Rather than an ugly cover, consider adding more support inside the cover on the seat back. If not something within your ability, find an auto upholstery shop.
Bob:We've had a '97 Avalon for years. It's been great to drive.
I just got a 2002 Avalon XLS. Since driving it my back is killing me. It's like I get no lower back support and the lumbar doesn't catch in the right place.
If I take a towel, fold it until it's about 1/4" thick, then make an 'L' to where I'm sitting on part, and the other is on my back about 1/3 up, it takes care of the problem.
I'm 6' tall and way overweight (250 lbs).
Anyone have any suggestions on seat settings? If I have to I'll figure out a seat cover but I'd rather get the seat set.
Could there be a problem with the seat? Or just a problem with its owner?
