fatigue failure

adrian_turtleThis is a couch, so talking about "fatigue mode failure" suggests it fell apart because I came home from the airport and flopped down on it, exclaiming how tired I was. That's not quite the mechanism. For those of you who know about the failure mode of my old bed, it might have been something like that...only somewhat less dramatic.
This is a couch I've had since the summer of 1992, so it might simply have reached the end of its useful life. I don't know. This End Up makes furniture that looks more or less like this
http://www.thisendup.com/catalog.htm/1/42.htm , only mine has blue cushions.
It seems like it should be pretty sturdy, but I haven't been at all gentle with it. It's a couch, not a lamp, and I don't like the idea that I should *need* to be gentle with it.
The couch cushions are still intact, and so are the long boards supporting the cushions. The problem is with the wooden cross-braces supporting those long boards. Either the wood of the brace is splintering, or the nails holding the front of the brace to the inner-front of the couch frame are pulling out (incidentally chewing up a strip of the couch frame.) It's probably fixable. The problem is that *I* am not capable of fixing it.
