Yes, I have one and love it.
I first bought a RoadSofa in 1996 for my 95 Ultra. Their factory is 30 mins from me so I rode there for measurement and fittmant. It had gel and heat. In 2001 I bought another RoadSofa for my ‘01 Ultra. In 2010 I bought my ‘06 CVO Ultra and kept that seat off the ‘01 for it. In 2011 I ran into the Saddleman rep at a bike event and asked him if he would refurbished the seat. He was so taken by my loyalty, and the fact that I was still riding on 10 year old seat, that they gave me a new one! It came with gel and heat. They wanted to keep the old one for display, and for examination of wear, usage and crushability.
In 2012 I bought a Corbin and put the RoadSofa in storage. The Corbin was nice, but not comfortable for me. I ended up using an AirHawk cushion on top of it. Finally, in 2016 I went back to the RoadSofa, sold the Corbin and never looked back.
My only complaint about the RoadSofa is the heat in summer. When parked in the summer sun the gel retains heat and can fry you. In winter the gel becomes like blue ice and holds the cold till the seat warms up. On my ‘01 I used a lamb skin pelt over it. On my ‘06 I have resolved the heat with a BeadRider.
I highly recommend the seat, my only suggestion is to get it without gel.
