While you might be tempted to skip it or your child might be begging to go without, hold fast for safety. Booster seats are the last car seat safety hoop to jump before you're done with car seats forever; the finish line is in sight!

Our favorite booster seat is the Nuna AACE. This high-quality choice offers the best crash-test analysis, a rigid LATCH connection, and ease of use. It also has a reasonable price compared to convertible car seats, although it is higher than the average price for a booster seat.

If your budget is tighter, we recommend the Chicco KidFit Air Plus 2-in-1, which could be the best fit for most families. This comfy booster includes a leg support lounger and is very easy to use. If it is out of your budget, the Chicco Kidfit ClearTex Plus 2-in-1 can save you even more money and offer similar protection.

We've tested more than 100 car seats, including the 17 boosters we purchased for crash testing and side-by-side comparison in this review. We spent months testing and using each booster, including a crash test analysis, ease of use, weight, and more. We can help you discover which seats offer additional protection and work best for every goal and budget.

If you are unsure which type of car seat is right for your child, check out our Best Car Seats Review. We've also tested infant car seats and the top-ranked convertible car seats for older babies.

Editor's Note: This booster safety seat review was updated on September 5, 2026, with the addition of the Nuna Lumn, and a retest of the crash testing on the Nuna Aace.

CONS

Heavier

The Nuna aace is a standout booster seat with exceptional crash test analysis. It earned some of the lowest sensor data for the HIC and chest clip in the group (lower is better). It is a relatively narrow seat, measuring only 16 inches in our tests, and it features rigid LATCH connectors to keep the seat in position when no one is sitting in it. The AACE is easy to install, and both the headrest and seat bottom are easily adjustable. We love the padded headrest, with our child tester stating, “I could totally nap here.” The belt path and shoulder positioner are easy to use, but you will need to lift the headrest for optimal access. Buckling is a mixed bag that requires ensuring the seat is pushed to the opposite side away from the buckle, but once it is, our tester had no difficulty getting the job done on her own.

The AACE is not a lightweight booster at a measured weight of 15.9 lbs in our tests. While it isn't as lightweight as the BubbleBum, weighing in at 0.9 lbs, it isn't as heavy as the Nuna Lumn, which weighed over 26 lbs in our tests, but the Lumn also doubles as a convertible seat and has a 5-point harness to better justify the heft. The aace also didn't have the best padding in the seat or back area, with our child tester complaining, “It feels like a rock with a blanket on it.” But not many of the boosters offered much for comfort padding. If comfort is a priority, the Chicco KidFit Zip Air Plus 2-in-1 was a massive hit thanks to extra padding and leg support. Overall, the Nuna is impressive and the option we think is right for most families with the right budget and an interest in crash test analysis.

PROS
Better crash test results
Easy to install
Leg lounge padding
Zip-off cover
CONS
Uncomfortable headrest
Rougher headrest fabric

The Chicco KidFit Zip Air Plus 2-in-1 is an excellent seat for most families. It offers better crash-test analysis results at a price that feels like a steal. These factors make it great for those on a budget or as a second seat. With comfortable features like supportive padding and additional leg lounge padding, it is easy to see why kid testers gave it a big thumbs-up during testing. Our child tester stated, “I could sit here all day; so relaxing.” The Air Plus is an easy-to-use option for parents and kids, and the higher-quality materials imply it will last as long as you need it to. In our tests, the Chicco was easy to secure to the car via push-style LATCH connectors and a quick-tightening strap at the front. It sports dual cup holders and a snack accessory box with a flip-top lid. The Chicco can be switched to a backless booster for easier travel while remaining one of the lightest high-back boosters in the group, weighing only 11.8 pounds.

The Air Plus headrest and fabric cover aren't our favorites, and the Peg Perego Viaggio Flex 120 offers a more comfortable headrest and adjustability to help ensure better napping comfort. Our tester reports, “I don't like the fabric; it is weird to have the rougher fabric in the head and face area.” The Chicco is also somewhat wide, with a base that measured 18.2 inches in our tests. While this is nothing compared to the Britax Grow With You ClickTight+ at 21.5 in, it is still wider than options like the UPPAbaby Alta v2, which is 16 in wide, and has similar crash test results. Overall, this Chicco is an impressive option that offers something for everyone, with higher-quality materials and a design that clearly considers both passengers and parents.

