2025’s Safest Non-Toxic Car Seats That Aren’t Treated With Flame Retardants

Choosing a car seat is one of the biggest decisions you’ll make for your baby’s safety. We all want to feel confident knowing our little one is as protected as possible every time we leave the house. But here’s the thing most parents don’t realize: some of the “safest” car seats on the market can actually be loaded with toxic chemicals.

Most conventional car seats are treated with flame retardants and PFAS (forever chemicals) to meet outdated flammability rules. These substances might sound harmless, but they can release toxins into the air and dust your baby breathes, and they’ve been linked to hormone disruption, developmental delays, and other health issues.

The good news is that you don’t have to compromise between crash safety and chemical safety anymore. There are now non-toxic car seats that protect your child beautifully without the added chemicals.

In this guide, we’ll walk through what makes a car seat “non-toxic”, why avoiding flame retardants and PFAS matters, and which car seat brands are leading the way with cleaner, safer materials for your baby, toddler, or big kid.

Wondering what kind of car seat your little one needs? This chart will walk you through some of the main differences between each type of seat on this list.

2025 Infant Car Seats

Portable car seats that can attach to a stroller or car seat base.

Infant car seats are designed for newborns and smaller babies, usually from around 4–30 lbs. They’re always used rear-facing and typically click into a base that stays installed in your car or into a stroller, making them convenient for parents who are on the go. Some parents skip the infant car seat and start with an all-in-one or convertible car seat, but I personally prefer the convenience and portability of an infant car seat for the early months.

• Pros: Portable, lightweight, easy to install, compatible with travel systems (strollers).
• Cons: They have a pretty short lifespan; most babies outgrow them by 8–12 months.
• Best for: Newborns and families who want a removable carrier-style seat for errands and naps on the go.

2025 Convertible Car Seats

Rear or forward facing car seats that can be used from birth through toddlerhood.

Convertible seats can be used from birth and will grow with your child. They can be used rear-facing and then convert to forward-facing once your little one meets the height and weight requirements. Many allow for extended rear-facing use up to 40–50 lbs.

• Pros: Long-term use (infancy through toddlerhood), excellent value, higher safety ratings in extended rear-facing mode.
• Cons: Heavier, not portable, not ideal for transferring between vehicles frequently.
• Best for: Parents who want one seat to last multiple years and don’t need the portability of an infant bucket seat.

2025 All in One Car Seats

A car seat that can be used from birth through the big-kid years.

All-in-One car seats are designed to be the only car seat you’ll ever need, because they transition from rear-facing to forward-facing to booster mode.

• Pros: Excellent long-term value, convenient, fewer total purchases.
• Cons: Bulky, not ideal for small cars, and some all-in-ones compromise fit in one stage to accommodate all ages.
• Best for: Families who want one seat from birth through big-kid years and have space to accommodate a larger seat.

2025 Harness Booster Seats

The feel of a big kid booster seat with the safety features of a 5-point harness.

Harness Booster seats (also called combination seats) start out with a 5-point harness and later convert to a belt-positioning booster. They’re great for kids who have outgrown their convertible seat but still need extra security before using the vehicle’s seat belt.

• Pros: Longer use from toddler to big kid, strong side-impact protection, and easy installation in forward-facing mode.
• Cons: Forward-facing only; not suitable for infants or extended rear-facing.
• Best for: Preschoolers and young school-aged kids who meet the forward-facing weight and height minimums but still benefit from a harness for proper restraint.

2025 Boosters and Belt-Positioning Seats

Booster seats that help position the car’s safety belt. For big kids only.

Booster seats help position the car’s seat belt safely across your child’s chest and hips once they’ve outgrown a harnessed seat. High-back boosters offer extra head and torso protection, while backless boosters are more portable for older, taller kids.

