Best Car Seat Cushions: More Comfort on Long Rides

The most common material used to make seat cushions is memory foam. It can feel hard for petite people, but it’s great at conforming to the shape of your bottom for extra comfort. Memory foam cushions are recommended for people who normally sit for long hours since it’s effective at relieving strain exerted on the back. However, it’s known to heat up because that’s how it maintains the impression of your sitting position. 

A softer option for lighter people is shredded foam, which is made up of shredded pieces of memory foam. The cushion feels lumpy, and the pillow is moldable since the pieces of foam move around independently. It’s also less prone to overheating. However, you need to fluff the pillow to align the foam pieces.

Bamboo charcoal is eco-friendly, soft, breathable, and comfortable. The material helps with moisture absorption, so you don’t have to worry about leaving sweat marks on the seat. It’s also effective at neutralizing odors and has antibacterial features. For that reason, it’s more expensive than other options. 

The Xtreme Comforts Coccyx Seat Cushion with a U-shape cutout is ergonomically designed to provide pain relief and improve blood flow. The ultra-deluxe body active memory foam distributes your body weight across the seat and relieves pressure from your tailbone. It also remains uniform in density no matter how long or how often you use it.

It remains firm on the car seat due to its non-skid, anti-slip bottom. It also sports a unique rounded shape rather than a typical squarish design. This body-contouring design provides ample comfort for your hips and bottom. As for the cushion cover, it’s removable and designed with machine-washable mesh that promotes air circulation and breathability.

Despite being an ergonomically contoured seat cushion, you may find it a bit large. It measures 18 by 14 by 3 inches, which may be too big for smaller car seats. Also, since the cover has a zipper, it may leave scratch marks on plastic or leather car seats.

The Fortem Seat Cushion is designed with thick, heat-responsive memory foam, which is designed to contour to your body. This helps to maintain proper driving posture and relieves pressure from your coccyx. The cushion also has a U-shaped cutout to relieve pressure from your spine. The bottom is reinforced with non-slip rubber to prevent the cushion from sliding when you move around in your seat.

The Fortem cushion is a great travel companion since it's lightweight and has a carrying handle on the side. In addition, it has a removable and washable velour cover that feels soft to the touch. It's an orthopedic cushion recommended for anyone with sciatica, back pain, and a herniated disk. But you can still use it as a lift cushion if you’d like to make your seat higher.

Unfortunately, it may be too small for some car seats, and it may feel uncomfortable around the thighs. It can also be a bit stiff when new, and it takes some time before the memory foam starts to soften. Also, the velour cover doesn’t inspire confidence that it’s going to last long.

The U-Are Cool Seat Cushion and Lumbar Support Pillow uses both gel and memory foam for a better sitting experience. It has orthopedic properties and relieves pain-related issues, including sciatica, pregnancy back pain, hip discomfort, backaches, and spine issues. The cushion is made of 100-percent memory foam with a breathable mesh middle that gives you the sensation of sitting on clouds.

To keep your rear end more cool and comfortable, the cushion has a heat disbursing cooling gel that transfers heat to other parts of the cushion. The bottom is slip-resistant and fitted with straps that can be secured on the seat. You can carry it with you to yoga class or the office in the ergonomic zipper bag provided.

However, it’s not the most durable seat cushion. It flattens out faster than other cushions. Also, despite its cloud-like sitting experience, some find it too firm. Moreover, it comes with short straps that may snap or not fit snugly on larger car seats.

The Kingphenix Car Seat Cushion is slim, sleek, and looks just like it belongs inside your vehicle. Sitting just 1.2-inches tall and measuring 21.26 by 18.5 inches, this cushion is thin and lightweight, which makes it ideal for anyone who doesn’t want a thick or bulky product.

It’s made with polymer memory foam and silicone gel, which deliver exceptional comfort and reduce pressure on your coccyx. When you sit on this memory foam and gel car seat cushion, it evenly distributes your weight, takes pressure off painful areas of the body, and is comfortable.

The cushion is covered with breathable material that features full, smooth seams to mimic the look of your car’s seats. On the bottom, the cushion has non-slip material to prevent sliding, movement, or slipping. It’s an excellent companion for any driver or passenger.

The ComfySure Car Seat Wedge Pillow combines comfortable cushioning with a slight wedged angle for increased support. At its tallest point, the cushion stands three inches high and angles downward, so you get a little lift while sitting in your seat.

This seat cushion is made with high-density, therapeutic-grade memory foam, which offers maximum comfort by molding to your body’s shape. It won’t flatten out over time and can support up to 500 pounds.

The wedge angle of the cushion helps alleviate some of the physical stress of sitting and driving, helping to relieve pain in the coccyx and tailbone as well as potential pressure sores. The bottom of the car seat cushion is covered in a secure, gripping non-slip material, so you won’t slide around or be uncomfortable when you drive.

Xtreme Comforts Coccyx Orthopedic Memory Foam Seat Cushion is our top pick. It’s a high-quality car cushion that provides excellent back support and ensures comfort on the road.

For those who are on a limited budget, we recommend Fortem Seat Cushion, a versatile accessory that can be used in car seats and office chairs.

The foam density determines the maximum weight capacity that the cushion can handle before it flattens out permanently. Some manufacturers don’t indicate the weight capacity, but you can tell how much it can handle from how thick it is. For instance, a three-inch-thick heavy-duty foam is denser than a two-inch one. It can, therefore, take on a heavier weight. 

Depending on the manufacturer, some cushion covers are waterproof and others are water absorbent. A waterproof cover can be beneficial for short drives if you don’t want to ruin the foam with a spill from a drink. However, it can leave sweat marks on your clothes. For long drives, or if you get sweaty often, prioritize water-absorbent covers that you can air dry after a journey. 

Compare the size of your car seat to the cushion you want to buy. You don’t want something that’s hanging over the car seat since it will push at your knee pit and make you uncomfortable. Also, if you have a continuous driver and passenger seat, you can get a wider seat cushion to cover both as long as it fits.
