Seat Foam

Most of our cars don't get the kind of use they used to and are stored and taken care of better. You will be fine. Using the better methods and materials doesn't hurt on limited use but can be most benifical on a daily or race car where a heavier than average driver
is getting pushed into a seat frame. The photo I posted is a A-100 seat used in a super stock scenario. They were light weight and not particularly up to the task from the get go.
