then leave your child in the harness.  

Reality can’t always be ideal and there are tradeoffs in situations like this. Every parent or caregiver has to weigh the pros and cons and make decisions based on their personal circumstances. If you have a child who meets the weight and height criteria for using the Frontier or Pioneer in booster mode but the child is too immature to stay properly seated in booster mode (using just the seatbelt), or if the child has special needs which make a 5-point harness necessary, then the risks of using the seat as a booster probably outweigh the potential risks of experiencing some sort of structural failure in a severe crash. However, if you are keeping your neurotypical 8-year-old in the Frontier or Pioneer harness just because he/she still fits, you may want to reconsider.     

If you already own a Cosco Finale: Consumer Reports recommends switching to booster mode use at 40 pounds (as long as the child is at least 43″ tall) or replacing the seat. We think parents should make their own choice on when to transition to booster mode based on the child’s maturity and booster readiness. If your child isn’t developmentally ready to ride safely in a booster (most kids under age 5 are not, but there are exceptions), and you don’t have another appropriate seat to put them in, then leave your child in the harness. If the child is too immature to stay properly seated in a booster (using just the seatbelt), or if the child has special needs which make a 5-point harness necessary, then the risks of using the seat as a booster probably outweigh the potential risks of experiencing some sort of structural failure in a severe crash.

If you decide to use the Finale as a booster, please note that the shoulder belt guide is problematic in some cars, not allowing the seatbelt to retract properly. However, the shoulder belt guide on Finale is only required when it’s necessary to achieve proper belt fit and therefore it can be skipped for many taller kids who don’t need it for proper shoulder belt positioning. 

If you already own a Harmony Defender 360: Given that the harness pulled through the shell in 3 of 4 tests at 52-62 pounds, we suggest that parents consider switching their child to booster mode if the child weighs more than 40 pounds, they fit well, and they are mature enough to ride in a booster full-time. Otherwise, we agree with Consumer Reports that a replacement harnessed seat should be found, though the Defender could be used with the harness until a replacement is available.

If you’re shopping for a new carseat: The complete CR crash test results and rating of all the combination seats tested in this round will be released soon (available to subscribers) but we don’t have an estimate on when everything will be ready. From what we know, they are finishing the analysis of crash results but still need to complete the ease-of-use and fit-to-vehicle criteria in order to calculate the final overall score for each seat in this category. To their credit, CR’s policy on all the products and services they evaluate is to report any issues they identify in testing as soon as they are validated, even if the full ratings aren’t finished yet. If you are feeling uneasy and want to use a seat that you know did well in their testing, the Graco Milestone All-in-One, Graco 4Ever 4-in-1, and Chicco NextFit Convertible have already earned a “BEST” rating for crash protection in the convertible or all-in-one category. Keep in mind seats in CR’s convertible category, such as the Chicco NextFit, do not convert to belt-positioning boosters.

Additionally, while we don’t know for certain, we anticipate that the Graco Nautilus, Graco Nautilus SnugLock, Evenflo Maestro Sport, Evenflo Transitions/Evolve and Chicco MyFit will all be included in this round of testing. We don’t expect there to be any major issues with these combination seats simply because they would have been called out already if there were. However, none of these seats are rated beyond 65 lbs. with the harness. The Britax Harness-2-Booster seats are still the only combination seats on the market with harness weight limits above 65 lbs. Considering how problematic it is to test and pass regular FMVSS 213 crash testing with the 10-year-old ATD, it’s unlikely that we will see any other manufacturer introduce new products with harness weight limits beyond 65 lbs. 

Final thoughts and comments:

We understand that this news is stressful to parents and caregivers who already own these seats. We’re not going to sugar coat the situation or tell you to ignore the Consumer Reports findings. Everyone needs to find their own comfort level with this new information. Some parents and caregivers will lose confidence in the products they are using and others won’t. Some will look for alternative products while others will continue to use the seats they have. Some will transition the child to booster mode while others will continue to use the harness. We can’t tell you what the best choice in your situation is. What we can do is provide you with all the information you need to make the best possible decisions based on the available information. Ultimately, it’s always the parent or caregivers responsibility to make the decisions on how the child will ride in the vehicle. For those of us who are CPS Technicians, this is our gospel. We stay current and up-to-date in this constantly evolving field so we can educate others. Sometimes there are no easy answers but it’s our responsibility to provide accurate and unbiased information so parents and caregivers can make informed decisions.
