Best Car Seat for 4 Year Old Preschooler

What is the best car seat for 4 year old?

Kids at the age of four years old almost outgrow the weight or height limit of the convertible car seats used rear-facing with height limit generally comes first.

At this time, you should transfer your car seat to the front facing. Both convertible and booster car seats are good to fit a 4 year old child in forward-facing mode.

Convertible car seats are usually suitable for kids between 22 and 65 lbs and the weight of most four year old kids is in this range. So convertible car seats undoubtedly offer the best and safest fit for a 4 year old.

If you have read the product description of booster seats, you’ll find that they require a minimum weight- commonly 40 lbs for use, or at least 4 years old, whichever comes first. That means the booster seat is suitable for 4 year old toddlers.

Actually, a convertible car seat is generally used in the 2nd stage and purchased before a booster, you can use it for your kids until they break the convertible car seat’s limitation to transfer to the next stage.

Cases to move the kids to a booster exist. For example, if you have several kids at different ages and want to use the convertible for the smaller or smallest one, a cheaper booster is worthy consideration anyway. 

4-Year-Old Weight & Height

Boys and Girls Kids Weight and Height by Age

The average weight for a 4-year-old is 34 pounds for girls and 36 pounds for boys, according to the World Health Organization. How tall is the average 4-year-old? The average height for a 4-year-old is 39.5 inches for girls and 40.3 inches for boys.

This data shows that the kids generally break through the height limit first before the weight limit. But you can always use a convertible car seat that grows with your kids from extended rear-facing use to long forward-facing, like the Graco Extend2Fit, which is our favorite.

Best Car Seats for 4 Year Old

If you plan on buying a car seat with a higher rear-facing weight limit then your best option is to read my reviews of the convertible and all-in-one car seats. Those in the other categories are better suited to small infants with a low weight limit with no exception in the infant car seats and the travel system.

KidsEmbrace

A good choice for children who like Marvel heroes, the KidsEmbrace is an affordable harness to a booster seat. It delivers a reasonable top weight and height limits up to 100 pounds and 57-inches, making it an ideal option to grow with your kids. It’s a pity that this car seat will face front only for riding and traveling. But for its Marvel hero-themed exterior and good protection, it is still worth your consideration.

If you’re looking for a great convertible car seat for 4-year-olds that can be also used rear-facing longer in their 2-year-age, the Graco Extend2Fit is the best choice you can consider. Its 50-lb weight limit and 5-inch extended length in the height position extend a longer time to use it for rear-facing.

But this does not mean it’s poorly performed in the forward-facing. As a convertible car seat, it’s still good for riding a kid up to 65 lb. with the forward-facing harness. 65-pound is the highest limitation of all convertible car seats that can not work as a booster. 

As a traditional car seat brand, Graco has a few years of experience and designed its baby car seats with great safety. So does the Graco Extend2Fit.

To help protect your child from all side – frontal, side, rear, and rollover crashes, the car seat feature Graco® ProtectPlus Engineered™ technique that covers the most rigorous crash tests, including the side-impact tested for occupant retention with the built-in 5-point harness system, rear-impact tested based on the European Rear-Impact Crash Pulse, and tests called Graco’s RollSafe™ testing standard based on the European rollover testing procedure. These crash tests, along with their basic performance that meets or exceeds the child restraint criteria for a frontal crash test under the US FMVSS 213, ensure your kids’ safety whatever cases they meet in the car.

The reinforced steel frame and solid structure not only add points to its performance in the crash tests but also ensure the car seat to have a long lifespan – up to 10 years since the manufacturer date. 

Bonus parts also include two cup holders that are good to keep your child’s snacks and drinks close at hand. It’s not inevitable that your child would dirt the seat pad with no intention if they eat and drink in the car seat. 

Luckily, the seat pad is made of fabric that is machine washable. You can easily take the seat pad off the car seat and throw it into the washing machine for clean and comfortable rides in the next. Some parents think the taking-off procedure is hard, while some do not. For me, I stand in the line of giving it a 5-star rating. It’s not difficult to take off and put on the seat pad after several times.

