Newer vehicles may have seat side airbags which this seat protector will not block like fully elastic seat covers. However, the covers are held in place by a headrest hood, elastic back strap and front elastic drawstrings. Also, the waterproof seat back material doesn't slip on my Toyota Sienna's cloth seat covers. I bought one for the driver's seat and it worked so well for 6 months that I bought another for the passenger seat. Gorla guarantees satisfaction and that's a lot easier when your product is as good as these seat covers.
