Do a search and you'll find several threads on Sundowner seats. I've got one and love it. Tried Mustangs, but, for the money, you just can't beat a Sundowner. If you've got the Classic, it matches your bags as well. Get the backrest as well, well worth the money.
Lot's of favorable reviews on this board re the Sundowner.
I have one on my '05 FLHTCI.
Just finished a tour to Baja....Cabo San Lucas and back.
The Sundowner allowed many long days in the saddle with maximum comfort.
It works because of a better shape and firmer foam that resists deformation.
I have a sundowner seat and backrest and enjoy it. It is a lot more comfortable than stock. It did seem to move me forward some and being 6' 1 makes my legs a little cramped up some. Need to get me some highway pegs.

I had a sundowner on my RK and liked it so much I took it off before I traded it in. Well it fit on the new FLHX fine but did'nt match to well,So I sold it and bought the one for the Streetglide and it looks and feels great!
