Question about the Z's seats for the bigger guys

STi 5

I went for my first test drive the other day in a 2010 Touring Sport. The whole time I felt the seat jabbing into my back. I'm not sure if it was the bolsters or what. I haven't had a chance to go back to the dealer and look more closely at the seats themselves. All I thought of while driving was how uncomfortable it was. Anywho, I was wondering do the more husky individuals who own a Z have the same issue or not. Is it a setting I could change, ie like a lumbar adjustment knob etc. Any insight would be most appreciated, as it kind of left a sour taste in my mouth toward the Z considering I have a pretty long commute. Thanks Guys.
