What Are the Best Car Seats for a Three-year Old?

There are quite a few car seats that we will discuss, but we have labeled them into categories, which are convertible, all-in-one, and toddler booster seats for your convenience.

Convertible Car Seats

Once the infant seat is over with, the convertible chair is your next option. Although you can quickly get an all-in-one, you can still use these seats for quite some time before transferring to a highback booster seat. So, without further ado, here are the best convertible car seats, according to Consumer Reports.

1. Chicco NextFit Zip

The first convertible car seat is the Chicco NextFit Zip. This car seat is a good choice because of its features. 

The Chicco NextFit Zip scored an incredible 85 on Consumer Reports. Consumer Reports noted that this car seat had one of the best crash protection safety results, its ease of use, and the rear and forward-facing latch system fit well in the car.

This car seat has two layers of protection: a deep rigid shell and EPS energy-absorbing foam, leaving it to be a great car seat. 

On top of that, the rear-facing mode can hold between 5 to 40 pounds, leaving plenty of room to rear face without worrying about putting your child forward-facing at an early age. In the forward-facing position, you can do so as early as 22 to 65 pounds. 

The Chicco NextFit Zip contains a 9-position recline system to fit whatever your child needs or wants. This car seat includes an easy installation with a level and tightening system, making less effort for you. 

In cleaning the Chicco car seat, you can put the fabric in the washing machine by simply zipping the top off, allowing the car seat to remain in the car, making it less hassle. This is a good thing because the Chicco car seat is known to be a heavy seat.

The backflow for the car seat contains breathable fabric, making it where your kids will be comfortable in the car ride instead of remaining hot constantly. 

Lastly, you can extend the Chicco NextFit Zip to 25% more leg room than a regular car seat, leaving the rear-facing seat much more comfortable while providing calf support in a forward-facing way.

2. Britax Boulevard ClickTight

For our first Britax review of the day, we have the Britax Boulevard ClickTight. This particular brand is one of the best brands you can get because of its locking mechanism, the ClickTight system. It ensures a tighter grip and keeps it to where the car seat does not bulge out of place. 

The first thing we will discuss is the Consumer Reports log. They mention the Britax Boulevard ClickTight scores a very high 84 on their website, ensuring it to be a great choice. 

Their test results show that their crash protections remain at best. Their rear latch, forward latch, rear belt, and forward belt scored a 5/5, while the ease of use scored a 4/5. 

The Boulevard is unique because it contains 30% bamboo charcoal, meaning that this car seat keeps your three-year-olds cool during those hot summer days. The chair keeps away any moisture created to keep your child dry. 

This car seat comes with 2-layer side protection, creating an external cushion that surrounds your little one’s neck, head, and torso. It contains an energy-absorbing shell with a foam-lined headrest. 

Your child will easily be able to grow in this seat as it contains 14 adjust harnesses and headrest positions.

The Advocate also achieved a 4/5 on the ease of use, which you might expect because the Boulevard was the same way. 

However, that does not show off its excellent qualities and features, as the Advocate contains three layers of extra impact protection, a steel frame, and an impact absorbing base, ensuring the safety of your little one. Not to mention its V-shaped tether, creating a slow and reduced forward moment if a car accident occurs. 

On top of that, the Britax contains the ClickTight system, guaranteeing the installation process is relatively easy to secure and put in. 

You do not need to worry about rethreading the harness, as you can quickly adjust the seat in a 14-position harness, ensuring the perfect fit for your baby to grow in. 

For the weight limit, you will be happy to hear that the Advocate backward faces from a minimum weight of 5 to 40 pounds and front faces go from 20 to a maximum weight of 65 pounds, making it where your child can continue to grow for quite some time.

However, you do not need to worry, as this seat is machine washable, ensuring you do not have to scrub everywhere.

5. Graco TrioGrow SnugLock LX 3-in-1

For our top pick of all-in-one car seats, we have the Graco TrioGrow SnugLock LX 3-in-1

  • Forward-facing harness from 22 to 65 pounds.

You can also recline the car seat in six ways, making traveling for long road trips a breeze. 

As with the other convertible car seats, you do not need to reread the harness constantly when your child grows. All you do is adjust the headrest according to when your three-year-olds grow, making it much easier to use. 

On Consumer Reports, the Graco Trio Grow scored an overall 83, with the crash protection being at best. 

This particular car seat also came with a 5/5 with the rear latch, forward latch, booster fit, rear belt, and forward belt.

What Should I Look For in a Car Seat?

