1. Chicco NextFit Sport Convertible Car Seat

Our rating: 9 / 10

Chicco NextFit Sport Convertible Car Seat

Check Price on Amazon

Pros:

  • Excellent LATCH system
  • Highly adjustable
  • Higher weight capacity
  • Forward and rear-facing

The NextFit is one of the most popular convertible car seats on the market because of its ease of use and stay put technology. The NextFit is really easy to install thanks to its LATCH connectors, which keep the seat stable. The downside is that not every vehicle comes equipped with LATCH connectors, so you may have to install it the old-fashioned way, with the seatbelt. The process is not difficult, just extremely frustrating if you’re in a hurry!

When you use the LATCH system, you can easily switch from rear-facing to forward-facing, thanks to the seat’s highly adjustable 15-position headrest and 12-position harness system. The seat’s Handi-harness adjustment system allows you to adjust the harness without having to rethread it, and its deep Energy- absorbing shell further protects your infant in a crash.

Additionally, the NextFit has a three-position recline, which means your baby can nap comfortably in the car. Its higher weight limit (up to 65 pounds!) combined with a three-position recline means the NextFit can accommodate some kids from birth up until they are ready to ride in a booster seat.

The Graco Extend 2 is a convertible car seat with a range of installation options for rear-facing, forward-facing, and high-back booster mode.

The Graco SlimFit is another car seat that is easy to install, and it’s designed for children from four to fifty pounds. It’s U-shaped, slim design allows it to fit into narrow spaces and is basic black.

Some of the reason why I like this infant seat better is that I like that it’s easier to adjust, fold, and lock with one hand. It’s also a lot more comfortable for the baby.

This car seat is recommended for children from 5-50 pounds rear facing and 22-65 pounds front facing. When used rear facing, it best fits children 5-40 pounds and newborns under the height of 29-inches.

As it weighs around 25 pounds, you might need a friend to help you carry it. It is recommended for children below 2-year old plus 30 pounds. It also comes with a 5-point harness that is adjustable and an EPS energy absorbing foam.

Graco Extend2Fit Convertible Car Seat

Check Price on Amazon

Pros:

  • Can use seat from 5 lb to 120 lb
  • Can be used forward facing or rear facing

Graco’s Extend2Fit Convertible Car Seat is going to offer more versatility than most other ones on the market because it’ll give you the option to use the seat rear facing comfortably up to 40 pounds or forward facing from 20 pounds and up. It can be hard to find car seats that don’t limit you to rear facing only until a certain weight (usually 25 pounds).

Getting the Extend2Fit installed can be difficult. It’s definitely not one of the easiest car seats to install in the market, so take that into consideration.

10. Safety 1st Grow and Go 3-in-1 Car Seat

Pros:

  • Feels safe and comfortable

11. Cosco Apt 50 Convertible Car Seat

Our rating: 9 / 10

Cosco Apt 50 Convertible Car Seat

Check Price on Amazon

Pros:

  • Affordable
  • Easy to install
  • Padding is thick and comfortable

There’s no doubt that the Car Seat has been improved thanks to some new features like the steel frame, padded headrest and pivoting armrest. Also, the Cosco Apt 50 car seat is a good value for the money that you’ll pay.

Here are some of the things that we think are really cool about the Cosco Apt. First, the LATCH system makes it easy to attach the carseat to the car. The front is easy to recline as well as to adjust the height of the head rest.

The seat is highly comfortable and supportive when compared to some other seats. The best seat belts for securing this 5 point baby seat have been long as the LATCH system is offered in this seat.

12. Graco Contender 65 Convertible Car Seat

Our rating: 8 / 10

Graco Contender 65 Convertible Car Seat

Check Price on Amazon

Pros:

  • Reasonable price point
  • 3-position recline feature
  • 5 point harness
  • Versatile seating modes
  • Durable and washable fabric
  • Secures to car effortlessly

Cons:

  • Too large for small compact cars
  • No cup holders
  • May be too heavy for smaller passengers
  • Not the most aesthetically pleasing car seat

The Graco Contender is a good baby car seat that is both budget friendly and functional. The seat itself is great for larger babies as it can convert to different seating modes.

The car seat itself is heavy and bulky, which is more of a downside when you consider that more safety features often lead to heavier and bulkier car seats. Also, if you have a smaller vehicle, then you might want to consider getting a lighter car seat as this one may not fit in your car.

As far as aesthetics go, the car seat is not the prettiest of seats, which could be a turnoff for some parents. Some people may need to adjust the car seat more than others to properly secure it with the latch system.

Overall, I highly recommend this seat because it has everything you need for the price. It isn’t the most hassle free seat, but you will get there.

Most importantly, this seat is incredibly comfortable with thoughtful design decisions given to the fabric, padding and harness. Your kids will be happy.

The other nice thing about this seat is the overall size. It is smaller than some models, which is great if you are looking for the smallest car seat possible in your vehicle.

Pros:

24. Britax Advocate ClickTight Convertible Car Seat

Our rating: 7 / 10

Britax Advocate ClickTight Convertible Car Seat

Check Price on Amazon

Car seats from Britax are among the best in the market today. They are a trusted brand by parents and are in high demand when there is a sale.

This car seat can be used from 5 of age and it can be used for about 2 more years. Moreover, it can be used for both rear and forward facing.

This is one thing that has stood out for me in this car seat. Most of the car seats can only be used from a particular side. That is the reason why most parents would have to use two car seats at the same time in order to have their kids facing forward in their vehicle. If you want to be able to move from rear to front easily, this is a great option.

What is the safest convertible car seat 2019?

  • The safest convertible car seats of 2019
  • 2 safety factors to consider when choosing a convertible car seat
  • Frequently Asked Questions

Q. Can the harness drop down? Must it stay up?

A. Firstly, the requirement that a car seat meet is in the USA is that the harness has to stay in place during a crash. In other words, you can’t have it drop to the child’s hips every time the seat is used. This means that if the car seat manufacturer anticipates a child will be around the 50 lbs mark, they must have an option to raise the harness to accommodate. There are some car seats, however, that allow you to adjust the harness higher for smaller infants. Sometimes this is done with a separate strap or in conjunction with a T-strap which can add up to 20 cm to the height.

What is the most comfortable convertible car seat?

First Dimension- It is important to check the dimensions of the seat to ensure they meet your needs. You want to make sure that you have sufficient head support for your little one and also that you can fit the car seat into the base and the vehicle.

Second Dimension- There are different weight and height restrictions on convertible seats. It is important to check these as well, especially if your child is close to reaching the limits on height or weight. The limits are based on the rear facing position.

Safety- It is important to choose a seat that was rated highly for safety. While this might sound like a no-brainer, you can be disappointed in the results. For example, a parent might purchase a seat and not come back to review ratings until the seat is too old to replace. Thus, the seat that she bought is no longer rated with the same opinions that it had back when she originally purchased it.

How do I choose a convertible car seat?

There are a lot of criteria and factors that go into purchasing the best convertible car seat. Ultimately you want the car seat to transition your baby safely from infancy to toddlerhood. Such a seat should:

  • Transition from rear-facing to forward-facing
  • Attach securely to the vehicle’s seat belt
  • Be suitable for the child’s age group and size
  • Be properly positioned and installed in the vehicle

Conclusion

There's no doubt that if you want to be safe in your car and you want your child to be as safe as possible in case of an accident, then at some point you'll need to invest in a car seat for your little one. But what's the best type of car seat for babies and toddlers, and how do you choose the right one for your family's needs?
