Great feedback. Allow me to add more detail:
-Thigh Cushion seems too short (same issue I had in the 944), causing my legs to ache ( I find my leg muscles are tense a good deal of the time in this car, something I've never experienced in any other car)
-Seatback has insufficient lumbar support
-Seatback seems a bit narrow
-Seatback lacks shoulder support (I'm no football player, but I have wide enough shoulders that they stick out beyond a typical modern-day Coach airline seat)
Best seats I've ever had: OEM Recaros in my Mk2 Jetta GLI:
The OEM seats in both our '12 GTI and '12 Golf TDI (same seat, different fabric) are also fantastic--more supportive than the Porsche seat while being all-day comfortable.
