I have a Saddlemen seat (bought very slightly used from a member here). I like the looks better than stock. As you can see, it has an integrated pillion. The pillion was off my bike when I bought it. The seller gave me the pillion, but not the required bracket to mount it. So the Saddlemen eliminated that problem for me. I'm not sure it is any more comfortable than stock. I'm good up until about 2 hours. For a long trip recently I used an Airhawk cushion. That worked quite well for me up 6 hours. Not the most aesthetically pleasing, but I could remove and install it without removing the seat, so no big deal.