Weight range: 40-100 lbs | Booster weight: 10.3 lbs
PROS
Tight budget-friendly
Relatively lightweight
CONS
Just below-average crash analysis
Good quality for the price

The Chicco KidFit ClearTex Plus 2-in-1 is a straightforward, no-nonsense booster that secures to your vehicle using LATCH. This relatively lightweight option (10.3 lbs in our tests) earned an above-average overall score and performed well across most tests. It is easy to install using LATCH connectors to prevent it from being a projectile if no one is in the seat, super easy to use, and better quality than most options in even higher price ranges. As our tester stated, “It is a great overall seat, even if it isn't a standout for any one thing. I wasn't disappointed.”

This Chicco is somewhat wide, measuring 18.4 inches in our tests. While not the widest in the group, it is wider than the average, which hovers closer to 16 inches. This extra couple of inches didn't cause us trouble buckling in, but it could come into play with seating three across the same back seat. The UPPAbaby Alta v2 is another budget-friendly option with a width of only 15.5 inches, making it a great choice if space is at a premium. The KidFit also doesn't have standout crash test performance results. While it performed well enough and doesn't raise concerns, it isn't the best fit for those seeking the best crash test results. The Nuna aace earned top marks in crash-test analysis, but it costs more than double that of the KidFit. Overall, we like the KidFit, and so did our kid testers.

Bells and Whistles
Chicco informs us that the entire KidFit booster lineup uses the same base and varies only in the fabric and the bells and whistles each option offers. We tested the version with the leg rest and a version that is no longer shown on their website. However, they confirm the ClearTex Plus 2-in-1, and all others are essentially the same boosters, with a new design for the LATCH pull border plate and the fabric they offer.

PROS
Better crash analysis

CONS
Expensive
No armrests

The Peg Perego Viaggio Flex 120 is an impressive high-backed booster we really love. This booster achieved better results in crash test analysis than the average booster in our tests, bringing better sensor data from both the head and chest sensors to the table. It is highly adjustable for kids of various sizes, making it easy for both parents and kids to use. It is a high-quality option that provides more cushion and features for comfort than the average booster. Our tester says, “This is a great option for kids of different sizes because it has so many adjustment points, including width.”

The Peg is on the expensive side for the group, and for families on a budget, the Chicco KidFit Zip Air Plus 2-in-1 could be a better fit, with similar overall scoring and a price that is almost half. The Nuna aace earned better crash test analysis results, so it can save you money and bring somewhat better safety potential. The Peg also doesn't offer armrests. While we didn't think this was a huge problem, and our child tester didn't miss them, it is something to consider if your child wants them or will use them. The Peg Perego Viaggio Shuttle Plus 120 is similar to the Flex, but it has armrests and the same crash-test analysis score and price, making it a potential choice if armrests are a deal-breaker. Overall, if your budget allows, the Peg Perego is a great all-around option that didn't disappoint us.

CONS
Poor quality
No back

The BubbleBum is a booster we love for what it is, but we encourage you not to ignore what it isn't. This option is lightweight, weighing only 0.9 lbs in our tests, rolls up in its own travel bag, and is one that is uber-easy to take on travel or for little ones to carry for carpooling or camp. The similar Hiccapop UberBoost weighs slightly more at 1.1 lbs. The BubbleBum is easy to use, and the inflated bottom is comfy enough. Our kid tester remarked, “I like the blow-up cushion over the harder plastic boosters.” The BubbleBum earned an average score for crash test analysis, beating out the other travel and backless options we tested. We love that this seat provides potential protection in situations where little ones might not use a safety seat at all, and we think it is an excellent choice for a second seat or frequent travel.

This booster tends to shift under passenger weight and could cause trouble for some passengers with chronic adjustments or longer thighs. Kid testers report, “You can't shift around very much, or you'll need to adjust the booster a lot.” The Chicco KidFit Zip Air Plus 2-in-1 used in a backless configuration could be the better solution if comfort is paramount. The Chicco offers more versatility, as it can be used with the high back when convenient. It also doesn't provide any side protection against intrusion into the vehicle by external objects during an accident, which is why it's not our favorite for everyday use. However, if your little one needs a booster for travel, camp, or carpool situations, it is hard to find something better suited for the task than the BubbleBum.

