Not sure if I’m the right one to ask, perhaps someone else on the newsgroup
could give you more details. I just removed the padding from my seat and
replaced it with a 20" tube. I tried for a while to lay it out in some sort of
pattern, but found that after manipulating it into the cover and then inflating,
that the tube had it’s own idea of how it was going to lay in there.

A Semcycle seat has a hole in the bottom of the seat frame which I stuck the
stem out of. Even that did not stay after a few miles. Someone told me to tape
down the back of the seat to keep it all together, but I haven’t the heart to
tape it up, thinking that it will cheapen the looks of my pride and joy.

I made an air seat out of my old-style Schwinn seat, which Semcycle uses, and I
haven’t had any trouble with the cover popping off. It bulges out some in the
middle, but otherwise doesn’t move. I don’t know what I did differently; perhaps
I put more of the tire in the front, or inflated it less.
