So, your child is four years old? What a fun age!

At four, children are developing confidence, whether it’s going down the slide by themselves, putting their shoes on, or giving us their strong opinion on why they should have ice cream for dinner.

As confidence builds, they grow, and they reach new milestones, and parents have to adapt to keep up, which means buying new clothes, more foods, and perhaps another car seat.

At four-years-old, children are growing quickly, so you want to make sure that the car seat you choose will accommodate the growth spurts. The best kinds of car seats for this purpose are booster seats or convertible seats that transform into booster seats.

Below are the best of the best car seats for your 4 year old in your family. If you need more education, see the helpful buying guide after the product reviews.

2. RideSafer Travel Vest: Wearable Booster Seat Alternative


As kids grow, their safety needs while traveling change a bit. By the time a child reaches four-years-old, he is usually ready for a booster seat. However, booster seats can be heavy and cumbersome, especially if you frequently travel and need to switch them to and from different vehicles. Enter a smart, convenient solution: the RideSafer Travel Vest, a wearable booster seat alternative for children from 3-5 years old, 30-60 pounds, and 35 to 48 inches in height.

The RiderSafer Travel Vest is a restraint system that your four-year-old wears in the car. The back of the vest attaches to the seat, and the seat belt holders attach to the car’s seat belt so that it is correctly placed across your child’s body. Safety and crash tested, The RideSafer Travel Vest meets Federal standards (FMVSS 213) and is legal in the United States.

While considered a booster seat, the RideSafer Travel Vest is safer and more comfortable than typical booster seats. You can fit this fest on your four-year-old before you need to use it, and that way it will be ready to go. All you do is open the buckle and the Velcro panel on the front, have your child slip her arms in, pull the vest down, fasten the Velcro, and adjust the strap if needed. The convenience and portability of this vest make traveling with children much easier. You can also fit three across in most car seats, so if you have more than one child, no worries!

Specs : 

  • Item weight—11.02 pounds
  • Dimensions—27.7 x 20 x 19 inches

In addition to four shoulder harness and two crotch strap positions, this seat’s design adjusts to fit a child as he or she grows.

One concern about this booster car seat is that its height limit isn’t high enough in the booster setting. The height limit is 57 inches, and some reviewers said that this doesn’t accommodate kids who are tall for their age. Also, this seat does not convert into a backless booster car seat, so that also was a common concern.

The Insurance Institute for Highway Safety (IIHS) rated this seat a “good bet,” which also makes us feel good about it.

Safety is high on our list, obviously, and this seat achieved impressive crash test scores and was also approved for use in Canada by the Transport Canada and Health Canada organizations. The three-position recline and padded body pillow allow for a child’s comfort as he or is she is riding in the car.

How Can You Determine The Best Car Seat For 4 Year Old?

Measure in Weight and Height, not in Years

Don’t rush out to buy a new car seat on your child’s fourth birthday. A child’s age is only a small part of the car seat decision process. You should choose a seat based on the child’s weight and height since all four-year-olds vary in size. If your child hasn’t reached his current seat’s weight and height requirement, it’s best to keep them there for a while.

On the other hand, if your three-year-old has outgrown his or her seat, it’s time to look for a new one.

All car seat manufacturers will tell you the recommended age and weight and height limits for their seats, but it’s up to you to decide which seat is best for your child.

Choose a Car Seat that will Accommodate Growth Spurts

Children grow rapidly, so if you don’t want to need to be buying another car seat in the near future, choose one that will accommodate a growing child. You will want to look at weight and height limits, as well as the maximum shoulder height.

Convertible car seats and all-in-one car seats are best for adapting to a child’s growth, and we will look at these types in detail.

Test the Fit

You want your child to enjoy riding in his or her car seat. Of course, we know this doesn’t always happen, but if your child does not like the seat, it could be because it’s just not a great fit.

You can go out and test some floor models before you buy, and it is worth your time and money to do so. See where the lap belt falls on your child in different models. In an accident, a belt that falls on a child’s abdomen rather than the thigh is not going to be absorbed properly to protect the child from injury.

In addition, the straps should fit snugly on your child. Overall, make sure your child is comfortable in the seat you choose.

