Peterbilt replacement seats?

I have a pair of ultra leather Talledega wide rides in my Pete...it's like riding a concrete block. They were like that when the truck was brand new and haven't gotten any better. Look real good but hands down the most uncomfortable seat I have ever sat in.

Now, to be honest...I had a new Pete in 2000 and installed Tallededa low wide rides in it and they were a much better seat then. Don't know what happened between then and now but these seats in the '07 are a pain in the $%^#.
