My wife loves riding with me (and riding her own bike when able) but says that the passenger seat isn't wide enough (I measured it to roughly 10") and I've been wanting a backrest for myself so I started looking at some options. I think I have it narrowed down between a studded Mustang seat (w/o backrest, looks like it will be high enough with the passenger seat for my lower backs liking) and a Saddlemen Explorer Special. Just wanted any inputs on these two or any others that anyone could recommend. I'm leaning more towards the Saddlemen because it looks like the backrest for me would be higher but all of the reviews I've read said that it is quite firm (at first). Also I can't find any width dimensions anywhere, the Mustang seat is about 12" for the passenger which I think would suffice for her. Thoughts? Thanks in advance.
