It’s made from a soft and stain-resistant fabric designed to allow ventilated airflow when the heat isn’t on. While running you can choose from low, medium, and high settings, with temps reaching up to 120 degrees Fahrenheit and an automatic 45-minute timer.

We found it to fit well on a variety of car seats. We especially liked the design of the side wings and straps for giving it a more seamless look. It, unfortunately, doesn’t offer added lumbar support but in general, was comfortable to sit on.

Buy from Amazon

The HealthMate 12V Heated Seat Cushion is a compact and comfortable seat heater made by Wagan. It has a touchably soft velour top layer backed up by a comprehensive heating element.

It has a simple switch control that lets you choose between low and high power modes. One thing we noticed that was definitely a mark against it is the lack of an automatic shut-off. If your outlet is live and it’s turned on it will continue running indefinitely.

It does include an inline fuse, which is nice, but we’d still really like to see that automatic shut-off.

Overall the HealthMate by Wagan is an okay choice for a value-priced seat heater but doesn’t really stand out from the pack.

The KINGLETING Heated Seat Cushion takes a low profile approach to the seat heater model. It’s much more slimline than many comparable seat heaters and looks a lot sleeker on premium seat materials like leather.

It’s not just in physical form where the KINGLETING stands out from the crowd though. The actual tech under the hood is excellent. It offers fully customizable temperature settings from 86 to 140 degrees Fahrenheit.

You can also adjust the automatic shut-off to 30-, 60-, or 90-minutes. That allows you to get just the right temperature for your comfort level and keep it going for the perfect amount of time.

It doesn’t have the molded padding or lumbar support some other seat heaters offer, but the slimline approach allows you to use the natural support of the seat much more effectively.

The cushioning itself is relatively basic, with a squared pattern of cushions over the heating elements. They warm up really quickly, with noticeable warmth coming through in around a minute.

One thing to keep in mind is that there isn’t as much variance in the high and low settings as we’d like to see. It gets hot fast, but it also stays quite hot even on the low setting. If you’re looking for more of a comforting gentle warmth than a heated seat you may want to look elsewhere.

All in all the AUDEW 12V Heated Seat Cushion is an affordably priced if basic 12V seat heater. It doesn’t have a lot of standout features, but provides reliable service at a reasonable cost.

Buyer’s Guide to Buying the Best 12V Seat Heater

When it comes to picking out the best 12V seat heaters safety and comfort are the name of the game. Anything that has a heating element in it should always include comprehensive safety features.

Below you’ll find out what comfort enhancing features to look for and the safety essentials you shouldn’t go without.


Pricing on 12V seat heaters is very favorable for consumers. You can get value priced models for $10 to $20, and top of the line units for under $50.

Unless you’re looking for some really specific features or a high-end finish there’s no reason to spend more than that.


The most important factor when comparing seat heaters is how comfortable they are. This is something a good chunk of your body will be pressed against for hours on end in a confined space.

You want to make sure that it’s supportive, molds to your body where needed, and doesn’t have any annoying pressure points. The heat produced definitely helps to keep your body loose, but it’s no excuse not to spend a little extra for one that will keep you fully comfortable.

Some things specifically to look for include a secure strapping system, molded padding over the heating elements, and definitely lumbar support.

Automatic Shut-Off

One of the most important safety features for a 12V seat heater is an automatic shut-off. They work in much the same way as on an electric blanket and prevent you from accidentally leaving your seat heater on after exiting your car.

If your car or RV has outlets that stay live even after turning off the engine, or if you’re plugging your seat heater into a battery bank outlet, this is even more important. Seat heaters are quite safe, but it’s definitely not a good idea to leave them running unmonitored for hours on end.

Temperature Settings

The most basic 12V seat heaters have only two settings: On and off. We prefer ones that offer a range of temperature settings that allow you to find your own comfort level.

The best 12V car seat heaters will even allow you to individually target different areas of your body. You can turn on the legs without turning on the back elements and get the heat just where you need it.


The controller on your seat heater is a lot more important than you’d think. Older seat heaters often use physical knobs that you turn to select your preferred heat.

They work alright, but they aren’t nearly as precise or as easy to use as models with digital controls. These let you select an actual temperature you want your seat at and can maintain it precisely at that level.

Top-end models often include timers that allow you to set a specific temperature and length of heating you desire.

Cord Length

The length of your 12V seat heater’s cord determines where and how you can use it. If you’re in the driver’s or passenger’s seat you really only need a few feet.

If you’re sitting in the backseat, or you’re riding in the living space of your RV, a longer cord is much more important. Look for the longest cord you can find that works with the seat heater you like.

It’s always possible to fold up the excess, but you’ll need an extension cord if it isn’t long enough.

Indicator Light

An indicator light is another important safety feature for seat heaters. They allow you to tell at a glance if your heater is still on.

That makes it really easy to double-check that you actually turned it off rather than just relying on the automatic shut-off.

Lumbar Support

Anyone who’s ever taken a long road trip before knows the importance of lumbar support. There’s nothing quite as annoying as stepping out of the driver’s seat with an aching back from doing nothing.

12V seat heaters with lumbar support offer excellent support for your back and provide soothing heat to your muscles. It ensures that you’ll arrive at your destination feeling loose and comfortable.