• Pros: Promotes correct seat-belt fit, lightweight, easy to move between cars.
• Cons: Less containment than harnessed seats; relies on child’s ability to sit upright the whole ride.
• Best for: Kids at least 5 years old who meet height and weight requirements and are mature enough to stay properly positioned in a booster every ride.

Browse Car Seats by Brand

Research in recent years has shown that roughly 83% of car seats tested contain at least one type of flame retardant chemical, many of which have been linked to hormone disruption, developmental delays, and other health concerns. Thankfully, several brands are now proving that car seats can meet strict federal safety standards without relying on these chemicals.

Based on information disclosed by the manufacturers, the car seats listed below are made without the use of flame retardants in the seat fabric; some also do not contain these chemicals in the seat foam, and many are also free from PFAS and other harmful treatments. These brands are leading the way toward safer, cleaner baby gear that protects children both in the car and from unnecessary toxic exposure.

Nuna

All Nuna car seats made in 2020 or later are completely free from added flame retardant chemicals, in both the foam and the fabrics. The brand has fully phased out the use of flame retardants across its product line, making Nuna one of the cleanest and most trustworthy car seat brands available today.

Nuna meets federal flammability standards naturally, using Merino wool blends and carefully selected materials instead of chemical treatments. Each seat also has a GREENGUARD Gold certification, which means it’s been independently tested for thousands of chemical emissions and VOCs to ensure better air quality for your baby.

From their infant seats to convertibles and boosters, Nuna’s car seats are thoughtfully designed with quality, safety, and style in mind. The fabrics feel soft and premium, the designs are oh so sleek, and every detail reflects the brand’s commitment to cleaner, more sustainable materials. You can tell Nuna really prioritizes both safety and elegance for families; be sure to check out their beautiful strollers as well.

If you’re looking for a truly non-toxic car seat with the added safety features of a premium brand, Nuna is one of the best options out there.

Nuna’s Non-Toxic Car Seats

Shop Nuna Car Seats: Nuna can be purchased at select retailers and from Nuna directly. They can also be bought as part of a travel system, and their strollers are listed on our guide to non-toxic strollers. Nuna car seats occasionally go on sale during big holiday sale events.

UPPAbaby

UPPAbaby will always have a special place on this list because they were the first company to introduce a car seat completely free of flame-retardant chemicals. That’s a huge milestone in the world of baby gear and it truly set the standard for other manufacturers to follow. Their commitment to safer materials and thoughtful design has made UPPAbaby a long-time favorite on Gentle Nursery, and I have personally used their car seats and strollers for my babies.

Their products also stand out when it comes to style and functionality. Their car seats are sleek, easy to install, and thoughtfully designed to make life with a baby just a little simpler. I also love that they offer free virtual car seat checks with certified child passenger safety technicians; this is such a helpful resource for parents who want to make sure their seat is installed correctly and safely and I can say it helped me tremendously!

UPPAbaby makes a full range of car seats, from infant seats to boosters, and they offers several non-toxic fabric options to fit your preferences. SafeTech is their original fire-retardant-free fabric that’s GREENGUARD Gold certified, soft, and washable. DualTech takes it a step further with both fire-retardant-free fabrics and foams, woven to naturally meet safety standards without chemical treatments. And for the cleanest, most premium option, PureTech uses temperature-regulating, hypoallergenic Merino wool that’s naturally flame-retardant-free and moisture-wicking.

If you’re looking for a car seat that’s both non-toxic and easy to love, UPPAbaby continues to be one of the very best choices.

Clek

Clek is an innovative Canadian car seat manufacturer and one of the first brands to offer convertible car seats made without flame-retardant chemicals. Designed in Canada to meet rigorous European safety standards, Clek’s seats are built with exceptional attention to detail, featuring advanced side-impact protection, a steel and magnesium frame, and an anti-rebound bar for extra rear-facing safety. Their convertible seats also support extended rear-facing use up to 50 lbs (around age 4), which is a major plus!

