The front and rear driving seats of a car can basically be modified, but there must be a certain degree of matching in the choice of chairs. The width of the first chair should be able to be placed in the original position of driving before and after, and the height and angle can be adjusted and changed. Whether the slideways of the second chair and the second chair match can of course be changed (generally, the slideways of the chairs are changed). Limitation of the range of movement of the third front and rear slideways. Changing these needs very professional technicians to operate, comfort is very necessary, but safety is the first. Do you have any questions for me to continue to help you?