There are quite a few things you should look for when it comes to a car seat. These significant considerations include the following:

  • Safety
  • Ease of comfort
  • Size
  • Installation
  • Portability
  • Maintenance
  • Certain features
  • Price range

1. Safety

Considering how we look up car seats, the most important thing to consider is ensuring it is child safe. In doing so, you want to look at any crash protection a car seat provides. 

The National Highway Traffic Safety Administration (NHTSA) and the Federal Safety Standards are the ones that set rules and regulations for road safety.

All car seats mentioned above pass the crash protection test, and every new car seat sold in the USA must meet the minimum road safety standards.

You can also go to the American Academy of Pediatrics (AAP) for more information on car seat safety. 

The AAP recommends infants and toddlers should rear-face as long as possible. In that case, although many car seats mention children can forward face as early as 22 pounds, it is safer to keep them rear-facing. 

2. Ease of Comfort

Suppose you previously bought a car seat that gets hot relatively quickly, or the car seat was charcoal black that loves the sun. 

In that case, you will want a car seat that leaves your little one feeling comfortable and well-rested. If your child constantly complains or cries about getting in the chair, you might consider finding something comfortable and easy to use. 

3. Size (Height & Weight)

Depending on the size of your child’s head and body, you will want to consider how long they will fit in the car seat. 

For example, if your husband or wife is roughly 6 feet tall, your three-year-old might go through a growth spurt when they have that seat. If that is the case, you want to consider all your options during that time.

Another thing to consider is your infant. If the car seat does not come with an infant insert and your little one is 7 pounds, they would not fit properly. In that case, ensure the weight limit is up to par for your baby’s needs.

When your child is properly secured in their seat, the CDC estimates the risk of dying in a car accident goes down by roughly 71%. 

4. Installation

Installing a car seat can be a pain, so ensure you find features with easy installation processes, like the Britax ClickTight method or finding something where you do not need to pull as much. 

Another question you might want to ask yourself is if the car seat can fit in small cars. It might not work if you purchase a bulky seat like the Nuna Rava. However, if you have something small with a more compact design, it would fit much better. 

5. Portability

Car seats can be relatively heavy, but there are still some out there that are more lightweight than others. In that case, this might be a consideration you want to account for.

Do your children go with their grandparents often, or are you planning to take them out when you clean your car? What about when you tend the car seat, or you go on a vacation by plane? 

If you have a 25 to 30-pound seat, it is not easy to lift constantly. The good news is there are quite a few car seats that do not require much heavy lifting. 

6. Maintenance

Washing the car seat can often be overlooked because many parents do most of their research on the safety aspect of it. 

In that case, how easy is your car seat to wash and maintain? Do you need to take the entire base out, or can you zip or snap off the fabric to throw it in the washing machine?

It might not be a big deal if you have one child, but this can be a daunting task for those with multiple children. 

7. Price Range

Some families are on a budget, so make sure you find a specific price range before finding what is best for you. 

Many parents are willing to spend between $100 for a basic model and $300+ for a premium model. 

Some models and brands are more expensive due to their materials, features, and finishing. 

However, that does not necessarily mean a more expensive item is better than the other, as all car seats sold in the USA pass the minimum safety standards.

8. Certain Features

Although you do not need specific features for a car seat, it might be nice as a bonus. Let us consider some of the options you may or may not want. 

  • Anti-rebound bar: This prevents the car seat from bouncing up and down if a car accident occurs, so it is for better safety.
  • Five-point harness: A five-point harness is on many modern car seats today. You’ll notice two shoulder straps (one per side), two waste straps (one per side), and one strap between your child’s legs.
  • Car seat base: Many infant car seats come with a car seat base to which you can connect and disconnect the chair. It is not necessary for toddlers but might be a feature you want to consider for your youngest child if they’re small enough. 
  • Breathable fabric: During the summertime, car seats can get extremely hot! So, ensure you have material that your little one can breathe comfortably. 
  • Expiration date: All modern car seats should come with an expiration date. They expire for many reasons, such as wear and tear, recalls, regulation changes, etc.
  • Cushion side impact: Having multiple layers of side impact protection helps with safety and comfort for your child’s head.
  • Non-rethread straps: Not too long ago, you used to have to rethread the straps constantly when your child grew older. Nowadays, we do not have much of that issue as you pull the headrest up according to your little one’s height, so it is less of a hassle. 

Conclusion

There are many car seats available for your three-year-old. All the ones we mentioned above ensure your child’s safety and comfort and can fit into most budgets without any issues. 

The most important thing to remember is that you are making an informed decision that will last your little one a relatively long time. We wish you the best of luck in finding the right one for you!
