You're standing at the Emerald Aisle, the sun is beating down on the tarmac, and you've got a toddler screaming because they’ve been in a metal tube for six hours. You’ve booked your "Midsize or larger" and you’re ready to go. But then you realize you forgot the one thing that actually makes the car legal to drive: the car seat. Renting a national car rental car seat feels like it should be a seamless part of the "Executive" experience National prides itself on, but honestly? It can be a total headache if you don't know the specific quirks of their system.
People think they can just show up and grab one. That's a mistake.
I’ve spent years navigating rental lots, and here’s the cold truth: car seats are an afterthought for most rental companies. While National is generally ranked higher for customer service than, say, some of the budget brands, their car seat game still relies on local branch availability and the cleanliness of a plastic shell that may have seen a hundred juice box explosions. You aren't just paying for the plastic; you're paying for the convenience of not dragging a 25-pound Clek Foonf through O’Hare. But that convenience comes with a literal price tag and a few logistical hurdles that might make you reconsider your packing list.
Why National Car Rental Car Seat Options Are Tricky
Most travelers assume that because National is part of the Enterprise Holdings family (which includes Enterprise and Alamo), the car seat inventory is massive. It is. But "massive" doesn't always mean "available right now." When you reserve a national car rental car seat, you’re typically looking at three categories: infant seats (the "bucket" style with a handle), toddler/convertible seats, and backless boosters.
Don't expect a specific brand. You won't know if you’re getting a Graco, a Cosco, or an Evenflo until you’re at the counter.
The pricing is the first thing that catches people off guard. Usually, it’s around $10 to $15 per day, though it’s capped at a certain amount for long-term rentals—often around $70 or $90 depending on the location. If you’re renting for two weeks, you’re basically buying a brand-new seat at Target prices, but you don't get to keep it. This is where the "convenience tax" really hits your wallet.
The Cleanliness Factor
Let's talk about the "ick" factor. It's real. National claims to clean their seats according to manufacturer guidelines, which usually means mild soap and water. They don't want to degrade the webbing of the straps with harsh chemicals. However, anyone who has ever used a rental seat knows that "clean" is a subjective term. You might find some crumbs in the crevices. If you’re a germaphobe, this part of the experience is going to stress you out.
I’ve seen seats wrapped in plastic that looked pristine. I’ve also seen seats that looked like they’d been stored in a damp shed. It's a gamble.
The Liability Loophole You Need to Know
Here is the most important thing to remember: the rental agent cannot install the seat for you. They won't do it.

Even if they like you. Even if you're an Emerald Club Executive Elite member.
It’s a massive liability issue. If the agent installs the seat and there’s an accident, the company is on the hook. You are responsible for the installation. This means if you aren't familiar with the LATCH system or how to thread a seatbelt through a rear-facing convertible seat, you’re going to be sweating in that parking garage for twenty minutes while your kids lose their minds.
Pro tip: Download the manual for common rental seats like the Cosco Scenera NEXT before you land. It’s the most common rental seat because it’s lightweight and cheap. Knowing how it works beforehand saves you the frustration of trying to find the "path" while your phone battery is at 4%.
Is the Emerald Club Any Different?
National's big selling point is the Emerald Aisle. You skip the counter, pick any car, and go. But what happens to your national car rental car seat?
If you’ve reserved a seat, you usually still have to stop by the booth or the counter to pick it up. You can't just find a car with a seat already in it—that would be a weirdly specific stroke of luck, and probably a safety hazard. This slightly defeats the purpose of the "skip the counter" perk. You’re still waiting. You’re still talking to a human.
What Happens if They Run Out?
It happens more often than National would like to admit, especially during peak holiday seasons like Spring Break in Orlando or Christmas in Denver. You have a "confirmed" reservation, but the branch ran out of boosters.
What then?
Legally, they can’t let you drive off with a child who requires a seat. Usually, the manager will try to "steal" a seat from the Enterprise or Alamo inventory next door. If they can’t do that, you might be stuck waiting for a return or, in some cases, they might tell you to go buy one at a nearby big-box store and reimburse you. It’s a mess. Honestly, if you’re traveling to a high-volume family destination, call the local branch 24 hours ahead. Don't call the 1-800 number. Call the actual desk at the airport.

