Buying the BEST CONVERTIBLE CAR SEATS for your child is perhaps one of the most important decisions you can make as a new parent. How tight is enough? forward or backward? To find the best car seats, we spoke to car seat safety experts, including Lorrie Walker, safety and education advisor at Safe Kids Worldwide.

In the early stages of your baby’s life, you will notice how quickly he develops in certain elements.

Unlike infant car seats, convertible infant car seats are usually an integral part of a family car. (If smooth transportation of a newborn is a priority, consider a car seat.)

The parenting and product experts at Suggestmeshop Little Lab test everything for babies, toddlers, and kids, from strollers and safety rails to toys and everything in between. Last year, we tested over two dozen convertible car seats to find the best ones, and to rate company safety, customer service, ease of installation, angle adjustment, and seat belts. We run our tests on vehicles of different sizes in every configuration described in the owner’s manual. These are the best convertible car seats to buy:

How to Choose the Best Convertible Car Seat?

All child seats in the United States must meet uniform state safety standards.

Here are some factors to consider when choosing the best convertible car seat for your child and family:

Fabric: In addition to finding a fabric to your taste, consider its durability and how easy it is to wash if it gets dirty.

Safety Indicators: Some car seats have built-in adjustment systems and indicators to show that they have been installed correctly.

Height And Weight Restrictions: Each convertible child seat has height and weight restrictions for rear and front facing and, where applicable, supportive configurations.

Installation Efforts:

Correct installation of a child car seat is critical to safety, but a great deal of force may be required to properly secure the seat. Many seats are compatible with LATCH (Children’s Low Harness and Harness), an easy-to-use system that includes straps, cuffs, and hooks on both the car seat and car for a secure connection. If your vehicle is not LATCH compatible, you will likely have to install the car seat using your vehicle’s seat belt. If you need help adjusting your car seat according to the instructions, get a professional.

Viechle Size: Measure the available space in the back seat of your car before deciding which car seat you want to purchase.

Easy To Clean: Keep it simple, and look for models with removable seat cushions and machine-washable covers.

Seat Adjustment: Since a convertible car seat can accommodate your child from newborn to toddler, find a seat that can grow with them with headrests and multiple reclining positions. Wireless seat belts allow easy seat adjustment without the need to reformat the seat belt.

Expiration Date: If you plan to use the same chair for years or for several children, consider the recommended use. Never use an expired or accident car seat. This is especially true when purchasing a wheelchair car seat.

What is a Convertible Car Seats?

The convertible seat begins in a rear-facing position for infants and toddlers, then rotates forward as your child grows. (Some convertibles even convert to booster seats for school-aged children.) This convertible car seat can take you from day one to kindergarten.

When Do You Need a Convertible Car Seats?

At some point you need a convertible car seat; It is only a matter of time.

Some parents use convertible car seats from day one. Others choose to use a car seat first and then switch to a convertible child seat when their young child reaches the maximum seat height or weight, usually on their first birthday.

This is because convertible car seats are not as portable and lightweight as car seats. Unlike car seats that mount directly to the base and are designed to fit inside and outside the vehicle for easy transportation, convertible seats are mounted directly to the vehicle using a LATCH system or vehicle seat belt. The latch stands for lower anchors and lower child harnesses and is a system designed to facilitate proper attachment of child car seats without the need for a seat belt. Please note that the use of the latch to secure the car seat is subject to certain weight limits. You can read more about it here.)

Do Convertible Car Seats Have Strollers?

Currently, there is only one convertible car seat on the market that is compatible with a stroller. There are some lightweight convertible seats that are good for travel, but the inconvenient truth is that as your little one grows out of his booster seat, he will lose the ability to easily move the car seat straight into the stroller.

When to Switch from Infant Car Seats to Convertible

According to Rebecca Kimenau, a child registry consultant and child safety specialist (CPST), your child can stay in a car seat until they are older on the seat with height or weight restrictions.

It is important to remember the “or” here. This means that even if your child meets the seat weight requirements, but exceeds the height requirements, it’s time to replace it and vice versa.

Consult your child’s seat manual for the exact height limits for your particular seat, but a good general rule of thumb is that if the top of your child’s head is an inch away from the top of the car seat, it’s time to replace it. (The easiest way to test this is to find a picture book about an inch thick and place it over the child’s head while they are sitting firmly in the seat.)

1. Graco Extend2Fit Convertible Car Seat

Graco Extend2Fit rental in Truckee, CA


  • Great choice for smaller vehicles (but not for three-across).
  • Built for extended rear-facing.
  • Affordable choice, easy to install.


  • None

In our crash test, Graco Extend2Fit ranked second after Britax. It’s not as easy to install as the Britax ClickTight system, but our testers managed to get a fairly snug fit without much effort. The 22-pound Graco Bench is lighter than the 28.4-pound Britax Bench, which means the Graco is a bit easier to move around. It also has a much higher rear-facing weight limit than the Britax Marathon ClickTight (50 pounds versus 40), which means you can keep an older child rear-facing in this seat for longer if you like. † And unlike Britax, the Graco stool has not one cup holder, but two integrated cup holders.

What Our Experts Say

Extend2Fit is an affordable convertible child seat and a consistent favorite for three main reasons: high rear-facing weight limit, ease of installation, and good compatibility with nearly all types of vehicles.

One of the biggest advantages of this seat is its 50-pound weight limit, which allows kids to stay rear-facing for longer than many other convertible seats. There’s also a retractable footrest (as the chair’s name implies) that provides an additional five inches of legroom to make the extended rear swivel more comfortable. Since the seat can sit almost vertically when facing backwards, this means that taller parents or those with smaller cars can sit well. It also works well for children of all ages, from newborns to school-aged children.

What’s Worth Considering

The seat cup holder must be attached, which makes the seat wider and is not the best option if you are looking for more space in the back seat or if you want to put three seats side by side. This seat is also not a good choice if you plan to turn your child forward before they weigh 40 pounds, due to a strange rule that requires the seat to be at a certain angle, resulting in a configuration that is nearly impossible to sit on right.

Both the AAP and the NHSTA advocate that children stay in their car seats in the back for as long as possible, and broader height and weight restrictions make safe seating longer. Graco’s Extend2Fit Convertible Car Seat has one of the highest height and weight limits, with a maximum height of 49 inches and 50 pounds, which is over the 90th percentile for a 5-year-old. Plus, the adjustable extension bar gives your growing child up to two inches of extra space, eliminating the fear of foot cramps. The 10-position headrest and 6-position backrest ensure a comfortable sitting position, regardless of your child’s height. And at just over $234.99, it’s one of the most affordable options out there.

What We Liked

As for safety tips to keep kids behind for longer, this convertible seat offers more legroom and an ergonomic footrest to keep feet from getting stuck. We love the fact that it also performs great in crash tests.

Kenny Fried, Vice President of Brotmans | winter | Fried tells me, “I transfer car seats from a car to a truck, and the sheer simplicity of the ClickTight system makes it special.
