When do kids switch to booster seats? When they reach the top height or weight limit of the 5-point harness forward-facing – 65 pounds or 49 inches, it’s time to move the kids to a booster seat. If you have used a convertible car seat that can support booster mode, it’s okay for you to still use that seat. But if not, you need to shop for the best booster car seats for your kid at this time.
Booster seats are designed to ride your child safely before they can use the vehicle seat belt alone as a grown-up. They can help raise the kids up so that you can position the vehicle’s safety belt properly on your child through the shoulder and lap, providing maximum protection to your child’s neck and chest in case of any accidents.
However, booster seats should be used when your child is ready for that. It’s not recommended to move them to a booster seat too early and keep your child in a 5-point harness car seat for as long as possible. Ask yourself below four questions before transitioning your child to a booster seat:
> Is your child at least 5 years old?
> Is your child at least 40 pounds?
> Are the shoulder and lap belts available?
> Can your child sit properly the entire trip without leaning forward, slouching, playing with the shoulder belt, etc?
If you can answer “Yes” to all the questions, your child is safe to use booster seats and you can shop for one now.
But first, you should know which booster seat is the best option for your child. The most commonly asked question I received from many parents is what’s the age requirements for using the booster seats. As the demands that parents want to put 3 year olds or 4 year olds in a booster (laws require kids to be at least 4 years old to use a booster seat), a new type of booster comes into the market – harnessed booster. So I’ll add this into consideration when creating this best booster seat buying guide.

#1 Best Booster Seat for 6-8 Years Old
Graco TurboBooster
Key Features
- Weight range (lb): 40-100
- Height limits: 43~57"
- Stage: 3rd
- Lifespan: 10 years
- Suitable: 4-9 years old
The Good
- Super budget price

$28.99
Graco TurboBooster backless is one of the two booster seats under $30. It’s no surprise that it becomes one of the most popular car seats on Amazon, receiving over 40,000 reviews from hundreds of thousands of parents. It’s the best choice to step next when the kid grows out of their convertible car seat.
The best budget price does not compromise the performance. Like all other booster seats, it is able to accommodate a child with the minimum requirements: 4 years old, 40 pounds, or 43 inches tall. Even though you won’t switch to the Graco TurboBooster so early, it’s good to see these booster seat requirements are as low as other expensive models. The upper size limit of 100 lbs/57″ is as good as the more priced booster seats as well, making Graco TurboBooster a good car seat for 5 year olds to 7 years of age.
Graco TurboBooster is lightweight, low profile, and slim fit, making it friendly for traveling. It’s also a good thing to note that if you want to save space in the back seat or plan to install multiple car seats in the same row, the Graco TurboBooster is only 16.25 inches wide. Big kids around 5 years or older can easily get in this seat and buckle themselves. What you need to do is to confirm the seat belt (used for installing a booster) is placed correctly.

Chicco GoFit
Key Features
- Weight range (lb): 40-110
- Height limits: 38~57"
- Stage: 3rd
- Lifespan: 8 years
- Suitable: 4-9 years old
The Good
- Easy to carry
- Ultra-comfortable
The Bad
- Slip easily
- No LATCH connection
$49.99
If you have a $20 more budget for a backless booster seat, you may choose the Chicco GoFit, which is around $20 more expensive than the Graco TurboBooster. But you’ll find it’s worth it if you like a booster seat with a higher weight limit or convenience.
The Chicco GoFit has a higher capacity: 110 pounds vs 100 pounds of Graco TurboBooster and Cosco Topside. This makes a slight difference because the upper booster height limit is the same, all at 57″. (this is the minimum booster height requirement for a kid to stop using a booster seat.) The 110-pound weight limit only means that the Chicco GoFit is better for heavier kids.
It weighs very similarly to the Graco TurboBooster, about 5 pounds. But what makes it more appealing for both parents and kids is the built-in carry handle in the Chicco GoFit. The carry handle is located at the back of the seat near the armrest and the kids can carry this lightweight booster seat themselves when they travel in different cars.
The Chicco GoFit has two siblings- GoFit Plus and GoFit with ClearTex No Chemicals. Both are several dollars more expensive than the GoFit basic version. The GoFit Plus has a Quick-Release LATCH for easier installation while the ClearTex version has fewer chemical emissions.

