The comfort is there, I was concerned
by the seat valve being under the
seat. I have had to let out air
pressure of seats like these before as
they can be tough to sit on for long
periods. Being able to get to the
valve to let out some air is very
important. So having the seat valve
under the seat was a concern. before
heading out I inflated the back rest pretty firm and the actual seat just a little softer. It was very comfortable for my first trip out. I also feel the that the width of the setting area of over 20 inches adds to the overall comfort. One other thing that adds to the comfort I feel is that the floor is at a slight tilt to the back of the boat. Nothing to big but just enough to tilt the front of the boat up so that you don't feel like you are going to slip out. Recently there has been a lot f talk about this with other tubes so they addressed this issue very well.
