[Gary in NJ]

I have a theory on the shape of the seats. I don't think that the seats have a general lack of lumbar support, but they are narrow at the shoulder which forces you to sit/lean forward, albeit somewhat supported.

I'm 6'1" and only 165 pounds, but I have an athletic build. I have a narrow waist but somewhat broad shoulders and back. While I can get my back into the lower part of the seat (lumbar), my upper back (through the shoulders) is not touching the seats. I'm hoping as my seats break-in, the area at the shoulders will become more compliant.