The Alternative Nobody Considers
Have you ever looked at the "checked bag" rules for airlines? Almost every major carrier—United, Delta, American, Southwest—lets you check a car seat for free. It doesn't count toward your baggage allowance.
So, why pay National $100 for a ten-day rental when you can bring your own?
- You know your seat is clean.
- You know it hasn't been in an accident.
- You know exactly how to install it in thirty seconds.
- It's free.
The downside is lugging it through the airport. But if you get a car seat backpack or a "trolley" strap that attaches it to your rolling suitcase, it's manageable.
Safety Concerns and Expiration Dates
Rental car seats lead a hard life. They get tossed into bins, piled on top of each other, and baked in hot cars for weeks on end. While National is supposed to pull seats from rotation once they hit their expiration date or if they've been in an accident, the system isn't perfect.
When you get your national car rental car seat, check the sticker on the side or back. It will list the date of manufacture. If it’s more than six years old, ask for a different one.
Also, look at the straps. If they are frayed or twisted beyond repair, that’s a safety compromise. Don't be "polite" about this. It’s your kid's life. If the seat looks like junk, demand a replacement. The staff might huff and puff, but they have more in the back.
The Booster Situation
If your kid is older, the backless booster is the easiest way to go. It’s just a plastic base. These are the hardest to "mess up" in terms of installation, but they are also the most overpriced rental items. Paying $15 a day for a piece of plastic that costs $18 at Walmart is painful.
Some parents actually find it cheaper to Uber to a Target, buy a booster, and then leave it behind or bring it home. It's wild that the math works out that way, but it does.

Navigating International Rentals
If you’re using National in Europe or South America, the rules change. Car seat laws are different. In some countries, the ISOFIX system is the standard (similar to LATCH but often with more rigid connectors).
In the UK, for example, the laws around who needs a seat are based on both age and height (up to 12 years old or 135cm). If you don't book your national car rental car seat in advance for an international trip, you might find yourself in a legal bind. European branches are often smaller and have much tighter inventory than US "mega-hubs."
Strategic Advice for Your Next Trip
Stop thinking of the car seat as a minor add-on. It’s a primary piece of travel equipment.
If you are absolutely set on renting from National rather than bringing your own, make sure your Emerald Club profile is updated. There’s a section for preferences, but don't rely on it. A reservation is just a piece of paper; the reality is the inventory on the lot when you land.
- Inspect the harness: Pull the straps all the way out. Check for mold or deep-seated grime.
- Check the LATCH connectors: Ensure the "teeth" of the connectors aren't bent.
- Verify the age: Look for that manufacture date.
- Ask for the manual: If it’s not attached to the seat (they usually aren't), ask the agent to print a quick guide or find it on your phone immediately.
National is a premium brand. You pay a premium for the convenience of the Emerald Aisle. But when it comes to child safety, the "convenience" is often a bit of an illusion. You still have to do the heavy lifting—mentally and physically—to ensure the seat is safe.
If you’re worried about the cost, check your credit card benefits. Some high-end travel cards or insurance policies might reimburse rental fees for "essential travel equipment," though this is rare. Better yet, if you have AAA, they often have a partnership with Hertz (not National, unfortunately) that gives you one free car seat. It might be worth price-shopping if the $100+ car seat fee is a dealbreaker.
Basically, be your own advocate. The person at the rental counter is trying to get through their shift; they aren't a certified passenger safety technician. You are the only one responsible for that seat once you pull out of the lot.
Next Steps for Your Rental
- Check your itinerary: If you’re staying in one spot, buying a cheap seat at your destination might be cheaper than a 7-day rental.
- Call the local branch: Verify they actually have the specific type of seat (infant vs. booster) you reserved, especially during holidays.
- Pack a box of disinfecting wipes: No matter how clean the seat looks, you're going to want to wipe down the plastic and the buckle.
- Confirm your airline's policy: If you decide to bring your own, double-check that they provide a gate-check tag or a protective bag for free.