Please note: only Clek car seats made with Ziip fabrics are made without the use of flame-retardant and PFAS chemicals. These fabrics are naturally flame-resistant, PFAS-free, and fluorine-free, without relying on chemical treatments. Clek’s Mammoth Ziip option, made from Merino wool, is also hypoallergenic, breathable, and naturally temperature-regulating, making it one of the cleanest and most comfortable car seat materials available. I personally had the Foonf in Mammoth and found it to be a beautiful, sturdy, and wonderful car seat.

It’s important to note that all other Clek fabrics do contain flame retardants, though the company avoids the most concerning halogenated and brominated types. To ensure you’re getting a non-toxic option, look specifically for the Ziip designation when shopping.

I personally love Clek’s wool car seats… they’re beautifully made, thoughtfully designed, and feel incredibly sturdy. While they’re not quite as easy to install as the Britax ClickTight models, they’re still a wonderful choice for families who prioritize non-toxic materials. The only real downside is that the Ziip wool fabric isn’t removable, so it can only be spot-cleaned.

And a fun bonus: Clek also offers a car seat recycling program, which is such a great initiative for sustainability-minded parents.

Britax SafeWash

Britax has long been a leader in car seat safety, and it’s exciting to see them take meaningful steps toward cleaner materials with their SafeWash line. While not all of their car seats have transitioned yet, many of the newer models now come in SafeWash fabrics — and these versions meet our criteria for non-toxic car seats.

SafeWash fabrics are completely free of chemical flame retardants, offering a much safer option for babies and toddlers. Britax achieves flammability compliance through tightly woven, high-performance fabrics rather than chemical treatments, so the seats are safe without relying on wool or additives.

Another parent-friendly feature: the seat covers are removable and can be washed in the washing machine, making cleanup easier (just be sure to follow Britax’s instructions and replace the cover as instructed).

When shopping for Britax, always look for the SafeWash label in the product name or description; those are the FR-free versions. Models without this designation may still use flame retardants, so double-check the fabric before purchasing.

Britax’s Non-Toxic Car Seats

Please note: at the time of publishing, the Skyline Belt-Positioning Booster seat was not available in Safewash fabrics and was therefore left off this list.

Shop Britax SafeWash Car Seats: Britax is available at big box stores and most retailers. Use the following links to check pricing and availability:

Chicco ClearTex

Chicco has made major strides toward safer materials with their ClearTex and ClearLux lines, which are completely free of added flame-retardant chemicals. These seats use innovative, tightly woven fabrics that naturally meet flammability standards without chemical treatments. Both ClearTex and ClearLux seats are also GREENGUARD Gold certified, meaning they’ve been tested for thousands of chemical emissions and VOCs to help support cleaner indoor air.

One of the best things about Chicco’s ClearTex collection is how accessible it is. The line includes several popular models, from infant seats to convertibles and boosters, at a more budget-friendly price point compared to many premium brands. Chicco seats are known for their easy installations, sturdy builds, and smooth functionality, making them a practical and reliable choice for most families.

If you’re shopping Chicco, make sure to look for the ClearTex or ClearLux label, as those are the versions that meet non-toxic standards. Other Chicco car seats may still use traditional flame retardants.

Babyark

Babyark is one of the newest entrants in the car seat market, and arguably the most advanced in safety engineering. Built with a steel frame, carbon fiber shell, and “egg-shaped” safety capsule design, Babyark seats are completely free of added flame retardant chemicals and PFAS. The brand meets all U.S. safety standards using natural wool-based fabrics and advanced energy-absorbing materials.

Their car seats are stunningly beautiful, and while they do come at a premium price, you will appreciate the sleek design and added safety features. Currently, the Babyark is only available in convertible models, but there are two versions: a smart car seat and a classic car seat. The While I have mixed feelings on using a smart carseat (there are both pros and cons that you can argue), Babyark’s companion app provides installation guidance, making setup incredibly straightforward.

