What to Look for in a Car Seat Cushion

Type

Identify the type of car seat cushion that meets your needs. Wedge-style cushions are triangular in shape and tilt the pelvis back to assist in maintaining proper posture. Lumbar cushions provide targeted support to the lower back. Full seat cushions provide extra comfort for your shoulders, lower back, and seat. Standard seat cushions with no automotive-specific features can be a great option if you're looking for a car seat cushion that can also be used to add comfort to your office chair.

Material

Cover material and cushion filling play a large role in determining how effective and durable a car seat cushion will be. You should look for a car seat cushion with a breathable cover for enhanced temperature regulation, especially if you plan to use the cushion for long drives or in hot weather.

Inside the car seat cushion will be a filler material to provide comfort and support. Foam is the most frequent choice for a car seat cushion but it's likely to compress over time. If you want to keep a springy seat for many miles, you may be better off looking for a high-density memory foam car seat cushion. Foam cushions sometimes hold heat. If this is concern for you, shop for a car seat cushion with a breathable cover and gel foam to assist in dissipating heat.

Features

The benefits of a car seat cushion can extend beyond support and comfort. Other features such as a massaging, cooling, or heated car seat cushion can enhance your drive. If you're interested in these options, keep in mind that you'll also need a power source to plug your car seat cushion into. If you don't mind a cord extending from your seat cushion to a power supply, then you can enjoy a warmer, cooler, or more relaxing drive.

FAQ
  • What is the best foam for car seat cushions?

    A high-density foam will prevent the cushion from collapsing under pressure. And since memory foam offers excellent pressure-relief qualities, it's frequently the top pick as a foam for car seat cushions. However, it may retain heat so look for a memory foam cushion with gel to prevent trapped heat.

  • How do you clean car seat cushions?

    Regularly remove your car seat cushion. Shake it outside of your vehicle to dislodge any loose debris. Set aside. Clean the car seat where the cushion typically rests. Then, vacuum the car seat cushion itself. For cushions with removable and washable covers, periodically wash and dry the cushion cover according to the manufacturer's instructions.

  • How do you install car seat cushions?

    This depends on the specific design of the cushion you choose. Installing most car seat cushions is as simple as placing the cushion on the seat of your vehicle. Many simple car seat cushions have a pebbled, grippy underside to prevent the cushion from sliding during use. Lumbar or full car seat cushions will often have one or more straps that wrap around the car seat to secure the cushion and prevent it from shifting out of place.
