+1 Mustang seats looks good and are very comfy, I found it heaps cheaper to get the model seat you want then search on ebay, seems be alot cheaper then mustang website and it comes boxed and packaged as if it came from the website.
I ride a nightster so might be a little different but I just got the Vintage Touring seat and it makes a world of a difference
I also got the Mustang Touring seat -studded. 13 inch not 16 and a matching pillion seat which my wife is much happier with. The pad on the 2010 WideGlide wa like sitting on the fender. Very happy with both and can remove the pillion for a better look with a quick release knob. Works and looks good. I bought mine from Cruisercustomizing.com Much cheaper than buying from Mustang I found.
