My experience with Triumph's Comfort Seat is more positive than for the others posters. My Trophy came with the heated low standard seat, which I found to be uncomfortable for any lengthy trips. Last year a friend offer me his Comfort Seat to try out since he initially didn't find much improvement either. I used it for a weekend trip to a rally in northern Georgia and put perhaps 1,800 miles on it by the time I returned home. I found the Comfort Seat to be so much better than the stock seat that I offered to buy my friend's seat. When he decided to keep it, I just ordered a new one (~$180) and have now put nearly 60K miles on it and still like it.
This past spring I bought a used Corbin seat and tried it for another weekend trip, but found that it didn't suit me as well as the Comfort Seat. I would like to try a Russell Day Long saddle, but the logistics of ordering it sight unseen and untested, as well as the price and the need to sacrifice a stock seat, have stopped me from getting one.
YMMV...
