4 Best Safety First Car Seats [Safe Durable & Nontoxic]

Like most parents, car seat safety ranks high on your list of priorities. However, the dizzying array of travel systems on the market can confuse even the savviest shopper. Comparing car seat features seems to require both an engineering degree and infinite patience. Plus, you need to verify that the product is made from durable and non-toxic materials. 

Keep in mind that there’s a reason for all of those innovative safety features. According to the CDC, riding in a car is one of the most dangerous activities you can do with your children.

Unfortunately, seat belts do not provide enough protection for smaller passengers. Without a well-designed car seat, even a simple fender-bender can seriously injure an infant. Innovative safety features are usually costly, but it’s possible to find more affordable options.

Based on our research, the best convertible travel system is the Safety 1st Grow and Go-Best 3-in-1 Seat. Initially, you can use it for babies between 5 and 40 pounds. It then converts to a forward-facing position for children weighing 22 to 65 pounds. Eventually, it transforms into a booster seat that supports 40 to 100 pounds. This car seat consistently gets near-perfect safety ratings and positive reviews on car seat sites. 

Your child is kept safe from side impacts and rollovers, thanks to the patented QuickFit Harness. To ensure comfort, this car seat has an adjustable harness, modifiable headrest, and a 3-position recline. Special pillows in the rear-facing position also keep your infant nice and cozy. Not only that, but its compact design makes it ideal for smaller vehicles.  

After testing several products, we’ve found that the most durable is the Safety 1st Continuum 3-in-1 Convertible Car Seat. It’s suitable for children between 5 and 80 pounds. Like the Grow and Go-Best, it can transform from an infant seat to a booster for older kids. The Continuum 3-in-1 is made with high-quality and long-lasting materials so you don’t have to shell out money every few years on a new car seat.

Are Safety 1st Car Seats Non-Toxic?

We as parents worry about whether our children are safe in their car seats. It’s no exception when it comes to a car seat being non-toxic. Currently, NHTSA requires all car seat manufacturers to meet a mandatory flammability regulation before a car seat can be released into the market. Therefore, Safety 1st uses a minimal amount of fire retardant on all of their seats.

All their car seats are made of synthetic and natural cotton neoprene blend. Consequently, none of their Safety 1st car seats are completely non toxic.

However, they are still considered safe even for a newborn since they only use a minimal amount of flame retardant that is required by law in the US.For more info on which car seats are non-toxic, check out our Best Nontoxic Car Seats Reviewed.

Buyer’s Guide

This buyer’s guide will take a look at the durability, intended years of use, and most importantly, the safety ratings of car seats from the Safety First brand.

Each seat will be ranked based on these factors so that you get a clear idea of each seats’ advantages and disadvantages. This will ultimately allow you to choose the best option for you and your child.


A car seat’s durability is based on how much weight it can support, and its resistance to the impacts of a collision. Most of the car seats in the table below work in two different positions: rear-facing for infants, and forward-facing for older children.

Others also function as a booster side for children up to 100 lbs. Generally, in the rear-facing position, the seats below can support an infant weighing up to 40lbs. In the forward-facing position, the seat can protect a child weighing up to 65lbs.

Intended Years of Use

The intended years of use will let you know how long the seat lasts until it expires. Just like any other product, car seats have a shelf life. The special materials in the product that are used to keep your child safe, will eventually break down as it becomes used and worn.

To make sure that your child is receiving the maximum level of protection from their car seat, it is best to be aware of its expiration date. The date can often be found online on the manufacturer’s website, or on the product itself.

Safety Ratings

Other ratings from both and the manufacturer’s website are included to give you a clear overall idea of how well the product functions. In addition, ease of use rating from the National Highway Traffic Safety Administration (NHTSA) is also included. This will let you know how simple the installation process is for each product on the list.

Why Safety First Car Seats Are A Great Option?

While every car seat included on this list is a great option to keep your child safe, each one has its own unique features designed to provide safety and comfort. In the end, we chose the Safety First Grow and Go 3-in-1 Convertible Car Seat as the top option.

Its high-functioning safety features and good price make it a good choice for parents looking for protection that will last them in the long run. But as you explore the list above, you may find that another option better suits the needs of both you and your child.

Each Safety First car seat is an excellent choice when it comes to providing your child with the best safety and protection possible when you are out on the roads together.

  1. Hi, Tanya!
    Based on the new research, it is recommended to not leave your child with reflux sleeping in any car seat. Furthermore, if possible limit your traveling time to 1 hour or make sure to make frequent stops while traveling. Be very vigilant since this issue is very common among parents all over the world. Sitting baby more upright helps and keeping your baby in a rear-facing mode for as long as possible. Thinking to change the seat to a forward-facing unfortunately will not help your baby.