Evenflo

Evenflo has been around for decades and is known for producing affordable car seats with solid safety features and broad availability. Recently, they’ve made strides toward cleaner manufacturing through their Green & Gentle collection, which uses fabrics made without added flame retardant chemicals. These seats meet flammability standards naturally, making them a safer choice for families who want a lower-tox option on a budget.

That said, Evenflo’s newer models are increasingly tech-heavy, with built-in features like SensorSafe (which monitors temperature, harness status, and vehicle movement) and SensorSoothe (which plays white noise, lights, or lullabies to calm your baby). While these can sound appealing, they add complexity and electronic components that many parents (especially those of us who prefer simple, natural products) find unnecessary. In my opinion, the technology often feels over-engineered for what could have been a straightforward, mechanical safety device.

Still, Evenflo deserves credit for making non-toxic fabrics more accessible at lower price points. Just make sure you’re selecting a Green & Gentle model, as their other fabric lines may still contain conventional flame retardants or chemical finishes.

How to Choose the Right Car Seat for Your Child

Choosing the right car seat for your baby can feel overwhelming. There are so many options and safety features to compare. The good news is that every car seat sold in the United States must meet the same federal crash safety standards, so your main job is finding one that fits your child, your car, and your lifestyle, and ideally, one that’s free from harmful chemicals. Bottom line: the safest seat is the one that fits your child and your vehicle and is installed and used correctly every ride; brand or price comes after that

There are two main aspects to think about when shopping for a car seat: physical safety and chemical safety.

Step 1: Prioritize Physical Safety

Your baby’s physical safety always comes first. Even the best-rated car seat can’t protect your child properly if it doesn’t fit your vehicle or isn’t installed correctly. When comparing options, pay attention to:

• Manufacturer reputation: Stick with trusted brands known for quality and customer service. All car seats must pass federal safety testing, but some companies go above and beyond with stronger materials, better side-impact protection, or easier installation systems.
• Fit and limits: Always check the car seat’s height and weight limits to make sure it’s appropriate for your child’s current size, and know your state’s car seat laws as they grow.
• Ease of installation: Your car seat should be easy for you to install correctly every time. If the base feels loose or you struggle to tighten the harness, it’s not the right seat for your vehicle. Some seats like Britax ClickTight have tensioning systems that make secure installs much simpler. If you’re unsure about your install, get a quick check from a Child Passenger Safety Technician (CPST); I always do this when installing a new car seat!
• Crash test and NHTSA ratings: The National Highway Traffic Safety Administration (NHTSA) publishes car seat safety ratings and ease-of-use reviews that can be helpful when comparing models. Just remember that all U.S. seats meet baseline safety standards, but it’s important to note that these crash test results vary from car to car. So while these are helpful to consider, they shouldn’t be your only deciding factor when buying a car seat.
• Rear-face your child as long as possible. Rear-facing is safer for your child in the event of a collision. While each state has its laws about rear-facing, the American Academy of Pediatrics (AAP) now advises parents to keep their children rear-facing as long as possible, not just until age 2. In fact, age 2 is now considered a minimum, not a stopping point. The safest position for babies and toddlers is rear-facing until they reach the maximum height or weight allowed by their seat, which for many convertible seats can mean age 3, 4, or even older. What matters most is your child’s fit within the car seat, not their age alone. All children under 13 should ride in the rear seat for optimal protection.

Some added safety features that you might want to look for include:

