Best Overall: Purple Portable Seat Cushion
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.
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 Lumbar: Dreamer Car Lumbar Support Cushion
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
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 Budget: Everlasting Comfort Wedge Car Cushion
The Everlasting Comfort Wedge Car Cushion is one of the most popular seat cushions for riding in the car, and it also is an affordable option. This car seat cushion is made of high-density memory foam to give support to your tailbone and seat and features a wedge design.
Many reviewers find that this wedge-style car cushion eliminates pressure points and makes it more comfortable to take long trips in the car. However, some people complained that the non-stick rubber back left stains on the leather upholstery of their car. If you have light-colored upholstery, you may want to consider protecting the car seat from the backing material of this car cushion.
