My Specialized Expedition came without a suspension seat. The bike is basically a comfort bike -- you ride pretty upright with your weight on your seat. I got a cheap aftermarket suspension seat (it's some kind of bungee cord suspension that can be adjusted by twisting to the desired tension.) That was a few years ago. The bike gets a lot of abuse (I use it as my winter beater) and the suspension still operates like it did the day I got it. I wouldn't want that kind of seat on my touring bike, but it adds significant comfort to the ride on the Expedition. I don't recall the brand or where on the internet I got it. Sorry.