• Side-Impact Protection: Extra energy-absorbing foam or pods that protect your child’s head, neck, and torso in a side collision.
• Load Leg: A stabilizing bar that extends from the base to the vehicle floor, reducing crash forces and limiting seat rotation.
• Anti-Rebound Bar: A bar that is positioned at the foot of the car seat that is designed to prevent the car seat from rebounding toward the back seat after a frontal crash, improving stability.
• Rigid LATCH Connectors: Provide a secure, tight installation and reduce movement compared to flexible strap connectors.
• Energy-Absorbing Base or Crumple Zone: Designed to absorb crash energy before it reaches your child, similar to your car’s crumple zone.
• Top Tether: Anchors the top of a forward-facing car seat to the vehicle and can significantly reduce head movement in a crash.
• Steel-Reinforced Frame: Adds strength and durability to the seat’s structure for greater crash protection.
• No-Re-Thread Harness: Lets you adjust the harness height easily as your child grows, ensuring a proper fit every time.
• Enhanced Side Wings or Deep Shell Design: Surrounds the child in protective cushioning for better head containment during impact.
• Integrated Belt Tensioning System: Makes installation easier and safer by automatically tightening and securing the seatbelt path.
• Sensor or Indicator Systems: Some models include visual or digital alerts to confirm correct installation or harness tightness.

Step 2: Factor in Chemical Safety

Now, take a closer look at what’s in the seat itself. Many conventional car seats still rely on chemical treatments to meet outdated flammability or stain-resistance claims. These additives can off-gas into your car or provide unnecessary exposure directly through the skin for babies who spend hours buckled in each week.

Here are the most common chemicals of concern in car seats, and why they’re best avoided:

Flame Retardants
These are added to the seat’s foam and fabric to meet federal flammability requirements that date back to the 1980s. Many flame retardants—especially halogenated and chlorinated types—have been linked to hormone disruption, thyroid imbalance, and developmental issues. They don’t just stay contained in the seat, either; they slowly break down and collect in vehicle dust that babies breathe or touch. Because babies’ bodies are still developing, even low-level exposure can be more harmful over time.

Many brands have shifted to phosphorus-based flame retardants in place of halogenated ones, labeling them as “safer.” While they may break down faster in the environment, early research shows they can still interfere with brain and hormone development.

PFAS (Perfluorinated “Forever Chemicals”)
PFAS chemicals give fabrics their stain-, water-, and grease-resistant properties, but they come with serious downsides. They persist in the environment and the human body for years, accumulating over time. Exposure has been associated with immune suppression, thyroid disorders, reproductive harm, and certain cancers. PFAS can migrate out of treated materials and into car dust, making them especially concerning for infants and toddlers.

Heavy Metals
Metals such as lead, antimony, and cadmium can appear in dyes, pigments, or seat hardware. These are potent neurotoxins that can affect brain growth, attention, and behavior, even at trace levels. While reputable manufacturers test for heavy metals, lower-cost or off-brand products may not.

PVC (Polyvinyl Chloride)
PVC is a plastic sometimes used in trim or piping. It contains chlorine and can release dioxins or phthalates, both known endocrine disruptors. Over time, exposure to PVC and its additives has been linked to respiratory irritation, hormone imbalance, and reproductive toxicity. Choosing car seats and accessories that are PVC-free helps reduce your child’s exposure to these harmful compounds.

Antibacterial Agents (like Triclosan)
Antimicrobial finishes may sound appealing, but they’re unnecessary in baby gear and can actually do more harm than good. Chemicals like triclosan have been shown to disrupt hormone function and contribute to antibiotic resistance. Some car seat covers are removable and washable, so if this is important to you, look for this in a car seat (such as Chicco Zip seats).

The Bottom Line?
These chemicals were originally added to improve performance or meet safety regulations, but they’re not essential, and they can expose babies to toxins linked to hormonal and developmental disruptions during a critical stage of development. Babies and toddlers spend a lot of time in their car seats, so choosing one made with safer materials can make a meaningful difference.

The good news is that more brands are now using inherently flame-resistant materials (like wool or tightly woven polyester) and eliminating PFAS coatings altogether. Companies like UPPAbaby, Nuna, Britax, Clek, Babyark, and Chicco have proven it’s possible to meet safety and flammability standards naturally. Plus, many of the car seats we’ve listed hold certifications from third-party bodies like OEKO-TEX and GREENGUARD, among others.

