Where to Sell Used Car Seats

Selling used car seats can be a smart way to recoup some of your investment while helping other families save money. However, it’s crucial to choose the right platform, ensure the seat is safe and legal to resell, and price it fairly to attract buyers.

If you’ve recently upgraded your child’s car seat or are preparing for a new baby, you might be wondering what to do with your old one. Car seats aren’t exactly easy to store—they’re bulky, take up space, and often sit unused for years. Rather than letting it collect dust in the garage or tossing it in the trash, selling your used car seat is a practical and eco-friendly solution. Not only can you make some extra cash, but you’re also helping another family access a high-quality seat at a lower cost.

But before you list it online or post it in your neighborhood group, it’s important to understand the ins and outs of selling used car seats. Unlike toys or clothing, car seats are safety-critical devices. Buyers need to trust that the seat is safe, functional, and hasn’t been compromised in any way. That means you’ll need to be upfront about its history, condition, and expiration date. The good news? There are plenty of safe, legal, and effective ways to sell a used car seat—whether you’re looking for a quick local sale or a broader online audience.

In this guide, we’ll walk you through everything you need to know about where to sell used car seats, from choosing the best platforms to pricing your seat fairly and ensuring a smooth transaction. Whether you’re selling a rear-facing infant seat, a convertible model, or a booster, we’ve got you covered. Let’s dive in and turn that unused car seat into cash—safely and smartly.

Key Takeaways

• Safety first: Only sell car seats that are not expired, damaged, or recalled—check the manufacturer’s website for recall info.
• Know your market: Parents and caregivers are the primary buyers, so highlight safety features, age, and condition clearly.
• Choose the right platform: Options include Facebook Marketplace, eBay, local parenting groups, and consignment stores.
• Price competitively: Research similar listings and price your seat at 40–60% of the original retail value, depending on condition.
• Be transparent: Disclose any past accidents, cleaning history, and whether the seat was ever in a crash.
• Include accessories: Bundling with bases, cup holders, or travel bags can increase appeal and value.
• Local sales preferred: In-person transactions reduce shipping risks and allow buyers to inspect the seat firsthand.

Why Selling Used Car Seats Makes Sense

Car seats are among the most expensive items new parents buy. A high-end convertible seat can cost $300 or more, and many families go through two or three seats as their child grows. Once the child outgrows it, the seat often sits unused—sometimes for years. Selling it not only frees up space but also recoups some of that investment. Plus, it’s a sustainable choice. Instead of ending up in a landfill, your seat can serve another child safely.

Another reason to sell? Many parents are on tight budgets and appreciate affordable, gently used options. A well-maintained seat from a trusted brand like Graco, Chicco, or Britax can be a huge money-saver for a new family. By selling yours, you’re helping someone else while doing something good for the environment.

But there’s a catch: not all used car seats are safe to sell. The National Highway Traffic Safety Administration (NHTSA) advises against using seats that have been in a moderate to severe crash, are expired, or have missing parts. That’s why it’s essential to assess your seat honestly before listing it. If it meets safety standards and is in good condition, selling it is not only allowed—it’s encouraged.

Where to Sell Used Car Seats: Top Platforms and Marketplaces

When it comes to selling used car seats, you have several options—each with its own pros and cons. The best choice depends on your goals: do you want a quick local sale, a higher price, or maximum exposure? Let’s explore the most popular platforms.

Facebook Marketplace

Facebook Marketplace is one of the most convenient places to sell a used car seat. It’s free, easy to use, and connects you directly with local buyers. You can post photos, describe the seat’s condition, and message interested buyers instantly. Plus, since it’s location-based, you can arrange a safe, in-person pickup.

To get the best results, create a detailed listing. Include clear photos from multiple angles, mention the brand, model, and age of the seat, and note any included accessories like the base or sun canopy. Be sure to highlight that the seat has never been in an accident and is not expired. Many parents feel more comfortable buying locally so they can inspect the seat before purchasing.

eBay

eBay offers a wider audience than local platforms, which can help you get a better price—especially for high-end or hard-to-find models. You can choose between auction-style listings or “Buy It Now” options. However, shipping a car seat can be tricky. They’re heavy and bulky, which means shipping costs can eat into your profit.

