Alteration of CF seats? Not comfy during long trips. Just read some threads and looking for some advice. I'm 5'7" and find that the small of my back is not supported. I also find that the space where my butt hits and the area where the seat back and seat base meet may not be filled with body mass. In other words, lack of support from CF seats. Maybe my skinny *** is a detriment. I have a base coupe, cloth seats. Read a post that the leather seats are more comfortable. I can pursue used leather seats from ebay and upgrade to power adjust and maybe some extra comfort or look to find a cushion for the seat. I have tried a lower back support with questionable results. I also tried a seat fusion but it slides around and I don't like the feel of it. I also read about a gel seat for a motorcycle that CF owner suggested. Any advice? My *** and small of my back is killing me. Please don't suggest to eat more, don't think that will solve the problem, (but it might) Thanks to all!
