If you don't want to try the FG cloth and diluted PVA for glue ... (and I recommend it because it works well with foam) ... you would also be able to get a similar stiffening effect with criss-cross wrappings of ripstop packing tape around the white foam.
EDIT: Just looked at the avatar pics in the thread so far. Tubedude and myself seem to be more upright (upper body) and you may be leaning back a little, thus causing the tube to tilt back a bit.
Just based on tiny photos I know ... but it supports the idea that having a straighter seat back might be key to the problem.
This obviously would affect tall people more due to a higher centre of gravity.
So it is possible that little guys may be able to "slouch" and lean back more, and bigger folks may need to choose between a straighter seat, or a bigger wider tube design.