If you go the eBay route, consider offering local pickup as an option. Or, if you must ship, use a sturdy box and insure the package. Clearly state in your listing whether shipping is included or extra. Also, be prepared to answer questions about the seat’s history and condition.

Local Parenting Groups and Buy/Sell/Trade Pages

Facebook groups dedicated to parenting, baby gear, or local communities are goldmines for selling used car seats. These groups are filled with parents actively looking for affordable, safe gear. Join groups in your city or region and follow their posting rules—many require you to introduce yourself first or post in a specific thread.

These groups often foster trust and community, so buyers may be more willing to meet in person. You can also ask for recommendations or referrals, which can boost your credibility. Just remember to be responsive and polite—word travels fast in parenting circles!

Consignment Stores

Some baby and children’s consignment stores accept used car seats, though policies vary widely. Stores like Once Upon a Child or local boutiques may take them on consignment, meaning they sell the seat for you and take a percentage of the sale. This is a hands-off option, but you’ll likely get less money than selling directly.

Call ahead to check their requirements. Many stores won’t accept expired seats or those with recalls. They may also require the original manual and proof of purchase. If your seat meets their standards, this can be a hassle-free way to sell.

Craigslist and OfferUp

Craigslist and OfferUp are other local options similar to Facebook Marketplace. They’re free or low-cost and allow you to reach nearby buyers. However, they may attract more scams or lowball offers, so use caution. Always meet in a public place, bring a friend, and avoid sharing personal information.

OfferUp has a built-in messaging system and user ratings, which can help build trust. Craigslist is more anonymous, so be extra vigilant. In both cases, clear photos and a detailed description are key.

How to Prepare Your Used Car Seat for Sale

Before you list your car seat, take the time to clean and inspect it thoroughly. A well-prepared seat not only looks better but also reassures buyers that it’s been well cared for.

Clean the Seat Properly

Start by removing the cover and washing it according to the manufacturer’s instructions. Most covers are machine washable, but avoid bleach or harsh detergents. Let it air dry completely—never put it in the dryer, as heat can damage the fabric.

Wipe down the plastic shell with a mild soap and water solution. Avoid spraying water directly onto the seat, especially near the harness or buckle. Use a soft cloth to clean hard-to-reach areas. If there are stains, try a baking soda paste or a fabric-safe cleaner.

Don’t forget the harness straps! They should be clean and free of fraying or damage. Never use chemicals on the straps, as they can weaken the material. If the straps are dirty, wipe them gently with a damp cloth.

Check for Damage and Recalls

Inspect the seat carefully for cracks, fading, or broken parts. Look at the buckle, harness, and adjustment mechanisms. Make sure everything moves smoothly and locks securely.

Check the expiration date—usually found on a label on the side or bottom of the seat. Most car seats expire 6 to 10 years from the manufacture date. Never sell an expired seat.

Next, verify that the seat hasn’t been recalled. Visit the NHTSA website or the manufacturer’s site and enter the model number and manufacture date. If it’s under recall, do not sell it—even if it seems fine. Safety comes first.

Gather Accessories and Documentation

Include any original accessories like the base, travel bag, cup holders, or sun canopy. These add value and make your listing more attractive. If you still have the instruction manual, include it—many buyers appreciate having the guide.

If you’ve lost the manual, you can often download a copy from the manufacturer’s website. Mention this in your listing so buyers know they can access it.

Pricing Your Used Car Seat Fairly

Pricing a used car seat can be tricky. You want to get a fair return, but you also need to be realistic. New parents often compare prices, so overpricing can lead to a long listing time.

Research Comparable Listings

Start by searching for the same or similar model on Facebook Marketplace, eBay, or local groups. Note the prices, condition, and included items. This will give you a benchmark.