2. Chicco NextFit Zip

Chicco NextFit Zip Convertible Car Seat

Chicco NextFit Zip

This is an excellent safety seat if you’re looking for something that has more bite to satisfy parents who want to ride their kids facing back for a longer time. More than the 43-inch top height limit, it also offers a lot of premium features including a 9-position headrest and reclines, LockSure belt-locking system, DuoGuard EPS energy absorbing system, and the most important one – zip-off design. If you want value for money as well as solid protection and comfort, the Chicco NextFit Zip is a winner.

Chicco NextFit Zip is one of the best convertible car seats for 4-year-old toddlers. It provides two modes to accommodate your littles from small infants to big kids preschool. A 4-year-old child can theoretically sit in the car seat in the two modes – rear-facing or front-facing, as long as they don’t exceed the weight limit of 40 pounds and height limit of 43 inches when using the NextFit Zip in rear-facing mode.

Based on the average weight and height table reference for boys and girls at their 4 years age, they may not outgrow the Chicco NextFit Zip. 

But rear-facing is not applicable for big kids who grow a bit faster than their peers. It’s time to change the NextFit Zip from rear-facing to front-facing if your child is ready – heavy and high enough.

The 9-position reclines and 9-position headrest adjustment ensure the Chicco NextFit Zip convertible car seat to accommodate well with your growing child. You can always find a perfect position for the safest protection and most comfortable fit when your child grows to 4 years old, no matter their weight and height. 

It supports two methods for installation – LATCH and seat belt. To help the parents to install it correctly, the car seat comes with two features for additional accuracy – the SuperCinch LATCH tightener and LockSure seat belt-locking system. Both work well for a correct installation in all car types wherever you travel with the Chicco NextFit Zip.

The manufacturer designed the car seat with the safest protection into consideration, even though it’s the entry-level model from the company. It still features the protective DuoGuard that provides two layers of head and body protection with a deep rigid reinforced shell and EPS energy-absorbing foam. The high-strength steel frame adds points to its protection performance in the crash tests. 

As an entry-level model, the NextFit Zip is not 100% perfect, but we still think it’s a good choice of the best car seat for a 4-year-old for its overall performance.

Britax Marathon ClickTight Convertible Car Seat

Britax Marathon ClickTight

Boasting a V-shaped tether and a high-strength steel frame for stable and reliable protection, a SafeCell technology for absorbing the crash energy, and the ClickTight for easy installation, it’s a great option for riding for 4 years old preschoolers facing forward. Even better, it has the reputation of a great brand behind it who are known for their innovation and thorough safety features.

The Britax Marathon can accommodate a 4-year-old child in front facing. It’s suitable for kids between 5-65 lbs in weight and up to 49-inch in height, making the Marathon a good car seat for 4 years old toddlers

The Marathon is a typical Britax car seat, coming with a few advanced features to keep your child safe and comfortable in the seat. 

Let’s start with Britax’s exclusive functions like the SafeCell technology, V-Shaped tether, and high-strength steel frame. The SafeCell technique crumpled-body can efficiently absorb the crash energy while the V-shaped tether makes the car seat more stable, slow the movement, and twists in a crash. These two unique features help a lot reduce the risks in case of any crashes. A mom commented about the Marathon’s safest protection for her littles in a crash.

The steel frame provides the car seat a strong power for solid and stable protection, but it also results in a bulky body. But we can’t complain about it, as most convertible and booster seats on the market feature a bulky body.

The Marathon car seat is designed to grow with your child, thanks to its 14-position headrest and harness adjustment and 7-position reclines. That means, you can always find a perfect position to fit your child with the safest protection while getting the most comfort in the car seat.

The ClickTight feature enables the parents to install the car seat with ease. But you should always keep an eye on the tightness between the straps/harness and your child’s clothes. Putting your child too tight may cause an uncomfortable fit, you should leave at least one finger’s gap.

We mentioned this because many parents on Amazon complain about the Marathon’s tightness and can’t easily loosen for a better fit, especially for big kids. The company designed the Marathon to be used in front facing for children from 5-65 lbs, but if it’s not correctly installed and buckled, you’ll feel it too tight for big kids in the car seat with a 5-point harness.

