The 7 Best Car Seat Cushions of 2020

Best Overall: Purple Portable Seat Cushion

Buy on Amazon Buy on Bed Bath & Beyond

Sink into some serious comfort with the Purple Portable, a popular option for a car seat cushion. Made from a unique polymer grid that is only 1-inch tall, the Purple Portable adds seating support without adding too much height—a common problem with plush car seat cushions. 

The open grid structure allows air to circulate freely, helping to keep things cool while you’re traveling in your car. The benefit of the hyperplastic polymer structure is support for your back without too much resistance for your hips, and a cushion that won’t become compressed after extended use. 

People that have tried the Purple seat cushion for the car rave about its comfort and durability when compared to memory foam car seat cushions. It also doesn’t slip and slide as much as some other car seat cushions, make it a good option for staying put. Some reviewers report toting this cushion from car to office chair every day so that they’re never without Purple’s unique comfort. However, some people felt that the cushion was undersized for heavier weight individuals, so it might be best to go with one of Purple’s larger, thicker cushions in that scenario. 

Best Overall, Runner-Up: ComfiLife Non-Slip Orthopedic Gel & Memory Foam Seat Cushion

Buy on Amazon

Memory foam seat cushions are common for use in the car, and this gel-infused option from Comfi-Life is a good choice if you don’t mind sitting up a little higher in your vehicle. The Comfi-Life Gel Memory Foam Seat Cushion is constructed of memory foam, with a top layer of gel to assist in keeping the cushion cool and comfortable. 

This car seat cushion is 2.8 inches in height and includes a removable, washable cover. Since it’s made of high-density memory foam, keep in mind that the firmness of the cushion can be affected by temperature fluctuations. Especially in cold weather, many users mention removing the cushion from the car; otherwise, it can become firm and hard and won’t return to its soft, supportive state until the material warms up again. 

Plenty of people rave about the protection this provides for the coccyx and how much this cushion helps them to ride in the car for extended periods of time. However, a common complaint is that this car seat cushion flattens over time, reducing its effectiveness.

Best Lumbar: Dreamer Car Lumbar Support Cushion

Buy on Amazon

For a car seat cushion that cradles your lower back and loves your lumbar, consider the Dreamer Car Lumbar Support Cushion. This ergonomically designed lumbar car seat cushion is adjustable and is designed to support your spine and promote proper alignment even while driving. 

The Dreamer Car Lumbar Support Cushion is made of memory foam and features a softcover. Unfortunately, the cover isn’t removable, so plan to vacuum and spot clean this car seat cushion. Most people find the lumbar support to be excellent—once they get the position right. Some reviewers initially were disappointed in the fit and feel of the cushion but found it was improved by using the two adjustable straps to raise or lower the height of the cushion.

Best Full Seat Cushion: CONFORMAX Gel Car Cushion Combo Set

Buy on Amazon

Add some comfort and support to the entire seat of your car with a full cushion set, like the Conformax Gel Car Cushion Combo Set. This set includes a seat cushion and lumbar cushion that can be individually positioned, unlike a one-piece car seat cover. This design gives you the most support on your daily commute or long drive. 

Each of the gel cushions is covered in Conformax’s Airmax breathable comforts, designed to enhance the breathability of the foam cushions inside. While some people still find the cushions hold heat, complaints are generally limited to occasions where they’ve been left in the hot sun for too long. Overall, users find this full car seat cushion set to provide excellent seat and back comfort. The set also proves to be durable, with some users reporting several years of use with little noticeable compression of the cushion. 

Occasional complaints usually revolve around the back cushion. Some people say that lumbar support could be improved, and others wish that the cushion was several inches taller for a better vehicle fit. 

Best Cooling: ZONETECH Cooling Car Seat Cushion

Buy on Amazon

Keep things breezy with a cooling car seat cushion, like this version from Zone Tech. This universal size car seat cushion is equipped with an intake fan that channels air through the breathable mesh material and keeps your seat and back comfortably cool. You’ll need to plug it into a 12V outlet for operation. 

This cooling car seat relies on the intake fan to push air out from the cushion itself, so the ambient air temperature in your vehicle will impact how effective this cushion is at keeping you cool. However, users find that the Zone Tech beats stuffy conventional car seat upholstery, and plenty of people report that this small fix kept them from trading in their car for one with air-conditioned seats. While the results aren’t going to be the same, it’s enough to keep you from sweating through your shirt on a hot drive to or from the office or a meeting.

Best Heated: COMFIER Heated Car Seat Cushion

Buy on Amazon

Make your drive even more enjoyable with a heated car seat cushion. Whether you live in a cold-weather climate or appreciate the relaxation offered by gentle heat, the Comfier Heated Car Seat Cushion is a great choice.

This heated car seat cushion stands out for its durable construction, fast heating, and auto-off feature. You can set the cushion to run for 15, 30, or 60 minutes before it will automatically turn off. Maybe one of the most common compliments of the Comfier Heated Car Seat Cushion is the fact that it doesn’t slide around on most car or truck seats, thanks to the included sturdy straps. Many reviewers that had to forego heated seats in their vehicle found this model from Comfier to be a suitable replacement and wouldn’t hesitate to recommend it as a heated car seat cushion.