As a general rule, price your seat at 40–60% of the original retail price, depending on age and condition. A seat that’s 1–2 years old and in excellent shape can fetch closer to 60%. One that’s 4–5 years old or shows wear should be priced lower.

Factor in Condition and Features

A seat with minimal wear, all original parts, and no recalls can command a higher price. If it’s been in a minor fender bender—even if it wasn’t installed—disclose it and reduce the price accordingly. Buyers will appreciate the honesty.

High-demand features like side-impact protection, no-rethread harness, or machine-washable covers can also justify a higher price. Mention these in your listing.

Consider Bundling

If you have other baby gear—like a stroller, diaper bag, or travel system—consider bundling them with the car seat. A “baby travel set” can attract buyers looking for a complete package and may increase your total sale price.

Safety and Legal Considerations

Selling a used car seat isn’t just about making money—it’s about ensuring child safety. There are legal and ethical responsibilities you must follow.

Never Sell a Recalled or Expired Seat

It’s illegal to sell a car seat that’s been recalled or is past its expiration date. These seats may have hidden defects or degraded materials that compromise safety. Always check the NHTSA database before listing.

Disclose Accident History

If the seat was ever in a car accident—even a minor one—you must disclose it. The NHTSA recommends replacing any seat involved in a moderate to severe crash, as internal damage may not be visible. Even if the seat looks fine, the structural integrity could be compromised.

Be honest in your listing. Say something like, “This seat was in a minor parking lot incident but was not occupied. I replaced it as a precaution, but I’m disclosing it for transparency.” Most buyers will appreciate the honesty and may still consider it, but they’ll make an informed decision.

Follow Platform Rules

Some platforms, like eBay, have specific policies about selling used car seats. They may require you to include safety disclaimers or prohibit certain models. Read the terms of service to avoid having your listing removed or account suspended.

Tips for a Smooth and Safe Transaction

Once you’ve listed your seat, the next step is closing the sale. Here’s how to make it go smoothly.

Respond Quickly to Inquiries

Parents often need car seats urgently—especially if they’re expecting or traveling. Respond to messages within 24 hours. Answer questions clearly and provide additional photos if requested.

Arrange Safe Meetups

For local sales, meet in a public place like a police station parking lot, mall, or busy store. Bring a friend if possible. Avoid meeting at your home, especially if you’re alone.

Let the buyer inspect the seat before payment. They may want to check the harness, buckle, and expiration date. This is normal and shows they’re being responsible.

Accept Secure Payment Methods

Use cash, Venmo, or PayPal Goods and Services for payment. Avoid wire transfers or gift cards, which are common in scams. If using PayPal, make sure to select the “Goods and Services” option for buyer/seller protection.

Provide a Receipt

Even for a used item, a simple receipt with the date, item description, and price can build trust. It also protects you in case of disputes.

Alternatives to Selling: Donating or Recycling

If you can’t sell your car seat—or simply don’t want to—consider donating or recycling it.

Donate to Charities or Shelters

Many organizations accept gently used car seats for families in need. Local women’s shelters, churches, or nonprofits like Safe Kids Worldwide may take them. Call ahead to confirm their policies.

Note: Some organizations won’t accept expired or recalled seats, so check first.

Recycle Responsibly

If the seat is damaged or expired, recycling is the best option. Some manufacturers, like Britax, offer take-back programs. Local recycling centers may also accept car seats, though they often charge a fee.

Never throw a car seat in the regular trash—it’s not environmentally friendly and may be illegal in some areas.

Conclusion

Selling a used car seat is a smart, sustainable, and profitable choice—if done correctly. By choosing the right platform, preparing the seat thoroughly, and being transparent about its history, you can find a buyer who values safety and quality. Whether you go local with Facebook Marketplace or cast a wider net on eBay, the key is to prioritize honesty and safety above all.

Remember, a car seat is more than just a piece of gear—it’s a life-saving device. By selling yours responsibly, you’re not only helping your wallet but also contributing to a safer, more sustainable world for families everywhere. So clean it up, check it over, and list it with confidence. That unused seat could be exactly what another parent needs.