Anyway, if you have any questions about the car seat, you should contact the company for support in time, or find another alternative.

Safety 1st Jive

Safety 1st Jive Convertible Car Seat

Safety 1st Jive

The Safety 1st Jive is an excellent budget safety seat that’s a great match for a 4-year-old preschooler because of the wide weight and height range (5-65 pounds and 19-49 inches). It’ll give the child good protection without having the parents break the bank. Multiple colors are available for boys and girls. Approved for aircraft use, along with a lightweight body, it’s very portable and friendly for families that prefer a traveling lifestyle.

Safety 1st Jive is the fourth recommendation of the best convertible car seat for 4-year-olds. It’s designed to grow with your child from newborns until they exceed its highest weight limit of up to 65 pounds, generally for kids of 7-8 years old at average or big and tall kids at 6-7 years. So it absolutely fits your child when they’re 4 years old.

Safety 1st Jive allows your little one to stay rear-facing before they reach the 40-pound weight limit and at least 1-inch below the handle. After that, you should change it to forward-facing, removing the head and body pillows that provide extra support when they’re small. This gives your growing child more space to ride in front-facing.

Featuring a slim design, the Safety 1st Jive is ready to fly with your child on an aircraft. It’s approved for airplane use. But you should pay attention to its installation in the airplane to ensure your little one’s safety during the flight.

The slim design also makes it to well fit 3 across in the rear seat of most vehicles. If you ride a small car with narrow seats, you may install it for a try. Growing families with several toddlers can also give it a shot.

To cheer up your little one in the car seat, the Safety 1st Jive comes with 2 cup holders to carry the snacks and drinks, within their easy touch. The cup holders are removable for cleaning if they get dirty, which is inevitable for kids.

To save the parents’ energy and time, the Safety 1st Jive is made of machine washable and dryer-safe fabrics. You can easily take the seat pad off and throw it into the machine for cleaning.

Last but least, the Safety 1st Jive is a cheap option on our list, but you don’t need to worry about its safety rating. Safety 1st is also a great brand like Graco and Britax and earns an excellent reputation among the parents’ hearts.

KidsEmbrace is a very popular 2-in-1 harness booster seat for 4 years old children. All the car seats from KidsEmbrace come with the Marvel subject cover. Who does not like a Marvel Hero? The car seat provides two modes to fit a 4 years old child: a 5-point harness convertible and a belt-positioning booster

The KidsEmbrace is approved for forward-facing use in convertible mode. Just like all the other car seats used in this mode, it supports accommodating a child between 22-65 pounds with a 5-point harness that allows for at least 29-inch minimum height rating and at most 49-inch maximum height rating. Most kids at their 4 years age can fit well in this car seat with appropriate weight and height in the range. 

Parents should stick with the forward-facing harness until your child outgrows the harness height or weight limits, whenever comes first. Generally, the height limit is easier to reach. The KidsEmbrace is good enough to ride a 4-year-old child, no matter if they’re at an average weight/height or big kids that grow faster than their peers.

However, you should change it from a 5-point harness convertible model to the belt-positioning booster mode when your child exceeds the weight or height limits. Kids are safer to ride in the right car seat for their age, weight, and height. It’s risky to put a small baby or toddler in a booster; vice versa, it’s also dangerous to put a big kid in an infant or convertible car seat. 

The KidsEmbrace is suitable for kids between 40-100 lbs and 38”-57” in height in the belt-positioning booster mode, but no backless booster usage after that. 

The manufacturer provides a one-year limited warranty for major parts, no extended warranty is available.

Graco 4Ever DLX is one of the best all-in-one car seats for 4 years old children.

A 4-year-old child is theoretically able to use a booster in the car. Most boosters boast that their minimum weight limit is at least 40 pounds, and the minimum age requirement is 4 years old. When your child grows to 4 years of age, they’re ready to fit in a booster.

