Manufacturers spend significant time and effort in testing and developing OEM seats, covers, and airbags. Hence, a factory-fitted seat cover is the safest and ideal solution.
If you still insist on adding seat covers to your new Maruti Suzuki car, ensure that they don't interfere with side airbag deployment, whether you buy them from your Maruti dealer or you add aftermarket seat covers. Check for a tear seam design / weak-seam stitching which allows the side airbag to rupture the cover appropriately. A universal seat cover design might not be the ideal solution. Therefore, it is better to go for a custom-fit or Maruti Suzuki Fronx-specific cover.
