Since kids are the safest in the rear facing position, this convertible seat has a four-position extension panel to provide five inches of additional leg space for your kid in a rear facing position.

Moreover, it reclines in six positions, while the headrest can be adjusted between ten different positions. What is more, the adjustment takes no more than seconds thanks to the Simply Safe Adjust Harness System, specially designed to enable harness and headrest adjustment in one motion.

Graco Extend2Fit 3 In 1 Car Seat passed rigorous crash testing and temperature resistance to ensure your child is always perfectly safe in this convertible seat, no matter the circumstances.

This 4Ever DLX 4 in 1 car seat features a four-in-one design transforming from a rear facing harness infant seat (for kids from five to forty pounds) to forward facing harness seat (for kids from 22 to 65 pounds), high back belt booster seat (from 40 pounds to 100 pounds) and a backless booster (from 40 pounds to 120 pounds).

Cosco Apt 50 Convertible Car - Budget-Friendly Best Car Seat Convertible

Next off, we selected one budget-friendly option that could prove quite convenient for savers. The seat in question comes from Cosco, and it can be used for the first two stages in a child's growth: rear facing and forward facing.

This Cosco convertible car seat can be used to accommodate infants from 5 to 40 pounds in rear facing position, and toddlers up to fifty pounds in forward facing position. Whatever mode you will be using the car seat in, the built-in side impact protection provides additional safety to your child.

Finally, I would personally recommend this seat for families that already have a booster seat or need a more cost-efficient seat to get through the first two stages in a child's growth.

However, I believe that 3-in-1 seats are better investments in the long run as you won't need to buy additional harnesses or seats once your child overgrows the forward facing position.

  • Two positions
  • Federally approved
  • Can be used on aircraft

Britax Marathon ClickTight Convertible - Excellent Two-Stage Convertible Car Seat

Britax is another leading car seat manufacturer, yet it sort of lost the customers' trust after its massive recall of the rear facing infant car seat in 2017.

However, recalls are pretty standard, and if one car seat is recalled, it does not mean that other models are faulty. This convertible car seat, for example, meets all the federal standards perfectly and can be used on aircraft.

Namely, the Britax Marathon is the combination of the rear facing infant car seat, built to accommodate children from 5 to 40 pounds, and a forward facing toddler seat for children 20- 65 pounds in weight.

I believe that every parent has heard of Chicco; their baby equipment is sold worldwide and keeps its supremacy on the market list.

Why? Well, the quality of their products is at the highest level, while innovative technology makes them honestly functional and safe.

The car seat we will talk about is the best convertible car seat from Chicco, Chicco NextFit Zip Convertible. It features two different modes, a rear facing infant car seat for kids from 4 to 40 pounds in weight and a forward facing toddler seat with a weight limit from 22 to 65 pounds.

Maxi-Cosi Pria 85 Convertible Car - Extended Use in Forward Facing Mode

At last, the final item on our list of convertible car seats is this low key yet remarkable Maxi-Cosi convertible car seat with two modes. Namely, this model can support children in rear facing and forward facing mode, with extended use.

Your children can drive in a rear facing direction if they weigh from fourteen to forty pounds, while the use in forward facing direction is allowed for kids from twenty-two to eighty-five pounds.

This is quite extraordinary because usually forward facing car seats can support children up to 65 pounds.

What I like about his convertible car seat is the five-point harness system with harness holders that keep the straps off your way and make it easier to place your child in the system. The harness adjusts from the front of the seat with one-hand harness height and adjustable headrest.

What is more, this seat includes the innovative FLETCH system that manages energy multi-directionally while the Air Protect includes safe side impact protection. This guarantees that your child will drive safely every time.

Importantly the seat meets ASTM and JPMA standards and can be used on aircraft. It is also easy to clean with the removable and washable pads.

What I don't like about this seat is the bottom limit for the use, which is eleven pounds, way higher than other infant rear facing car seats with the bottom limit four pounds.

This means that you won't be able to accommodate your newborn right out of the hospital in this seat, which is by no means practical. Also, the seat does not have a booster car seat mode, so once your child exceeds 85 pounds, you'll have to figure it out.

Still, it does have a higher limit for the front facing stage, instead of 65 pounds, it allows twenty pounds heavier children to be accommodated.

1. Make Sure Your Car Seat Follows All the Stages of Growth Your Baby Goes Through

The best car seats follow all the stages in your child’s growth. What does this mean? 

Well, if you're buying a convertible car seat, make sure it can be used in a rear facing, forward facing, and booster seat mode. In this way, one car seat will be all you'll need for your baby.

2. Check the Weight Limits

The best convertible car seat has an honestly wide weight limit.

This is important because you want to accommodate your baby as soon as it gets out of the hospital to the point when he/she can use a safety belt.

Therefore, your convertible car seat should support your child in a rear facing mode from at least 4 pounds to somewhere around 50 pounds, and in booster mode until 120 pounds.

3. Make Sure Your Car Seat is Federally Approved and Faa-approved

Your car seat will be useless if it does not meet the federal standards. It is also a handy addition if you can use it on aircraft, as the recommendations say it is best to keep a baby in a rear-facing car seat during the flight.

Therefore, the best convertible car seat is FAA-approved and meets the ASTM and JPMA standards. 

4. Check the Safety Measures

The reason why you should use the best car seats is the fact that they protect your child in crashes.

So, when you're choosing the best car seats, check if they passed the crash tests if they have impact protection and energy-absorbing foam.

5. Additional Features

Innovative technology always comes handy, mainly when it includes easy installment, harness holders, LATCH system, no-rethreading harness, adjustable backrest and headrest, and many new additions that will make your life easier.

So always opt for advanced options.

6. The Price

I know that many families are on a tight budget, yet you really should not save on baby equipment.

Options below $100 are questionably reliable and usually include only two modes, rear facing and forward facing. Hence, you can always apply for the BuckleUp program, where they can provide you with a reliable car seat.
