Look at Corbin. Great looking and very comfortable.

 

Another vote for the sundowner. Have had it on all of my bikes ( sporty, dyna, vrod, and now the king) and fits me like a glove

 

Send it to mean city cycles for a memory foam upgrade. Less than $200 for both front and back and you can get it shaped how you want. My gf loves it.

 

Lots of alternatives out there. Want to spend $$$, go HD. Then there is the aftermarket (Mustang, Corbin, etc). Next is to have the stock seat modded by someone who knows like Butt Buffer who has done all my bike seats from sport bikes to cruisers. Great customer service, price and they are at most bike shows.
Lastly, strap on seat pads like Air Hawk or even sheepskin.
Hope you find what you are looking for.

 

+1 on the sundowner seat it took me a little to get use to it but the wife loved it as soon as she sat on it and after around a 400 mile ride if felt like sitting on a couch.

 

Keep an eye on the classifieds here on the forum. Lots of seats come up there and cheaper than buying new. I went with Harley's Hammock seat and both my wife & myself can ride ride all day with no butt burn. The BEST of any mod I've done.

 

I had a Mustang on my 07...for 60000 miles... just switched to a Sundowner...WOW... way better...Wife liked the Mustang...

 

I've started keeping my eyes open for a pillow top Ultra Classic seat for my King. I'm looking in classifieds here and on ebay. I've heard too many mixed reviews on the aftermarket seats to take a chance on buying one. Maybe I'm just a fun hating chicken ***! Being a cheap bastard doesn't help either.

 

Right now I have seats from Russell, Corbin & Mustang in my stable - all good seats - Mustang on the Ultra, it's is working for me - lot's of good choices out there - tom

 

My stock SB seat had me squirming after about half an hour. Replaced it with a Sundowner Solo and now I can ride all day.