The BubbleBum performed better than other backless boosters, but it was not a top performing in our testing commissioned through MGA Research. However, it has passed federal guidelines and is consider safe.   Credit: GearLab & MGA Research

How We Tested


We purchased 2 of each booster car seat in this review, one for crash testing and one for in-house and real-world use. We install each product in multiple cars to assess its fit, ease of installation, and usability. Children utilize the seats in real-life situations, and we record their opinions and feelings as part of testing, providing us with insight into comfort and ease of use without adult assistance. We combine all test results, including crash test analysis, to rank competitors and award winners.


Testing for booster seats is divided across five rating metrics:

  • Crash Tests (35% of overall score weighting)
  • Ease Of Use Tests (25% weighting)
  • Weight/Size Tests (15% weighting)
  • Comfort Tests (15% weighting)
  • Quality Tests (10% weighting)

We tested the quality of the materials and design for potential concerns like the Evenflo cup holder popping off without too much effort.   Credit: Abriah Wofford

Boosters undergo more than 24 individual tests to rank and score their performance relative to the competition. The most critical booster metric is crash-testing analysis, which accounts for 35% of the overall product score. This metric's overall result is derived from the crash test results, specifically the head injury criterion (HIC) and chest sensor clip (G) data. The second most important metric is ease of use, as many crash-related injuries result from a seat not being used as intended or as the manufacturer outlines.


Over time, we've purchased and tested more than 23 booster safety seats. Our testing puts each booster seat through a multi-point performance analysis that considers everyday functionality and more. We've spent years and hours using and testing boosters to determine what makes one better than another.

Why Trust GearLab


We've been testing safety seats since 2014, including commissioning crash tests at the same facility (MGA Research) that works with the National Highway Traffic Safety Administration (NHTSA) on its car seat tests. Our team is led by our founder, Dr. Juliet Spurrier, a board-certified pediatrician, uses her experience in the medical field to choose products with safety and ease of use in mind, the two factors that play a key role in keeping little ones safe during a crash. In-house testing is performed by and under the guidance of our onsite Certified Child Passenger Safety (CPS) Technician, Bob Wofford, father of 7. Bob works with Editor-in-Chief, Wendy Schmitz. Wendy, a mother of 2, uses her science background to analyze crash test results and ease of installation. She has written the car seat family of reviews since the first version in 2014 and knows more about car seats than almost anyone.

Analysis and Test Results


This review includes the details you need to make a well-informed decision on which booster seat is the best choice for your child and your budget.

Under the guidance and supervision of a NHTSA Certified Child Passenger Safety (CPS) Technician, we spent several months testing and rating every product in this review. We created a set of comprehensive tests based on our convertible car seat review and used these results, along with the crash test data, to determine the scores and rankings for each option.

Booster Time

Experts agree that children should stay rear-facing until at least age 2. The recommendations from both the American Academy of Pediatrics (AAP) and NHTSA are that babies stay rear-facing as long as is allowed by the seat, and at the very least until they are two years old. Children can move to a booster as young as four years old. Still, despite the convenience of a booster, BabyGearLab agrees with the experts that children should stay in their 5-point harness car seats as long as the manufacturer's recommendations allow. Depending on the car seat, this shift from a 5-point harness usually happens between 40 and 65 lbs. While parents love marking milestones as their little ones grow, transitions from one safety seat to another should not occur until your child has reached the seat's maximum limits as defined by the manufacturer. Each time you move to a new level of safety seat, the protection it provides decreases. Don't be in a hurry!

Also, don't rush to ditch your booster (even if your child complains and begs). Safety regulations are there for a reason. The recommendation is 4'9" tall before moving from a booster to the vehicle seatbelt. Once again, we recommend that you keep children in boosters until they reach the manufacturer's recommended limit.

Each booster we test is compared side by side to the competition. While each option has met the federal government's minimum safety guidelines, they are not equal in form or function, nor do they all offer an additional margin of protection compared to the competition (according to crash testing).