#1 Best Booster Seat for 4-5 Years Old
Graco Affix
Key Features
- Weight range (lb):40-100
- Height limits: ~57"
- Stage: 3rd
- Lifespan: 10 years
- Suitable: 4 to 9 years old
The Good
- High-back for optimal protection

The Bad
- Limited padding

$89.99
If you’re finding a booster seat that can fit very well in small cars, the Graco Affix is worthy of your consideration. Featuring a compact design with dimensions of 15.5 (D) x 16.5 (W) x 26.8 (H) inches, the Affix booster seat can even fit three-across well and is also a great option for growing families.
The Affix booster seat helps safely transport toddlers and young kids aged from 4 to 10 years old and weighs from 40 to 100 lbs, and is up to 57 inches tall. The company upgrades the age and weight requirement due to the NHTSA’s newest safety standards for booster seats – at least 4 years old or 40 pounds or more.
The Graco Affix High-back booster seat comes with a front-adjust LATCH system, which provides a secure connection between the car seat and vehicle and allows your child to easily buckle themselves with the seat belt. Please note that this LATCH system is just used for securing the booster seat to the vehicle, a bit different from the convertible car seat LATCH for installation.
It offers great convenience for both your child and you. The seat has an integrated cup holder and hide-away storage compartment to keep the child’s drinks and favorite things within arm’s reach. The seat cushion is made of machine-washable fabric for easy cleaning, and the metal and plastic parts may be simply cleaned with mild soap and cool water.
The good:
The Graco Affix Youth booster seat features a compact and lightweight design, making it the best option for small cars and growing families.
Combining high-back booster mode and backless booster mode into one car seat, the Affix Youth can be used longer for growing children, along with a 10 years lifespan. Thanks to the LATCH system, the Affix Youth booster seat allows for easy security, and even supports self-buckling by your child.
The not good:
This booster seat is not that perfect for big kids, even its description has a statement for “big kids”. Its weight limit is only up to 100 pounds, much lower than Britax Skyline’s 120 lbs weight limit.

Graco Tranzitions-Best Booster Seat for 3 Year Olds
Graco Tranzitions
Key Features
- Weight range (lb): 22-65 (FF); 40-100 (Booster)
- Height limits: 49" (FF); 57” (Booster)
- Stage: 2nd, 3rd
- Lifespan: 7 years
The Good
- Budget price
- Up to 100 lb weight limit for big kids
- Three modes: harness, high back, and backless
- Graco ProtectPlus Engineered for optimal protection
The Bad
- Not fit 3-across
$139.99
If you want a booster seat for toddlers as young as 2 years old, then you won’t miss the Graco Tranzitions. It should be our best recommendation for its performance and its price.
Don’t let the price of the Graco Tranzitions 3-in-1 harness booster make you think you think you’re missing out. It’s a booster over $100, however, it’s worth it. The 3-in-1 design means it can be used in three different modes: forward-facing, high-back booster, and as a backless booster seat. (It’s the only booster seat with 5 point harness on the market with this three-mode functionality.)
With a weight requirement as low as 22 pounds, the Graco Tranzitions 3-in-1 is a good booster seat for 2 year olds. And you should use the 5-point harness for small toddlers before they are 40 pounds or 4 years old. Of course, it’s better to keep a kid in the 5-point harness for as long as possible until they reach the upper height or weight limit – 65 lbs/ 49″. That means, it is a good car seat option for 4 year olds, with 5-point harness protection in forward-facing mode.
The Graco Tranzitions 3-in-1 booster seat is forward-facing only – lacking rear-facing mode for newborns and small infants. So it’s a good choice for the next step after the kids grow out of their infant car seats. Let’s explain this with a second, the minimum weight requirement of Graco Tranzitions (22 pounds) is less than the upper weight limit of infant car seats (30 or 35 pounds).
That means, your kids should be good to fit in Graco Tranzitions when they are 30 or 35 pounds. However, some states, like New York, Virginia, Washington, etc, require a kid to stay rear-facing until 2 years old. If this is your case, you’ll need a rear-facing car seat for toddlers.
Different from most 2-in-1 harnessed booster seats like the Graco Atlas and KidsEmbrace SpiderMan, the Graco Tranzitions car seat comes equipped with a backless design. This saves money because you don’t need to spend at least $20 to buy a backless booster. The no-back booster from Graco Tranzitions is very similar to a real backless booster – low profile and lightweight. That’s better than the backless mode from Graco 4Ever DLX. The latter is very thick, retaining the seat pad from the previous three modes.

