Much like the Clek Oobr, this convertible seat is made of merino wool fabric. It’s naturally flame and stain-resistant, and it works great for different climates!

What we love about the Fllo is how COMPACT it is! It’s narrow enough that you can fit three of these in the back seat!

Types of Car Seats

Non-Toxic Car Seats_Types of Car Seats

There are three main types of car seats you would see in the market. Take a look and see which type will work best for you and your children.

Infant Car Seats

From the name itself, this car seat type is meant for infants. In terms of weight, most of these car seats accommodate babies weighing within 4 to 35 lbs.

Infant seats have a lower recline design that’s meant for infants, and these are meant to be rear-facing. Rear-facing would mean your little one is facing the back of the car.

This is recommended for infants because, in case of an accident, a rear-facing position would absorb more impact from a crash. This will protect your developing baby’s head, neck, and spine that a front-facing car seat wouldn’t be able to give!

Convertible Car Seats

A convertible car seat gives the most value out of all the car seats. Convertible car seats are designed to adapt and grow with your baby. These can work for infants and toddlers!

There are different kinds of convertibles, but the most versatile ones are the all-in-one convertibles. These can hold infants up to toddlers that weigh 120 lbs!

Booster Seats

If you already have full-grown children that have outgrown their infant or convertible car seats, then a booster seat is what you should look for.

These car seats are bigger and designed for older children. If you ask us, buying an all-in-one convertible would be best for long-term use.

Although, if you weren’t able to buy a convertible car seat right from the beginning, then it’s not too late to pick up a great booster seat for their safety!

Plus, for whatever car seat type you choose, just be sure you know the right techniques on how to keep your infant cool in his car seat. Sometimes babies can get fussy so it’s best to keep them comfortable.

Flame Retardant Chemicals in Car Seats

Non-Toxic Car Seats_Flame Retardant Chemicals in Car Seats

Like what we mentioned before, it was common for flame retardant chemicals to be used on car seats. To add more context, this is because of regulations that required companies to test their products for flammability.

This anti-flammability test isn’t so great for moms who are concerned about the harmful effects flame retardants can give children.

For the past few years, car seat companies tried to deal with this by using naturally flame retardant materials like wool. Some use synthetic materials like polyester too. Not only are these materials safe for babies, but they pass flammability tests as well!

This is a great step in the right direction for future infant car seats, and hopefully, more companies can follow suit!

Ecology Center

The research on car seat flame retardant chemicals just keeps growing, and it’s thanks a lot to the Ecology Center!

They review, test, and contact different companies if their non-toxic car seats are truly non-toxic and free of flame retardants.

If your car seat isn’t on their list, then that means at least one kind of flame retardant chemical is present. What should you do if your current car seat isn’t on their list?

The best course of action is to buy a non-toxic car seat to replace your older car seats. Although, we understand how expensive these car seats can be. Not all of them are usable for a long time too!

If buying new car seats is out of the question, then we suggest regularly cleaning your child’s car seat or avoid exposing it to heat.

This won’t get rid of the chemical flame retardants present in the car seat, but it can help reduce its harmful effects from reaching your children.

Aside from the Safety 1st Grow and Go 3-in-1 Car Seat, which has one component with phosphate-based flame retardant chemicals, all other car seats in our list can be found in the Ecology Center Flame Retardant-Free Car Seats list.

That should ease your mind and make things easier for you to pick the best non-toxic car seat for you.

What Are Flame Retardants?

A lot of baby products use chemical flame retardants for different kinds of baby essentials.

To avoid these flame retardant chemicals from affecting your children, buying organic or non-toxic baby products would be best.

There are two main types of flame retardant chemicals:

  • One being toxic halogenated flame retardants, which brominated and chlorinated-based flame retardants fall under. These are considered to be the most toxic flame retardants.
  • The other type would be non-halogenated flame retardants, which phosphate and nitrogen-based flame retardants would fall under. These are supposedly safe compared to halogenated ones, but there’s still some cause for concern.

Added flame retardants are a big no-no for children because of several health hazards that have been linked to them!

The most common flame retardant is TDCPP, a chlorinated-based flame retardant. This flame retardant has been linked to cancer and was actually banned from being used on children’s pajamas in 1977.

Flame retardants have also been linked to endocrine disruption, neurological problems, and your child’s overall development!

Best Practices to Deal With Flame Retardants

Flame retardants are still present in a lot of products like furniture, electronics, and cars. These toxic flame retardants usually leach out into the environment and can be harmful to your baby.

Babies usually inhale flame retardants when they break down into dust. They can also ingest them orally from objects they put in their mouths, like pacifiers.

It’s IMPOSSIBLE to completely protect your babies from flame retardants. The best thing we can do as parents is to make sure we reduce the chances of exposure as much as possible.

Flame retardants usually leach out from products faster when mixed with heat.

If it’s the summertime or if you’re in a hot climate, avoid leaving car seats and other baby products inside the car. If your car is parked outside your home, it would be best to store these inside your house instead.

If you parked your car outside somewhere else, stroller-compatible car seats or a spacious diaper bag to keep your baby products would be best.

These would ensure that no products are left and exposed to heat inside the car.

Of course, if you end up buying any of the car seats listed above, you don’t have to worry about any of these chemicals harming your baby.

Just be sure to also note in your Baby Preparation Checklist to steer clear from flame retardants for your other items.
