I'm 6'1" 240 and I don't seem to have a problem with the seats. It feels comfy to me. But that could just be me.

 

It is really the only complaint I have with the CM. The seats suck, yes i have the stock seats and they have no support at all. I had to buy an old man lumbar cushion. I refuse to take car on long road trips b/c of the driver seat. To install lumbar supports is exspensive on stock seats. New seats will be over $800 and that is no fun on a new car.

 

Could the leatherette material on our CM be getting softer to the touch as time passes? Sure feels like it to me....