Worse Value
Better Value

What's the Best Value?


While safety seats are not the category where you should sacrifice potential safety for a lower price, there are budget-friendly boosters with impressive performances across key metrics that most families can afford. The Chicco KidFit Zip Air Plus 2-in-1 is a great-value booster with one of the better crash-test scores in the group. The Chicco KidFit ClearTex Plus is also a compelling option at a lower price, with only slightly lower crash-test performance. The BubbleBum is also inexpensive, but given its lower scores across most metrics, we think it should be a travel-and-carpool-only booster. Its lower price means saving the hassle of moving your everyday seat or carrying a high-backed booster while traveling.

Crash Test Analysis


We contracted with the same crash test facility used by the National Highway Transportation Safety Administration (NHTSA) to conduct our booster seat crash tests. We test the products at a faster rate than the speed outlined in the federal requirements (FMVSS 213) and on a sled that better mimics modern-day vehicle seats.

We analyzed the crash-test sensor data from each booster's crash-sled dummy to determine how they performed relative to one another. To help you better understand crash tests, we've included comparison graphs using the actual crash test results in each booster's gear review, and summarized them below.

What are the most critical details from crash tests for analyzing results?

  • The risk of head injury
  • The risk of chest injury

A detailed analysis of automobile crash injuries for children indicates that head and chest injuries are the cause of the most significant risks of severe or fatal injuries.

All Tested Products Provide a Basic, Safe Level of Protection
All seats included in this review are assumed to have met the minimum federal safety standards. Therefore, all of the boosters we tested provide at least a basic level of crash safety protection. Our primary focus for crash testing is to identify boosters with crash test performance results that exceed the federal requirements by a wider margin. The crash test sensor data suggest that these seats may potentially provide an additional level of protection compared to other booster seats in the group.

Understanding the Head Injury Criteria (HIC) Score


For the crash tests, a crash test dummy is buckled into the booster, which is secured to a sled, to simulate the forces experienced in an actual crash. This dummy has sensors in the head and chest that record the force exerted on those areas during testing. NHTSA crash studies show that the risk of injury is higher for forward-facing children. Head Injury Criteria (HIC) score is the factor used in the federal safety standards. This sensor data is a measurable way to assess the likelihood of injury arising from an impact. Better performance yields lower scores because the force exerted on the child is lower (lower numbers are better, like in golf). The Nuna aace had the most impressive results, with the lowest recorded sensor data in our commissioned tests. The Cybex Solution G2 achieved the second-best result, but it can't touch the aace. The Peg Perego Viaggio Shuttle Plus 120 had a similar result to the Cybex. The highest recorded sensor data for the most G-forces was found in the Safety 1st Grand 2-in-1; higher values are worse, as they indicate more G-forces when the goal is fewer. The Safety 1st result is more than double that of the Nuna acce.

Understanding the Chest (G) Clip Score


The test dummies include sensors that measure impact forces in the chest. The results from the chest sensors are used to calculate the Chest (G) score, which attempts to numerically estimate the likelihood of injury to organs in the chest cavity. The best chest clip scores for the group were earned by the Nuna aace and Nuna Lumn, with the lowest (and same) recorded g-force in our booster testing. The next-best results were obtained by the Peg Perego Viaggio Flex 120, followed closely by the Peg Perego Viaggio Shuttle Plus 120, UPPAbaby Alta v2, Clek Oobr, and the Cybex Solution G2.


High Backed vs. Backless


We prefer a booster with a back instead of a backless option because we believe they are intrinsically safer. Studies indicate that a high back booster can result in lower odds of injury compared to a seatbelt or a backless booster.

Comparing these injury risks to those of children restrained in seat belts, the adjusted odds of injury were 70% lower for children in high back belt positioning booster seats (OR=0.30, 95% CI=0.13–0.68), while the adjusted odds of injury were not statistically different for children in backless belt positioning booster seats (OR=1.17, 95% CI=0.40–3.43).

While there are no agreed-upon safety tests for side-impact collisions or other kinds of crashes to prove this theory definitively, we feel it makes logical sense that a protective shell (similar to that found on a convertible car seat) will provide additional protection for little ones, depending on the type of crash and the possibility of the intrusion of foreign objects into the passenger area. The difference is evident in both the crash test videos and in examining the actual sensor readings from the crash test dummy.



