What types of car seat cushions are available?
Car seat cushions serve different purposes. Choosing the right type is the first step toward a more comfortable drive.
Ergonomic back and lumbar supports
These models are designed to support your back. They target the lumbar spine and encourage an upright sitting position. Firm models, often made of plastic or shape-retaining foam, provide lasting support. Adjustable versions can be fitted to the natural curve of your spine.

Protective covers and seat cushions
These products protect your original seat upholstery from wear, sunlight and dirt. Options range from simple decorative cushions to full covers that wrap around the entire seat. The SPEEDWAY complete set is one example of comprehensive seat protection.