Toxic Chemicals Found in Child Car Seats

Much of this information about harmful chemicals in children’s car seats came to light thanks to testing in recent years done by The Ecology Center. Thanks to their studies on car seat toxicity, we know the following:

• 83% of car seats tested contain flame-retardant chemicals that may be hazardous.
• 50% of the seats tested contain PFASs and the Ecology Center indicates that these chemicals are unnecessary.
• Since their studies began, PBDEs and Chlorinated Tris have been phased out by manufacturers.
• Not enough testing is being done on the chemicals that are used in car seats.
• Three car seat manufacturers (Britax, Maxi Cosi, and Chicco) make seats with removable, washable covers to help avoid the need for PFAS chemicals for stain resistance.

You Might Still Be Wondering Why Flame Retardant Chemicals are Concerning

While car seats are made for children, they are subject to automotive regulations (which were last updated in 1981).

All car seats sold in the United States must meet federal motion vehicle flammability regulation FMVSS 302 to reduce injuries in the event of a vehicle fire. In theory, this is a worthy idea. 

However, many manufacturers use low-cost halogenated flame retardant chemicals to meet these standards. There are three major problems with this:

Problem #1: These flame retardant chemicals are associated with numerous health risks.

Exposure to halogenated (brominated or chlorinated) flame retardants has been associated with a wide range of impacts on animals and humans. These include immunotoxicity, reproductive toxicity, endocrine disruption, impairment of fetal and child development, interference in thyroid, liver, and neurological function, and cancer. 

Because of how flame retardant chemicals are applied to the foam and fabric of car seats, they break down and can be present in the air and dust inside vehicles. Babies and children can become exposed to these chemicals through ingestion dust, inhalation, or physical contact.

While cars themselves aren’t free of flame retardant chemicals, this is concerning considering how much time children spend in their car seats and how sensitive their systems are. Car seat companies are exposing babies to these chemicals in their car seats, an item kids make regular and direct contact with, often for prolonged periods.

Problem #2: Flame retardant chemicals may not even be necessary in the event of a fire.

The National Highway Traffic Safety Administration (NHTSA) itself can’t justify the use of these flame-retardant chemicals. The NHTSA “never evaluated the effectiveness of the federal motor vehicle standard in children’s car seats. The agency also said it was unaware of any records, data or studies that indicate the current flammability standard is relevant or provides any fire safety benefit in a child’s car seat.” 

Problem #3: These chemical fire retardants may be ineffective.

There is no evidence that many of the flame retardant chemicals companies are using to meet these flammability standards provide any safety benefit in the event of a fire. In fact, there is widespread concern that these regulations are exposing children to more harm and health hazards. Flame retardants emit carcinogens when they burn. Additionally:

Flame retardants may also contribute to injury when they burn. For example, when foam containing pentaBDE burned, it produced twice as much smoke, seven times as much carbon monoxide, and 70 times as much soot as foam without flame retardants.

And that’s just the tip of the iceberg. But, this is still the current law, and car seat manufacturers must continue to meet these standards.

There is some good news, though.

Manufacturers can meet automobile flammability standards without using toxic flame retardants. Thanks to consumer demand, companies are making car seats that contain no flame retardant chemicals at all, and there are many more who use phosphate-based chemicals instead of halogenated flame retardants. (Phosphate-based flame retardants are believed to be somewhat safer than chlorinated and brominated chemicals at this time, though further studies are still needed to prove their safety.)

Why Should You Avoid Perfluorinated Chemicals?

PFAS is a family of harmful chemicals that includes perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). These chemicals are used in many products, including food packaging, non-stick cookware, and stain-resistant fabrics. They’re also found in some car seats. Studies have linked PFAS exposure to cancer, thyroid problems, reproductive issues, and other health problems. 

Additionally, thanks once again to the Ecology Center, there is more transparency regarding the use of perfluorinated chemicals (PFCs/PFOAs) in car seats. These chemicals are stain, water, and grease-repellant treatments that are used as fabric treatments on many car seats. They’re also used to make non-stick cookware.