Additionally, a high-backed booster seat is more effective at keeping children positioned correctly, especially if they frequently nap in the car. A backless booster doesn't provide the support needed to keep little ones properly positioned if they fall asleep and slump or lean forward or to the side. We believe this theory makes sense, which is why we recommend using a booster seat with a back whenever possible. However, we believe that any belt-positioning booster is safer than not using a booster at all.

Best Booster Based on Crash Test Analysis


We rank each product against the competition based on an analysis of crash test reports, using a 1-10 scale.


This scoring method guides our assessment of products we believe offer an additional margin of protectionbeyond the basic level of protection found in every other seat on the market (as outlined by US Federal guidelines). The best crash test score in the group and the best combined sensor data in the test group belong to the Nuna aace. The Nuna Lumn follows just behind it. The Peg Perego Viaggio Flex 120 and Peg Perego Viaggio Shuttle Plus 120 come in third place, followed by the Cybex Solution G2, Clek Oobr, UPPAbaby Alta v2, and then the Chicco KidFit Zip Air Plus 2-in-1. We believe that the crash test details indicate that these higher-scoring options potentially offer an additional margin of protection compared to the average seat.

Ease of Use


Booster seats seem relatively straightforward and virtually the same. Some parents might even be tempted to forgo them (Do not do this!) However, they differ significantly in terms of ease of use.

This metric includes buckling, attachment, reclining, and additional features. Booster seats aren't as convoluted as convertible or infant car seats, but that doesn't mean they are universally easy to use. For this type of gear, one of the most important regular activities is buckling in, and whether little ones can do it themselves. Other ease-of-use features include attaching the seat to the vehicle (if applicable), adjusting the headrest and recline, and relocating the booster.

Shoulder Belt Placement


The primary goal of a booster seat is to position the vehicle's seat belt correctly to restrain a child during an accident. This placement is essential to provide the maximum possible protection. The shoulder belt pathway helps ensure the belt stays in the correct position in relation to your child. The best options thread easily and have adjustability to help ensure the belt is where it needs to be for children of different heights and shapes.


The easiest options for adjustment and placement were the UPPAbaby Alta v2, the Cybex Solution G2, and the two Peg Perego seats. The clear pathway does not require snaking it through a convoluted path, keeping the belt contained. The adjustable height ensures the belt is correctly positioned on the shoulder and across the lap. The most challenging were the Evenflo Maestro Sport 2-in-1 and the Safety 1st Grand 2-in-1, as they were not adjustable enough, and getting the placement right for every height proved to be a struggle.

Ease of Buckling


The ease of buckling a child into the booster should be simple for parents and the passenger. Booster-age kids are often able to do it themselves, and many prefer it; after all, they're not babies anymore. This makes it crucial that the task can be done without parental assistance and without an emotional breakdown that can come from challenging independent tasks.

The easiest for kids to buckle themselves in were, once again, the two Peg Perego seats and the UPPAbaby Alta v2. The two Peg seats have narrower seat bottoms, making it easier to access the vehicle buckle insert. The Alta v2 requires pushing the seat as far to the side as possible, away from the buckle, before sitting down. Once you do, the narrow width provides open access to make the connection. The hardest one is the Nuna Lumn. The distance from the seating area to the buckle is long and likely not easy to do for younger children. We suspect most parents will need to continue making this connection for little kids longer than they would with the average booster.

Ease of Installation


Many boosters just sit on the seat, with no installation required. The vehicle belt or potential LATCH connectors do the heavy lifting. They aren't like convertible car seats that need the right angles and sufficient tightness to create the safest possible situation. For this reason, the easiest are those that require nothing more than sitting in them and buckling up for installation. Next are those with a LATCH connection to prevent the seat from becoming a projectile. Most of these are similar, but those with rigid LATCH are the easiest because there is nothing to tighten. The Nuna Lumn is probably the hardest to install, but only in convertible car seat mode because it mimics that kind of more involved process. When used as a booster, it is less convoluted.

Overall Booster Ease of Use


Overall, ease of use encompasses the daily considerations and functionality that make using a booster a non-issue or a point of chronic frustration.