- Stage: 3rd
- Lifespan: 8 years
The Good
- Up to 100 lb weight limit for big kids

$109.99
If you’re looking for a booster seat that can provide your child the most comfort in the car while saving you the most effort to wash it, give Chicco KidFit a try. The ergonomic designed double foam padding and contoured seat pad allow riding your child extremely comfortable on any trip. The seat pad, cushions, and armrest covers are machine washable, not just costing less time for convenient cleaning, but also offering a neat space for your child.
As its name states, the Chicco KidFit is a 2-in-1 booster seat that can be used as a belt-positioning high-back booster seat for children from 40 to 100 pounds and converted to a backless booster seat for children from 40 to 110 pounds. It’s a good car seat for big kids 5 years or older.
The Chicco KidFit 2-in-1 comes with a detachable design so that you can easily change it from high-back booster mode to backless booster mode as your child grows – just remove the backrest. The backrest supports 2-position adjustment to provide growing children with a snug and secure fit.
The Chicco KidFit is as safe as other Chicco car seats. The easy-to-use vehicle belt guides allow you to effortlessly position the vehicle seat belt for proper installation. The equipped premium LATCH connectors, along with the SuperCinch one-pull tightener, stabilize the seat and keep it secured when your child is on it. The 10-position headrest is made of EPS energy-absorbing foam for extra impact protection and can be adjusted for protecting your growing child.
On both sides of the Chicco KidFit booster seat, there are two cup holders to keep your child’s drinks, snacks, and favorite toys within reach. They’re removable and foldable to save space between seats if you want to install two or more seats in the back seat. Make sure you measure your vehicle seat width before installing multiple seats in the car, as the Chicco KidFit is not designed for fitting three across.
The good:
The ergonomic designed double foam padding seat provides better comfort to your child to stay in the car, especially great for long-distance travel. Made of machine-washable fabric, the Chicco KidFit is very appealing for parents who don’t want to hand wash a messy car seat. When used as a backless booster seat, the Chicco Kidfit allows a weight limit of up to 110 pounds, better for larger kids than other seats’ 100 pounds limitation.
The not good:
This car seat is a “real” booster seat, not supporting to hold a smaller child with a harness.
Best Booster Seat for 4 to 10 Years Old
Britax Skyline
Key Features
- Weight Range (lb.): 40-120 (high-back); 48-120 (backless)
- Height Limit: ~63"
- Lifespan: 9 years
- Type: Booster
- Stage: 3rd
- Suitable for: 4-10 yeas old
The Good
- Budget price
- Two modes - high back & backless
- Lightweight and slim to do 3 across
The Bad
- Limited padding
- Not machine washable
$109.99
If you’re finding the best booster seat from Britax, the Skyline is a good consideration. It’s very easy to install and use. This booster seat comes with a 10-position headrest to ride 4-year-olds until they reach the top 120 lbs weight limit, generally in their 9-10 year ages.
When used in booster mode, the Britax Skyline has a higher weight and height limit, from 40-120 pounds in weight and up to 63 inches in height, making this booster seat the best option for large and tall kids. It seems only Britax car seats (all-in-one and boosters) have this higher booster height limit than other car seats.
The Britax Skyline booster seat comes with a SafeCell safety system, including a steel frame, energy-absorbing base, and patented V-shaped tether, to provide better safety.
The impact-stabilizing steel frame offers superior strength at the connection point to the vehicle for the car seat’s stability. The V-shaped tether minimizes seat rotation and keeps your child stable by reducing forward movement during a crash. While the impact-absorbing base helps reduce the force of a collision. Plus, 2 layers of side impact protection provided by the deep energy-absorbing shell assures you that this car seat is safer for protection.
The Britax Skyline rides your child with the most comfort. The multi-position recline allows you to adjust the best angle for a snug fit for your child. While the quick-adjust, 10-position headrest allows you to easily move the harness upward for a comfortable, secure fit as your child grows. The integrated cup holders on both sides keep the drinks and snacks very close at hand, ensuring your child won’t feel hungry or thirsty during long-distance travel.
It’s a pity that the car seat cover is not machine washable, even though it states that the cover can be easily removed for hassle-free cleaning. Some parents choose to clean the cover with a machine that features a hand wash setting.
The good:
The Britax Skyline is a great booster seat for safety. The SafeCell system consisting of the frame, base, and V-shape tether ensures perfect protection, along with the 2 layers of side impact protection. The ClickTight technique allows parents to easily install the seat correctly. The broader range in weight (25-120 lbs.) and height (up to 63”) makes the Skyline the best choice for tall kids or allows a longer time in the belt-positioning booster seat.
The not good:
The back is not removable and the seat can’t be used as a backless booster for older children before they can use the vehicle’s seat belt. The design is a bit bulky and this car seat might not fit well in small cars.

