Mine seemed very hard out of the box. I previously had a stock seat with Spencer's seat mod which is softer (which I probably will sell if anyone is interested).
One year and some 3,000 miles later, the Sargent is softer than when new and is more comfortable. My only complaint with the stock and the Sargent is that I get the "roll forward" which is a hassle. That is why I got the Sargent in the first place and I still get it to some degree.
Other than that, the seat is great and the storage tube underneath is excellent for holding the registration and other items.
