The new automotive seat cushion is designed based on the optimization definition of seating comfort composition materials, to solve the challenge effectively of the balancing soft comfort and stable support, as well as the static comfort and dynamic comfort. A comprehensive evaluation of the seat cushion's static and dynamic seating comfort is carried out by means of a combination of objective testing and subjective ratings. The results indicates that the optimized design offers a wider and more soft support for the hips, flanks, and thighs accompanied by a pressure distribution aligning with the physiological characteristics of seated posture. In subjective evaluation,, all scores of optimized design are higher compared to the conventional design, Among them, the indicators of bottoming sensation and vertical vibration absorption increased from 6 and 7 points to 7.25 and 8 points, respectively, demonstrating significant improvement. The optimized design could balance soft comfort experience and stable support performance, achieving a synergistic improvement in both static and dynamic comfort. This design approach provides a reference for the optimization design and evaluation on seating comfort of automobile seats.
