Could someone take a look at this site:

and tell me what would cause the railing to break and what would cause
the chair to break?

All glue will fail eventually and all chairs will eventually need
repair. It doesn't help if you abuse the chair. I've repaired a few
chairs and glue joints can fail in as little as a few years or as long
as 50 years. It partly depends on the design of the chair and partly
on how it is (ab)used.