During testing, the UPPAbaby Alta v2 proved to be the easiest booster to use. With straightforward, rigid LATCH installation and easy-to-use adjustment features, this booster does what it's supposed to do without a problem. Following closely are the Peg Perego Viaggio Flex 120 and the Peg Perego Viaggio Shuttle Plus 120, both of which offer easy-to-use seat adjustments that go beyond the competition to create seating suitable for most children. This was followed closely by the Cybex Solution G2, Chicco KidFit Zip Air Plus 2-in-1, Chicco KidFit ClearTex Plus 2-in-1, Nuna AACE, and the BubbleBum. All of these options offer features that are easy for both parents and kids to use, as well as straightforward installation methods. The hardest-to-use boosters are the Clek Oobr, Evenflo Maestro Sport 2-in-1, and the Safety 1st Grand 2-in-1. The Nuna Lumn is also a standout for being harder to use; while not the worst, for the higher price, it feels more egregious.

Weight/Size


We checked the weight and width of each seat at its widest point. The booster's weight can be crucial if you use it for travel or carpooling.


Transporting the seat easily from car to car is essential if you plan to do it regularly. Also, the booster's width can be a factor in your decision if you need to fit multiple safety seats across your vehicle's back seat.


A narrower width could enable the installation of three safety seats across for multiple children. However, if your seat won't move cars often and you don't have a space limitation, weight and size are probably less crucial for your family.

Another consideration is that some high-backed boosters can be used without the back, creating a much lighter and smaller package that doubles as a travel accessory when the back is removed.

The BubbleBum booster can't be beat if your goal is compact and lightweight. This inflatable option rolls up and fits into its own stuff sack, which can be stowed in almost any backpack or carry-on. It weighs under a pound, and kids can carry it themselves. The Hiccapop has a similar design, but didn't perform as well in our crash tests. The top-scoring high-backed booster is the Safety 1st Grand 2-in-1, but it is not an impressive seat nor one we'd recommend to a friend. The Chicco KidFit Zip Air Plus 2-in-1 is relatively lightweight with the back in place, but can also be used without the back for those occasional carpooling or traveling adventures where a smaller seat is better. The Chicco Kidfit is even lighter by a pound over the Zip Air version with the leg rest. The Cybex Solution G2 is slightly heavier, but it is narrower than the Chicco options by at least an inch. The lowest-scoring option is the Britax Grow With You ClickTight+ because it is both heavy and large, weighing over 26 lbs and measuring 21.5 in wide. The Nuna Lumn is also a beast at 26.2 lbs, but it is slender at the base, measuring only 16.8 inches, with a width of 19 inches at its widest point.

Comfort


For comfort, we compare the foam support, fabric feel, seat design, seat bottom depth, headrest, and the potential for napping. Some boosters offer denser padding, a cushy feel, softer fabric, or a steel frame. Boosters are tested side by side by adult testers and children for general comfort compared to the competition. After all, who knows booster comfort best? Kids.

The Peg Perego Viaggio Flex 120 and the Nuna aace earned the top scores for comfort in our tests. They both feature adjustable headrests and back heights, but the Peg has adjustable side wings for added comfort and to ensure a better fit for kids of different sizes. It also features supportive padding and a headrest that provides a comfortable napping design.

There are several adjustments on the Peg that can make it more comfortable for kids of different sizes and needs.   Credit: Abriah Wofford

The Cybex Solution G2, Peg Perego Viaggio Shuttle Plus 120, Nuna Lumn, Chicco KidFit Zip Air Plus 2-in-1, and the Maxi-Cosi RoadiSport come next for comfort. The Chicco includes an optional leg lounge cushion for support of shorter legs. The Lumn also sports a leg rest to prevent legs from dangling. The Graco TurboBooster Backless and the Clek Oobr are the most uncomfortable options. The lack of a back and napping headrest hurt the score for the backless options (Graco TurboBooster, Hiccapop, and the BubbleBum), as none offered suitable padding that was supportive or a headrest for napping, leaving kids leaning or curled up in a way where the shoulder belt would not be appropriately positioned for safety.

