That's one of the few complaints I have about mine. I do a lot of 10+ hour journeys, and my previous HHR's base model seats weren't at all good, so I bought some power seats out of a higher model, but even with the lumbar adjust at minimum, they were a lot more supportive. After 3 of these 1200 mile round trips in the 3, I'm thinking I need to add some support, it hasn't been terrible, I've found a reasonably comfortable position, though it's far more reclined than the optimum position I was used to in the much taller HHR.