This does not mean you’re required to switch to a booster at their fourth birthday. Actually, it’s safer for the kids to stay in the five-point harness as long as possible before the kids grow out of their convertible car seat’s high weight limit of 65 pounds. 

Graco 4Ever DLX 4-in-1 can work as a convertible child seat to keep your child safe from 2 years to 8 years. The 10-position headrest is designed to grow with your child and protect their head and neck in case of any crashes. The harness is also good to avoid any big move or hit in the car seat for emergency stop or crash. That’s why your child should sit in the five-point harness forward-facing until they outgrow the 65-lb.

Graco 4Ever DLX all-in-one can be used as a booster to accommodate your growing child, with an upper weight limit of 100 pounds for highback booster and 120 pounds for backless booster. You need to store the harness and use the seat belt to install the car seat in booster mode. 

Graco 4Ever DLX is an upgraded version over the 4Ever, with a few great improvements. Let’s see what’s the difference between the 4Ever DLX and 4Ever.

Graco 4Ever DLX 4-in-1 vs 4Ever 4-in-1

The 4Ever DLX 4-in-1 features the ProtectPlus Engineered that is used in many new Graco products to provide better safety protection by passing through more rigorous crash tests from all sides – frontal, side (for 5-point harness), rear, and rollover. 

The Graco 4Ever DLX 4-in-1 is designed with more convenient harness storage compartments to store the harness when it’s not in use.

There is an integrated belt lock-off function in the upgraded Graco 4Ever 4-in-1 car seat, ensuring an easier and more secure installation. 

Both 4Ever DLX 4-in-1 and 4Ever 4-in-1 allow removal of the seat pad for machine washing. But the upgraded DLX version is much easier and needs less effort to take the seat pad and cover off and put it on, thanks to the new Rapid Remove trick – the seat cover is divided into several parts that are connected with the snaps for easy taking off and putting back.

The ability to go through 3 stages makes it an ideal option if you’re looking for a budget money saver. It’s the cheapest all-in-one car seat you can find on the market. Not to mention, it’s narrow width to fit 3 across for big families – who’s not like it?

The Diono Radian 3R is a good booster seat for a 4 year old after they outgrow the weight or height limit in the rear-facing mode. It combines three modes into one – rear-facing harness, forward-facing harness, and highback booster, lacking the backless mode as the backrest is not detachable. 

But this does not affect the Radian 3R’s performance to fit both newborns and teens. It highlights a 5-lb rear-facing lower weight limit for newborn babies, and up to 120-lb highest weight limit for teens around 12 years old. 

When your child is at 4 years of age, you may put them in the harness convertible mode or the booster mode if they reach the minimum 40-lb weight in a booster. However, it’s recommended to stick with the forward-facing harness mode until your child outgrows the harness height or weight limits. The longer your child stays in the current and appropriate stage, the better and safer he or she is. 

The Radian 3R is made from automotive-grade high-strength steel to shield and protect your child in the car seat. The mechanically engineered and reinforced steel core ensures it lasts for the promised 10 years lifespan. 

It’s not surprising that the Radian 3R is designed with long-lasting usage. Almost all the 3-in-1, 4-in-1, or all-in-one car seats have a lifespan of 10 years. After all, they’re developed to grow with your child from their birth until they’re big enough to use the car’s seat belt for security. 

Last but not least, the Radian 3R is a great choice for big families with several children. It’s designed to fit 3 across, meaning that you can install three Radian 3R in the back seat at the same time. You don’t need to worry about the compatibility of installing multiple car seats in the rear now, especially when you have a twin and another older or younger baby.

However, you must know that the Radian 3R is not 100% perfect. It’s bulky, even featuring a clean and foldable design. Most multifunctional car seats are bulky and heavy. The attachable stand looks very cheap and less reliable than other car seats’ one-piece design.

Anyway, the Diono Radian 3R is worth its price in the overall performance and most importantly, it’s a good money saver.

The Maxi-Cosi Pria provides two modes to ride a 4 year old child – harness convertible and booster, while the latter requires your kid to weigh at least 40 pounds. That means if your child is less than 40 pounds in weight, you should not locate them in the booster. This is quite in accordance with the experts who suggest that parents should stick with a forward-facing harness until their child grows to excel at the harness height or weight limits. 