When to Buy Booster Seats
When your child outgrows the weight or height limit of the forward-facing child safety seat with a harness, it’s time to convert to a booster seat. This generally happens during your child’s 4-5 ages, some big or tall kids may need a booster seat when they’re 3 years old because they reach the forward-facing seat limitations faster.
However, it’s not recommended to rush to move your child to a booster seat before they’re ready. And the child safety experts suggest to keep your child in a harness seat as long as possible.
Of course, you need to prepare the booster seat before your child needs it. If you have use a combination seat that supports booster mode, like all-in-one convertible seats, you don’t buy another booster seat anyway, just remove the harness and transition it to booster mode.
Things to Consider to Look for the Best Booster Seats
> Your child. You should always take your child’s weight and height into consideration before picking up an appropriate booster seat, after all, it’s them who stay in the car seat for a long time. Your child’s age is a useful reference, some booster car seats state their age requirements, like 2 years or 4 years old. If your child grows faster and taller, you might need a booster seat that features a higher weight/height limit and is great for big kids.
> Your budget. The booster seats are priced in a wide range. Some have a cheap price under $100, even under $50; a few costs hundreds of dollars with premium materials and additional features. But you can always find a suitable and safe booster seat within your budget.
> Your vehicle. Even the booster seats are not as bulky as convertible car seats, they come with different sizes and design. Some booster seats feature a wide width may not fit well for compact cars, especially those boosters with two built-in cup holders on both sides, they may not even fit 3-across.
> Growing with your child. As your child grows, they may not want to stay in a car seats with backrest, a booster seat that can be used in high-back and backless modes are preferable at this time.
Types of Booster Seats
High-back Booster Car Seats
Also called Belt Positioning Boosters: Comparing with backless boosters, they have a back and head support which goes up past the child’s ears. They usually require a lower minimum weight limitation than backless booster, and can be used for smaller toddlers. Many of these models allow you to remove the back and turn the seat into a backless booster – this option is very helpful for travel and for storage. You can check our top-rated 5 boosters with back and backless list at the bottom.
Backless Boosters
These are specialized cushions for children to sit on. The booster raises the child up off the vehicle seat for a better seat belt fit. Backless boosters all have seat belt guides which keep the seat belt over the correct place on the child’s body. Sometimes armrests serve as the seat belt guides, other seats use metal tubes or rings.
Advantages of backless boosters: They are more lightweight, compact, and less expensive than a high-back booster seat. Making the children appear less “babyish”, they’re often preferred by older kids.
Belt-positioning Boosters with Harness
Featuring a similar design and belong to the high-back boosters, they function either as a car seat with a 5-point harness for children up to at least 40 pounds OR a belt-positioning booster for kids over 40 pounds. Transition from harness seat to a booster, you just simply remove the harness and use the vehicle’s safety belt to secure the child. However, the back is usually not removable on these models.
Advantages of high-back boosters: they usually come with an adjustable headrest that gives the best positioning of the shoulder belt for easy installation. The included headrest also provides necessary head support in vehicles with low seat backs. They are also better than a backless booster at keeping a sleeping child placed properly in the safety belt.
Combination (3-in-1)
There are three kinds of combination seats: one is the high-back booster seats with 5-point harness to ride smaller toddlers; another is the high-back boosters with a detachable backrest that can be removed when your child is ready with no back support; and the last is the one that combines all three features into one – harness, high-back and backless.
Advantages of combination boosters: They can use for a longer time through your child’s toddler to the youth ages and saves money to buy multiple booster seats.
FAQs on Booster Seats
When can a child use a booster seat
You can always find the minimum weight and height limitations of a booster seat in its product description, 30 pounds or 40 pounds for most booster seats. Generally, if your child’s weight or height falls into the range, you can move him/her to the booster.
Some booster seats may also state an age requirement, like the Britax Pinnacle ClickTight for 2+ years toddlers and Clek Oobr for 4+ years kids.
