While other brands may get the spotlight, Safety 1st is dedicated to providing high-quality yet affordable products for children and families. Safety 1st car seats meet or exceed industry standards for safety in construction, durability, and materials, while also providing a more accessible price point for some budgets.

Safety 1st uses a QuickFit Harness system which allows parents to adjust the headrest and harness in one easy step. There is no rethreading needed as your child grows. The harnesses also have an upfront adjustment so you can quickly change the fit around a coat, for example.

Parents who are concerned about the chemical composition of the car seats should rest easy knowing that the Safety 1st car seats are among the companies that use the least amounts of flame retardant materials in the car seat fabrics.

The NTSB requires manufacturers to include some fire retardant on all automotive upholstery, and Safety First uses only one component to meet this requirement.

Our research and thorough testing led to the conclusion that the Safety First Grow and Go Best 3-in-1 seat is the best choice for a Safety 1st brand car seat. This seat has excellent safety ratings and fits into most budgets. It is suitable for children 5-100 pounds.

In addition to exceptional safety and comfort for your child, this car seat has a machine washable cover and takes up less room in the back seat than other car seats providing both comfort and convenience for parents.

We have narrowed down our choices for Safety 1st car seats to the top 5. Read on for details and safety ratings about this practical and affordable line of car seats.

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 Amazon.com and the manufacturer’s website are included to give you a clear overall idea of how well the product functions. In addition, an 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.
