Yes, you can almost always rent a car seat from a major rental car company. However, it's a service you must reserve in advance and comes with an additional daily fee, typically ranging from $10 to $15 per day. While convenient for travel, there are significant considerations regarding cost, availability, and hygiene that often make bringing your own seat a better option for families.
The primary advantage is the sheer convenience, especially for air travel, as it eliminates the need to lug a heavy car seat through airports. Major companies like Hertz, Enterprise, and Avis offer this service. The critical step is to reserve the car seat when you book your vehicle. Simply requesting one at the counter is risky, as they are subject to availability and you could be left without one.
The downsides are substantial. The daily fee can add a significant amount to your total rental cost over a week-long trip. More importantly, you have little control over the seat's history. It may show signs of wear and tear, have hidden damage from previous accidents, or not be the latest model with the newest safety features. There's also no guarantee the seat will be the correct type (infant, convertible, or booster) for your child's exact age, weight, and height.
| Rental Company | Estimated Daily Cost | Reservation Required? | Seat Type Selection |
|---|---|---|---|
| Hertz | $13.99 | Yes, during booking | Subject to availability |
| Enterprise | $11.99 - $13.99 | Yes, highly recommended | Not guaranteed |
| Avis | $12.99 - $14.99 | Yes, at time of reservation | Varies by location |
| Budget | $11.99 - $13.99 | Yes, mandatory for guarantee | Limited options |
| National | $13.50 | Yes, via customer service | Typically convertible seats |
For many families, a more reliable and cost-effective solution is to bring your own car seat. You can check it for free with most when traveling with a child. This ensures you have a seat you're familiar with, that is correctly installed, and that you know meets all current safety standards.

As a parent who travels frequently with my toddler, I always bring our own car seat. The rental ones are a gamble. They're often grimy, can be outdated, and the cost adds up quickly—it's like paying for the seat twice over on a long trip. The peace of mind knowing our seat hasn't been in an accident and fits my kid perfectly is worth the minor hassle of carrying it through the airport.

From a purely financial standpoint, renting a car seat is rarely the best choice. At around $15 a day, a week-long rental can cost over $100. You can often purchase a new, certified booster seat for that price. If you're traveling by air, all major U.S. allow you to check a car seat for free, making bringing your own the most economical option by far. Reserve a rental seat only as an absolute last resort.

If you do decide to rent, your first step is to inspect the seat thoroughly before you leave the rental lot. Check the expiration date molded into the plastic—car seats expire. Look for any visible cracks, frayed straps, or missing parts. Make sure you understand how to install it correctly. If anything seems off, don't hesitate to ask for a different one. Your child's safety is more important than a few minutes of inconvenience.

We rented a car seat on a trip to Florida last year, and it was a mixed experience. While it saved us from carrying an extra item on the plane, the seat itself was clearly well-used and the buckle was a bit sticky. It worked, but it wasn't ideal. Next time, we'll probably just gate-check our own. It's one of those things you don't think much about until you're trying to install a unfamiliar seat in a hot parking lot.
