Ha ha. I highjacked it first. :-laf:-laf:-laf (Sorry Firefighter).
Jim: Yes, the foam isn't thick enough and the lower frame cuts off the circulation in your thigh. Some here on the TDR have taken the seat apart and add foam and have significantly helped the problem.
Firefighter: I know that someone on here has installed air ride seats in their Ram and are very happy. They are expensive, but they like them. Before I purchased my Ram, I used a Volvo VNL semi to tow my trailer. I put new air ride seats in it (top of the line National seats, leather, all adjustments, etc). They were comfortable, and I liked them, but my wife didn't. She hated all the motion associated with them, and would lock out the fore-aft motion, and would air down the seat so that there was practically no up-down motion. I felt that I had wasted $900 on her seat, and should have bought the $200 "buddy" seat. On a semi, which has very stiff springs, and very little spring travel, I think the air ride is a must, but on our Rams, which have a much softer suspension (comparatively), I don't think they are necessary unless you have a very bad back, arthritis, or some other health condition that makes even the ride of a 3/4 or 1-ton pickup too much to take.