Measure Your Backseat

Some car seats are larger and bulkier than others. If you have a smaller, compact car, make sure the seat will fit by measuring the space you have to work with and matching them with the dimensions of the seat. Make sure you consider and check that you have plenty of room for other passengers as well.

Think Twice Before You Choose a Used Car Seat

It is an intriguing and affordable option to move on to a used car seat, either the one older siblings used or a hand-over from extend family or friends. However, keep in mind that car seats have expiration dates. Always double check when a used car seat is set to expire and avoid ones that are soon to expire or overdue. If you plan to purchase a car seat from someone you don’t know, it is best to do your diligence to ensure that the seat was not involved in a car accident.

Types of Car Seats for a Four-Year-Old

Convertible Car Seats

Convertible car seats are convenient because they adapt to a growing child. Most of them include rear-facing, forward-facing, and then a booster seat. They typically accommodate infants from around 5 pounds to older children up to 100+ pounds.

Combination/All-in-one Car Seats

Combination or all-in-one car seats are forward-facing only (not to be confused with a convertible car seat, which is both rear-facing and forward-facing. A combination car seat has a five-point harness and will convert to a booster seat when a child outgrows the harness.

Booster Seats

Graco Affix High Back Booster Seat

Booster seats are necessary for children who weigh between 40 and 100 pounds. There are two different types – high back booster seat and backless booster seat, so understand the difference carefully before you choose between them.

High back booster seats include head and neck support and may also have adjustable headrest built in. High back boosters are useful for vehicles with low seat backs since these boosters provide the necessary head and neck support.

Clek Ozzi Backless Booster
Clek Ozzi Backless Booster Seat

Backless booster seats are just that—backless. It is light weight and portable. Backless booster seats are good to use if your vehicle already has head support and higher back seats and if car’s seat belt fits well with child’s body. Backless booster seat is a great option for school aged kids as well.

It is important to note that booster car seat should be used with lab and shoulder belts ensure safety.

If you are still not sure what type of car seat is best for your child’s needs, the American Academy of Pediatrics has a conclusive listing of available car seats. The list is organized by restraint type and includes height and weight requirements.

How to Install a Car Seat Correctly

We talked a bit about installation with each car seat we recommended, but we wanted to expand on that a bit. Correctly installing a car seat is essential for maximizing your child’s protection while riding in a car.

Each car seat is different, so it is imperative to check with the car seat’s installations instructions before you install it. These instructions come directly from the manufacturer and will give step by step detailed instructions on how to install properly.

Checking your car manual is also a good idea. Each car is different, which means they have a variety of safety features that will aid you in securely installing your car seat. Your vehicle may have anchors designed to help install the seat (or it may not). Consult your vehicle’s manual to look for these features before installing the seat.

After consulting both the car seat and your vehicle’s manual, you should have a good idea of how to install the seat. Keep these tips in mind, too:

Place the car seat or booster seat in the correct place.

Obviously, the car seat needs to go in the backseat as that is the law. The center of the backseat is the safest place to place a car seat since it’s not on the sides too close to the windows.

Make sure you lock the seat belts.

If your vehicle does not have anchors available for the booster seat, you should tighten and lock the seat belt around the seat once you install it.

Tighten the straps and adjust the angles.

Make sure that you tighten every strap so the car seat will not budge. Not tightening the straps tight enough a common mistake when installing a car seat.

The Bottom Line

Advancements in technology and car seat design has improved tremendously over the years. Most car seats pass FAA safety regulations (and if you come across one that doesn’t, run away!), and most car seats have even extra safety features.

Comfort is another significant factor to consider. Some car seats are more comfortable than others, so it’s best to look for seats with extra padding on the base, body, shoulder, and head areas.

Of course, then there’s installation. The LATCH system makes installation simpler, but not every car seat includes this system. You want a car seat that is easy to install. Don’t just look at what the manufacturer says though—go with the customer reviews. They don’t lie.

Then there’s the extra perks—color options, cup holders, etc. We do mention these features, but some customers value these factors more than others, so it’s up to you to decide what you are looking for in a car seat and do your homework!
