I also have a bad back.. It's a little on the hard side when you first sit on it, but not an uncomfortable hard. I did 150 milesthedayI putit on, and I was okay.

I personaly like the feel. I would describe it as firm not hard. I think part of the comfort for me personally, is the shape. It fits my rear better than other seats have. Hope this little bit of info helps

 

That was a bad description on my part, you're right. Firm is probably the best way to describe it.
I put about 400 miles on it yesterday. It seems to be breaking in and softening up. I also have back issues, and I had no problems there. Overall, im satisfied with the seat, no regrets on the purchase.
I'll get some pics up later after I clean the love bugs off from the ride yesterday.

Ya'll ride safe this weekend. The crazy cagers are everywhere, and they're all in a hurry.

 

Firm is the best description. I have about 10k on the seat and it is a real joy. We go 2up a wife likes it better than the stock.
