The decision to transition your child from their infant car seat to a convertible car seat or an all-in-one car seat (these are like convertible car seats but have the added feature of being able to transform from a rear-facing car seat to a forward-facing one and a booster seat) can be overwhelming. With so many different car seats on the market, it can be difficult to choose which one is right or what features to look for. 


Choose The Safest Convertible Car Seat Without Toxins

You need to find a convertible car seat that provides your baby with physical safety (reduces the risk of death or injury in car accidents) and chemical safety (made of materials that don’t contain toxins, carcinogens, or hormone disruptors).

In the USA, most car seats are still filled with toxic chemical flame-retardants. Currently, only a few companies manufacture baby car seats without these chemicals, so we will provide you with Our Full List Of Non-Toxic Convertible Car Seats that are available now.


Why Is It Important To Choose A Non-Toxic Car Seat For Your Baby?

Young children and infants are particularly susceptible and sensitive to toxins compared to adults because their bodies are still developing, they are less able to detoxify their bodies, and they have more surface area on their skin that toxins can penetrate [1].

Due to this, research has discovered that children have higher concentrations of flame retardants in their bodies than adults. 

Therefore, we need to limit children’s exposure to chemicals that can negatively impact their health now and in the future.


What Makes A Car Seat Potentially Toxic?

Car seats can be made potentially toxic by flame retardants and PFAS. 

1. Flame Retardants

Most children’s car seats, to adhere to Federal Motor Safety Standard 302’s flammability requirements, are treated with dangerous flame retardants. 

Children can make direct skin contact or inhale these retardants. Evidence indicates that using them can cause health problems such as immune system problems, endocrine and thyroid disruption, reproductive toxicity, developmental problems, cancer, and neurological problems [2]. 

The brands we recommend in our article adhere to federal flammability requirements, using materials that are flame-resistant without using dangerous chemicals.

2. PFAS

PFAS refers to a group of human-made chemicals that includes PFOA, PFOS, GenX, and many others [4] that are used to make car seats waterproof. 

Evidence suggests that the use of these chemicals can cause health problems such as reproductive issues, developmental delays, kidney and liver problems, immune system problems, and tumors [5]. 

They can be absorbed through sweat, and there is a research which states that sunlight can increase the levels of these chemicals in car seats. 


What is a Convertible Car Seat? 

A convertible car seat (some parents call it ‘toddler car seat’) is a car seat that can be installed both rear-facing for infants, then turned forward-facing for larger and older children. These car seats adapt to your child’s growth. 

A convertible car seat can take your child from infancy to preschool years and beyond (some convertible car seats can turn into a booster seat for school-age children). But we do recommend starting your newborn baby journey with an infant car seat because they are made specifically to keep newborns and infants safe and comfortable while traveling.


When Do You Need A Convertible Car Seat?

Some parents will choose an infant car seat initially and then transition to a convertible car seat when their baby has reached the infant car seat’s height or weight maximum (32 inches tall and 30-35lbs), but other parents will use a convertible car seat straight away. 

Statistics show that, on average, babies transition from an infant car seat to a convertible seat starting at about 9 to 12 months old.


Advantages of Convertible Car Seats

We found the next benefits of using convertible car seats:

  1. These seats offer you the ability to switch the seat from a rear-facing position to a front-facing one and vice versa. This helps accommodate your child’s growth while making sure they stay safe.
  1. These seats can be used for the duration of at least 4 years and up to 6 years. 
  1. Cost is an advantage because starting out with a suitable convertible seat instead of an infant car seat allows you to buy just one seat instead of two. Depending on the size of your child, a convertible car seat may be used from when they are a newborn until they’re a toddler.

Disadvantages Of Convertible Car Seats

Convertible seats can also have some disadvantages, such as the following:

  1. If you choose a convertible car seat for your newborn or infant, keep in mind that it won’t click into a stay-in-car base or strollers.
  1. These seats are often bulkier than infant car seats, so they’re not especially portable, meaning that they cannot be quickly taken out of the car once installed. 

What To Look For In A Non-Toxic Convertible Car Seat?

Here are some things you’ll want to look for when searching for the best non-toxic convertible car seat for your little one:

1. Car Seat Safety 

All car seats on the market go through strict testing and must follow all safety regulations. All of them are considered safe since safety is inherent to car seats. 

However, some car seats perform better in crash tests, and some companies may include added safety features to their car seats that are not required by law.

2. Materials Used

Always pay attention to the materials your car seat is made of. It is important to avoid infant car seats that have fabric treated with flame retardants and PFAS chemicals. 

Being on the lookout for GreenGuard Gold Certification is a good idea. GreenGuard Gold Certification helps to identify healthier baby products! You might have heard about other concerning toxins in car seats, including phthalates, PVCs, heavy metals, formaldehyde, and more. Fortunately, you can look for the GREENGUARD Gold Certification on the convertible car seats that will ensure that they have been tested for it, and they are safer for your baby.

3. Size

Try to choose a car seat that will easily fit into your car.

4. Higher Rear-Facing Weight Limits.

Evidence indicates that rear-facing seats are safer for babies and children. If you can, select a convertible car seat with a high rear-facing weight limit so you can use a rear-facing seat for as long as possible.

5. Car Seat Cost

Some car seats are cheaper not because they are unsafe but because they may be made without any extras or additional safety features not required by law, whereas more expensive car seats have eco-friendly fabrics or a stability leg for extra support in the event of a crash. Fortunately, it is much easier today than it was in the past to find a less expensive but still non-toxic and high-quality car seat.

  • This car seat is designed for children from 5 to 65 lbs (Rear Facing: from 5 to 50 lbs; Forward Facing: from 25 lbs to 65 lbs). The height limit is 49”.
  • RAVA car seats have great crash test scores and go above legally required safety standards in the US. They include energy-absorbing foam and SIP (Side-Impact Protection) pods, which is important because statistics suggest that children suffer worse injuries in side-impact collisions.

Something To Keep In Mind