When using the convertible model, the Maxi-Cosi Pria supports kids weighing from 22 pounds to 65 pounds. This weight range enables the car seat to accommodate children of 4 years old well, or even when they’re 8 or 9 years old before switching to the booster mode. 

The Maxi-Cosi Pria is pricey, the looked high-quality cushion attributed a lot for that, not the feature to ride a kid in three modes. There are a lot of all-in-oine car seats on the market sold at a cheaper price. But Pria is still worth your consideration if you have enough budget for a best car seat option for a 4 years old. 

It provides a 3-position recline, allowing the parents to correctly install the car seat on the right stage. The 5 headrest heights, along with a quick fit shoulder harness, ensures your child has a most comfortable and appropriate fit in the car seat.

Thick stuffing looks better than safety? It’s not true but a good selling point that the company boasts of. The Maxi-Cosi Pria is designed with cell-side impact protection built into the headrest to cushion the impact. The supreme soft-to-touch cushions and premium fabrics and padding throughout provide the best comfort for your child during the trips. 

Parents don’t need to worry about the car seat getting dirty. The covers are easy to remove and machine washable and dryer safe. It’s easy for the parents to keep the kids comfortable and cozy in the Maxi-Cosi Pria 3-in-1 car seat.

Graco SlimFit3 LX is one of the 3-in-1 booster car seats for 4 year olds. It is designed to grow with your child from a rear-facing harness (5-40 lb) to a forward-facing harness (22-65 lb) to a highback booster (40-100 lb).

To fit your 4-year-old child in the Graco SlimFit3 LX, you need to install it in front-facing and use the 5-point harness to accommodate them for protection. 4 years old kids have generally outgrown their rear-facing car seats but did not reach the minimum requirements in a booster, which requires a child to be at least 40 pounds in weight or 43 inches in height or over 4 years old.

When being used in the five-point harness convertible mode, the Graco SlimFit3 LX is suitable for kids weighing between 22- 65 pounds. It’s obvious that the 4-year-old children can adapt well in the seat. The 10 positions headrest allows you to choose an appropriate headrest and harness height to get the safest fit for your child when they grow to 4 years old. It also features the Gracon’s classic No-Rethread Simple Safe Adjust Harness System and you can adjust the headrest and harness together in one motion to get a perfect position.

Graco SlimFit3 LX ranks as a top option in the best car seats for 4 years old for its slim design, just as its name indicates. Thanks to its unique rotatable cup holders, it’s 10% slimmer than other Graco car seats. This saves a little space in the rear back seat, very precious for small cars and big families. It’s one of the best car seats for 4 year old that fit 3 across, meaning you can install up to 3 car seats in the vehicle.

It’s also ProtectPlus Engineered to pass through the most rigorous tests frontal, side, rear, and rollover crashes, providing the safest protection to your littles in the car seat. But it only allows 4-position reclines to adjust for your kids, less than the Extend2Fit and 4Ever DLX’s 6-position reclines.

Best Car Seat for 4 Year Old Toddlers

Graco 4Ever DLX – Fear facing, forward facing, high back booster, backless booster

Chicco NextFit Zip – up to 43-inch for rear-facing riding for a longer time.

Diono Radian 3R – Narrow 17-inch width to do 3 accross fit for big families

Maxi-Cosi Pria – Plenty of padding for comfort and safety.

Best Car Seat for 4 Year Old Toddlers

A four-year-old can sit in a convertible or booster. If you have purchased a convertible for use, just stick with it until your child outgrows the harness height or weight limits. If you need to buy a new car seat for a 4 year old, the booster is a cheaper option. It’s better if you weigh over 40 pounds to ride in a booster seat.

Yes, booster car seats are safe to ride for 4 years old children. The highback booster is better than backless booster because the former gives your child additional head and back support.

But it’s better for them to sit in a convertible seat with a harness for fit and protection. Choosing a convertible or booster depends on your personal needs.
