How To Buy The Best Car Seat for Six Year Old?

While buying the best car seat for six year old, you need to check a number of features of the car seat. Only buy the car seat if it ticks all of the features mentioned below:


So, what makes a car seat the best car seat for 6 year old? You have to mull over certain essential features to decide what car seat for a 6 year old is better than other offerings. First and foremost, the seat has to be lightweight. If you want an exact weight count, we would say don’t cross the 10lbs threshold.

Ease of Use & Durability

Also, it has to be easy to use. You don’t want a complex setup procedure involved whenever you want to go out on a ride with your family. User-friendly car seats for 6 year old child would save you a lot of time and trouble. And, it also has to be durable enough to last a few years. Your kid will outgrow the seat in a matter of years, and a single seat should make do.

That said, if the seat is quite inexpensive, but you feel that it is a comfortable booster seat for 6 yr old, then it makes sense to buy it regardless of the durability. If it becomes unusable in a year or so, you can replace it without breaking the bank. If you add up the costs, then you will see, it costs the same or even less than more expensive car seat options.

The Body Shape of Your Children

As we pointed out earlier, needs would vary across families because of the differences in the physical profiles of their children. If your kid has a taller shape, then a few more years of harnessing could benefit him/her. Keeping that in mind, you will have to go for taller seats, even though they will cost you a bit extra.


Padding would also be a crucial factor to look at if you go on long drives often, or plan to use the seat in airplanes. On that note, we don’t think you would need a special seat in airplanes for your child. The airplane seat designs are more suitable for 6 year olds than automobile seats. So, only pack a baby seat if you plan on driving a lot in the place you are traveling to.

Refrain from Buying Used Car Seats

Did you find an old booster seat for 6 year old on eBay that is priced at half the price of a new one? While that sounds like a deal too good to refuse, pediatricians would advise you to steer clear of used car seats. The car seat fabric might contain unknown germs and bacteria that can cause skin distress to your children.

At this point, you might be thinking “Big deal! I’ll just wash it thoroughly before use.” Yes, that would eliminate some of the threat associated with it. We say “some”, because there is still a good deal of risk involved. The seat cover fabric comes with specific expiration dates. After the expiration deadline passes, it could release harmful toxins.

Unfortunately, no matter how thoroughly you clean the seat fabric, you can’t make an expired seat covering safe for use. When you buy a seat second-hand, there is no way to know when the exact expiration date is. So, purchasing old car seats for six year olds is not worth the risk, no matter how cost-effective it is.

Best Car Seat for 6 Year Old: Classification

As you have seen in our top 10 recommendations for the best car seat for six year olds, there are many kinds of car seats in the market. Some of them have harness or booster-only designs, while others incorporate a multifaceted mechanism. These all-purpose seats can transform from one form to another in a matter of seconds.

In the following paragraphs, we will break down these classifications in more detail. We will try to draw a clear line between forward-facing seats, aka harness seats, and booster seats. These are the only seat categories the National Highway Traffic Safety Administration greenlights for children aged six.

Forward Facing Car Seat

Forward-facing car seats harness the mobility of your kids. These types of seats are more appropriate for younger kids, who are yet to develop the maturity to sit calmly in the car seat. However, there is no guarantee that children will gain the wisdom of a responsible passenger at a certain age.

So, there is no guarantee how long you would need to use the harness for. For some kids, that stage will come well before six and some might need longer to show such mellowness. If your kids sit idle and respond to your directions immediately, you wouldn’t need to use these seats. Otherwise, forward-facing car seats are a necessity for you.

Booster Seats

Booster seats can be seen as a sign of parental confidence. When you trust your kid to sit in a booster seat, you are convinced that he has become intelligent enough to move responsibly inside the vehicle. NHTSA guidelines state the transition age to be between four to seven years. But, this is not a definitive age group for booster seat compatibility.

Booster seats usually accommodate larger body shapes than forward-facing ones. So, it would be ideal to shift from harness to a booster seat when your child reaches a certain stage of growth. However, you must make sure that you can rely on him/her to not exploit this newfound freedom and start making reckless movements.

Therefore, you should pick the type of seat that suits the physical and mental stage of your children.

Frequently Asked Questions

What car seat should a 6 year old be in?

A six year old needs to be in a car seat that makes up for their smaller physique and allows the seatbelt of the car to secure their position. We can use either a forward-facing car seat or a booster car seat.

Forward facing seats are appropriate for younger children, who are agile and more vulnerable. Booster seats, on the contrary, are aimed towards children who have developed a greater sense of responsibility. We would recommend purchasing a car seat that can be used both ways.

What is the safest booster seat for a six year old?

We have reviewed some excellent booster seat for six year old. However, if we were to isolate one for its safety features, it would be Evenflo SafeMax 3-in-1 combination booster seat. With E3 Side Impact protection, it offers premium security to protect your kid in the worst possible scenarios.

How safe are backless booster seats?

Backless booster seats offer a decent amount of protection, but they are not as good as high back boosters. The most common safety flaw in backless booster seats is that it often fails to keep the shoulder belt of the vehicle stay in place. Some backless booster seats address this issue by introducing a special shoulder belt clip. You can buy one with similar clips for better safety.

What is the difference between a 3-point harness and a 5-point harness?

A 5 point harness consists of two straps for waist, two straps for should along with one that goes between the middle of the legs. With 3 point harnesses, you don’t get waist straps, so the hip region remains unprotected. Always opt for a 5 point harness over a 3 point one.
