The Rockler struff you posted the link to is rubberised and usually
known as "Pirelli" webbing. This is useful for simple lazy work on
uncomfortable armchairs, but it's no use on an upright chair. Again
you're asking too much strain of it and it will go loose fairly quickly.

Actually I used this Rockler webbing to repair a rocking chair that had the
zig zag springs that kept breaking. The webbing has held up fine for a
couple of years now on a chairs that sees a lot of miles of rocking. The
webbing has not gone loose at all. If you have seen some that has gone
loose perhaps it was not stretched correctly when installed.
