Had a similar problem- turned the headrests 180 degrees- all is better.

Just a quick update, just in case anyone is having the same problem. I got the Obus large ultra forme seat back. It's not perfect because it pushes you forward in the seat a bit and it will never equate to the comfort of a real nice car seat, but it definitely provides shoulder support that wasn't there before. I'd still like a set of SS seats, but failing that, this is a decent solution for anyone with an HHR and a long torso.

 

You can order the performance seat from the SS an replace your regular one with it, I did it in me SS on the passenger side.

Would say the SS butt rest is 2 inches deeper, and much more comfortable on longer drives.

 

I'm 6' 4" 300+ and was leery of my wife's '06 2LT, but she has power driver's seat, so, all the way back, and all the way down and I'm comfy. I have old RECARO KRX seats in my Opel Sportwagon and REALLY love them
