I am a driving instructor and drive 2014 Corolla LE ECO. I spend a lot of time in the passenger seat and find it very low and uncomfortable.The driver seat is a somewhat better since it is height adjustable. I used drive a Yaris before and the seat was vastly better. I have tried the cushions, Obus form and the likes but it still kills my back...So I am faced with a dilemma to either change the seat or get a different car all together. So I was wandering if anybody has experience changing the seat. Thanks for you reply,Mike