It’s strongly recommended to keep your child in a harness seat as long as possible before moving them to a booster seat, even if their weight, height or age has reached the minimum requirements.
When can my child stop using a booster seat
The answer depends on your child’s size and age, and the law in your state. Laws aside, kids aren’t ready to switch from a booster seat to seat belts until they’re at least 4 feet 9 inches tall and can pass the five-step test below – typically between ages 8 and 10.
To judge whether your child is ready to ride with a seat belt alone, test the fit of your vehicle’s belts from time to time. Buckle your child into the back seat without a booster seat, and consider the following:
Does he sit all the way back against the car’s seat?
Do his knees bend comfortably at the edge of the seat?
Does the lap belt naturally rest below his belly, touching the top of his thighs?
Is the shoulder belt centered across his shoulder and chest?
Can he stay seated like this for the whole trip?
If you answer no to any of these questions, your child should still stay in the booster.
Do booster car seats expire?
The short answer is yes. All child safety seats have a life-span after they leave the factory where they are manufactured. Most manufacturer have stated an expiration date on the seat, or mold it onto the shell on the back of the seat, some even introduce on their official site. We also include the lifespan for most booster seats in our list. If you can’t find it online, you can call the customer service for help to check. The expiration date of most booster seats is six (6) years from the date of manufacturer, if it is not specifically announced.
Can a 3-year toddler use booster car seat?
That depends. Generally, when your child’s size (weight and height) meets the low requirements of a booster car seat, you can switch a booster seat for him/her. But it’s always recommended to keep your child in the last stage of forward-facing harness seat as long as possible. Or you can ride them in some booster seats with a 5-point harness, like the Chicco MyFit.
What is the law for booster seats?
That depends on the highway safety law of each state. Every US state has made the laws to require the driver or operator to ride the children with a child passenger safety restraint system, like a car seat or booster seat or travel vest. In most states, the child less than 57 inches in height are required to stay in a booster seat. This may vary based on each state’s specific requirements, and you can read the booster seat laws in the next part or our post on car seat laws to find the local of your state.
What is the safest booster seat on the market?
Actually, all the booster seats meet the federal safety standards and go through rigorous tests before it selling on the market. The safest seat is the one that fits your child’s age, weight, height and behavioral maturity, can be properly installed in your vehicle and will be used correctly every time the child rides in it.
How long do kids need booster seats?
The kids need booster seats until they reach 4 feet 9 inches. This typically happens when the kids aged between 8 and 12 years old. So a few US states also suggest the booster age requirement to be 8 years or older to get out of a booster seat.
If the kids start to use booster seats at 4 years or 5 years old, they will need to stay in the booster seats for three or four years long time.
What car has built in booster seats?
It’s not necessary to have built-in booster seats in the car because there are a lot of cheap booster seats on the market and you can customize the travel convenience based on your needs and budget. Right now, there is only Volvo that offers built-in booster seats. The car models include XC90 – with a single booster seat in the center of the second row; XC60 and V90 – with a pair of booster seats on the outboard seating positions of the second row.
How long are booster seats good for?
Booster seats have a lifespan between 7 and 10 years. That means they are good for at least 7 years of usage since the date of manufacture. The shortest 7 years is good enough to let the kids go through the last booster stage from 4 years old.
When do kids switch to booster seats?
It’s okay for kids to switch to booster seats as long as they’re at least 40 pounds or 4 years or older. However, it’s not recommended to switch to booster seats too soon. The best practice is to keep kids in a car seat with a 5-point harness for as long as possible until they outgrow the 5-point harness height or weight limit.
When do kids stop using booster seats?
According to the US car seat laws, kids can stop using booster seats when they’re 8 years old or reach 4 feet 9 inches (57″). Only at this height, the kids will be big enough to fit the seat belt correctly.
Check the booster seat laws to find the details.
