I have used bei-beis and rohos since '67 I really
loved the bei-bei because it was comfortable and
pretty cheap a 35$. trouble is, it sprung leaks
pretty easily. they were made by vulcanizing 2 pieces
of rubber together face to face and then inflating. i
patched them lots with standard bicycle tire patches.
that worked great but about a year was all i could
ever get out of them. to find the leaks, you fill up
too hard with air and stick them under water. i use a
roho now that i found along the freeway about 15 years
ago. i leave it partally inflated as i need only
about 2 inches of cushion and it is a 4 inch. the low
pressure developed by only what my too wide butt puts
on it is about 16 x 18 ( 288 )divided by 225 pounds or
just under 1 lb per sq inch. never a pressuire
problem - well 1 or 2, and no leeks yet. lucky i
guess. a good rubber cement with a patch is what i'd
use if needed. autozone has some 3m weatherstripping
cement they lovingly call 'gorilla snot'. i use that
stuff everywhere. best of luck.
