I have the stock seat from an R that has been shipped to American Soft Seat for the gell pad insert and memory foam. I just got the seat back and it is still not comfortable for me because the original seat is to narrow. They did a great job on the seat and I have the receipt for all the work. The gell insert makes a huge diff. from the stock seat. I just spent $150 plus shipping to have this done. I would take $140 plus shipping for the seat. Again, I will include the receipt from AMSSS just to prove the work was done.
