After repeatedly addressing the (classic) seat sag issue myself, I see that JMS method goes after the concave driver's seat profile. After feeling like I was sitting in a bathtub I cut out a 13" wide strip of dense 1/4" foam and made two 3 folds at 15" intervals and installed it under the seat foam. I know the new seat foam and 1/4" foam will again compress, but it's any easy fix. Sitten' "proud" now!!!!