These chemicals have been linked to human health hazards and have been shown to have the following effects in animal studies:

• disrupt normal endocrine activity
• reduce immune function
• cause adverse effects on multiple organs, including the liver and pancreas
• and cause developmental problems in rodent offspring exposed in the womb.

Ideally, we would want to avoid exposure to these chemicals whenever possible – especially direct contact.

Manufacturers Are Now Making Car Seats Without Flame Retardants and PFAS

Chemical flame retardants are unnecessary but inexpensive. That’s why most car seat manufacturers use them. But, there’s a better way: by using inherently flame-resistant fabrics such as wool and tightly woven polyester, manufacturers can still meet flammability standards without the use of chemical flame retardants.

In fact, since the Ecology Center first began studying car seat toxicity, a whopping 13 car seat manufacturers in the United States have introduced car seats without flame retardants. This is a huge advancement, and I am so happy to see that manufacturers are doing better for our babies.

The list here is a complete list of all car seats without flame retardant chemicals that are available in the United States. Please note that while these car seats do not contain flame retardant chemicals, they still contain polyurethane foam used as padding. At this time to my knowledge, no car seat manufacturers are using an alternative to polyurethane foam or even Certi-Pur foam.

To be certain that you are buying a car seat without flame retardant chemicals, please note the exact car seat model, fabric, and colors listed in this article. The links should take you to the right model, but please double-check before ordering your car seat because links and fabric options change.

Coming Soon: New Federal Side-Impact Protection Standards
Beginning December 5, 2026, all new child car seats sold in the U.S. will be required to meet updated federal crash-test standards (FMVSS 213a) that include side-impact testing. This regulation ensures that new seats can better protect children’s heads and chests in T-bone or side-collision crashes. If you’re buying a seat before that date, it’s still perfectly safe to use if it meets current federal standards—but newer models released after 2026 will include this enhanced layer of protection.

What if Your Car Seat Contains Flame Retardants?

Don’t stress if your car seat is not on this list of recommended car seats. If you own a car seat that was made with these chemicals, here’s my advice:

• Don’t keep your baby in the car seat longer than necessary. When removing your baby from the car, hold your baby or switch to a baby carrier or into the stroller seat. Cutting down on your baby’s use and time spent in the car seat will help.
• Wash the fabric regularly. If (and only if) your car seat fabric can be washed, wash it often per the manufacturer’s washing instructions. You can also leave the seat outside in the sun for a couple of days to speed up the off-gassing of chemicals, though flame retardant chemicals are unlikely to be washed out.
• Vacuum your car and car seat regularly. Use a handheld HEPA vacuum to clean the inside of your car regularly. Also, keep a microfiber cloth in your car to wipe down any settled dust because dust is one avenue for exposure to these chemicals.
• Consider replacing the car seat.
  • Ask yourself how long you’ll be using it? I would advise you to consider how long you will use the car seat before replacing it. For example, if it is an infant car seat and you will be moving up to a convertible car seat within a couple of months, you would probably not need to replace the infant car seat. (However, in this situation you might want to switch to the convertible car seat sooner than you would have otherwise.)
  • How much would it cost to buy a non-toxic car seat? Keeping your budget in mind, does switching to another car seat make sense?

A Final Word About Non-Toxic Car Seats

In the words of Jeff Gearhart, research director at the Ecology Center: “Manufacturers who continue to produce seats with toxic flame retardants are going to be seen as dinosaurs.”

The future of baby gear is non-toxic.

It might start with organic crib mattresses and non-toxic car seats and avoiding chemicals while you’re pregnant, but the truth is that babies should not be exposed to toxic flame retardants and PFAS and other toxic chemicals.

It’s time for ALL car seat manufacturers to step up. 

We as parents don’t want to expose our children to unnecessary chemicals that have an array of health hazards including hormone disruption, health risks, mental impairment, or reproductive damage.
