As the speed of cars continues to increase, the safety of car seats has become a key consideration for designers.
The headrest is one of them. In order to protect the driver's head safety, the ergonomic design is somewhat different. For example, some low-profile models have only two headrests in the back or no independent headrests.
For the whole seat, there are other things. Everyone who has seen it will know it clearly. Many seats are not only in design, but also in the details of materials. Some models will add some extra storage space to store items. This is very convenient for everyday driving.
