It will likely fit your car
I've had the cushion only for a week or so.  But so far, it fits the bill.  The most important thing you need to know about this cushion is that, unlike many on the market, it can go on your car's seat without making it tough to get in the car or have your head hitting the roof of the vehicle.  This is due I think to its softness and its limited thickness.  So I recommend the purple cushion despite its relatively high price.
