Been out of town, driving the new rig. So, I'm sorry for the late posting.
I'm not being clear enough. Sorry, The thigh bolster isn't the lumbar. On the sport seat it extends outward under your thigh. I appreciate the photo, and I agree they look like a tight fit, but it will keep me from being able to extend the thigh bolster and that is one of the most comforatable features of the seat.