Fabric Choices
The Chicco KidFit ClearTex Plus 2-in-1, the KidFit version without the leg rest, is available in various fabric choices, including one that zips off for easy cleaning. So, the fabric's softness or comfort may vary depending on your choice.

It is noteworthy here that our kid tester wasn't a fan of many of the seats and described more than one as being a “Rock with a blanket over it.” We considered this in our scoring, but it might not reflect how you'd expect. Because many of the seats have a hard plastic seating area and minimal padding, and our scores compare the seats side by side, not to an ideal imaginary seat, their scores may feel generous and possibly undeserving. Think of it like grading on a curve: if no one is that good, then no one is that bad either, and the final result could seem artificially high. That being said, if a booster scored remarkably low in this metric, you can bet it was an uncomfortable seat since none of the competition was that impressive.

Quality


For quality, we consider the materials and construction of the final seat. We analyzed the padding, foam, fabric, and attention to detail of our purchased competitors. Each component influences the booster's longevity and stability.


The highest scorers for the quality metric are the Nuna Lumn, Nuna acce, and the Britax Grow With You ClickTight+, followed closely by the Chicco KidFit Zip Air Plus 2-in-1, Chicco KidFit ClearTex Plus 2-in-1, Peg Perego Viaggio Shuttle Plus 120, and the Peg Perego Viaggio Flex 120. The Lumn is particularly a beautiful seat that screams luxury and money. It has leatherette accents and a streamlined design we didn't see in competitors. Nothing else is even remotely like it.


The lowest quality scores go to the Hiccapop UberBoost Inflatable Booster Car Seat and the BubbleBum. Both have a flimsy feel and use cheap, thin fabric, with the BubbleBum being ever so slightly better. The overall fit and finish look sloppy and somewhat incomplete, with stray threads and uneven stitching. However, the lower price tags make the quality level feel acceptable, even if it is disappointing. Additionally, quality is less of a concern since we view the BubbleBum as an occasional seat for travel or carpooling.

How to Pick the Best Booster Car Seat


Booster seats are an important part of your car travel safety journey. They are not a type of gear to skip or a safety seat you can do without. Because booster seats help position little ones properly for vehicle seat belt use or can keep them retained in a 5-point harness for longer, we think it is good to consider what you need and how much you can afford to ensure they are as safe as possible when traveling in a car.

How and Where


Often, when your child reaches booster age, they are on the go, participating in carpools or camps. This can mean a lighter-weight or more portable booster is necessary or preferred. Alternatively, your booster might live in one car, and your travel needs will be infrequent. Deciding how and where you will use your booster can help you divide contenders between heavy, substantial seats and more portable, smaller seats to prevent future frustrations. It might be that using two seats is the right solution for your family: one for everyday use and a second for travel or carpooling. Often, it is the only way to meet all of your needs. Many of the travel-friendly options are also relatively inexpensive, making two a potential solution.

Consider Safety


For our review, we commissioned independent crash testing on all safety seats. While installing and using your booster seat is key to creating a safer environment, crash test results can also help guide you toward options that may offer an additional margin of safety. You should consider which seats performed the best and how the results work with the size and type of booster that will best meet your needs.

What to Spend


As with all other safety-related gear, we think this is not the time to let money drive your decision. While we understand you need to stick to what you can afford, we encourage you not to go for the cheapest option; instead, look for the best option within your budget and focus on saving money on other gear.

Other Notable Booster Seats


Not all boosters make our selection cut, but that doesn't mean they aren't worthy of consideration.

  • Graco TurboBooster 2.0 LX — This is a high-backed version of the Turbobooster we tested. This budget-friendly booster has LATCH containment, a cup holder, and a snack tray.

Conclusion


Selecting a safe booster seat is just as critical as selecting other car safety seats. It is the final safety seat your child will use before transitioning to a vehicle seat unassisted, so your search for the perfect car seat is almost over. However, it is as vital as their infant car seat (you likely agonized over) to provide much-needed protection until they are tall enough to ride safely without a special safety seat. Therefore, we encourage you to carefully consider which booster to select. The details we provide will help you narrow your options to find the right booster for your family and budget. Before you know it, they will be tall enough to go sans safety seat and well on their way to moody teens.
