Before we got our new car, the seats in the old car started to give much less support than they used to. It started to bother my husband, who stands for the bulk of his work day (he's a butcher). I would say take your wife to Canadian Tire or even Walmart and check out the cushions and things. Buy what you think could work, go out to the parking lot, give it a try within reason while it's still in the package with the Aveo and return what doesn't work. It's hard to say way will work and what won't without trying. We ended up with a little lumbar cushion for about $10 and it was great until we bought a new car. I gave it to a friend and she's using it now.
