This is a seat height adjustment cushion for full bucket seats. It was used with a BRIDE full bucket seat. It raises the seat surface by about 3-4cm. For those who want to drive with a slightly higher viewpoint in a full bucket seat, it can be used by placing it between the original cushions. Since it is made of a soft material, it can also improve the cushioning if the original cushion is hard. I bought it new and used it for about a month, but I am selling it because I decided to replace the seat itself.
