Have a look at Sargent
I have a Sargent that I like pretty well, although I returned the pillion saddle. It is contoured much differently than the OEM pillion saddle, and my wife didn't really have a complaint about the comfort of the OEM pillion saddle anyway.
I use a Givi topcase, with a pretty thick back pad, and between the combination of the Sargent's shape and the topcase setup, my wife couldn't get comfortable. So, when I sent the pillion saddle back, I got a skin from Sargent to recover the OEM pillion saddle to match the rider's saddle. It looks sharp and the comfort is fine for short to medium rides. For longer rides, my wife uses an Airhawk cushion, and I've got an Alaska Leather sheepskin buttpad.
