#15523, "RE: Trout Unlimited tube question" In response to In response to 2
I put it in the seat bottom under the foam. It keeps the foam from seperating and helps keep you a little bit higher. If the back rest is uncomfortable, go buy a stadium seat style piece of foam and stick it behind you. It took me several trips to work out all the bugs in that tube. Make sure your straps that go around the pontoons are tight enough.
