Some people replace things on a regular basis which other folk seem to keep forever. Houses, cars, spouses, jobs. In our case it's toilet seats. For some reason ours don’t last long.
The latest failure was an oak seat from B&Q which split after little more than a year. Here it is reduced to kindling for the log burner. Actually I enjoyed making some more kindling, but it’s an expensive way to buy it.
Our replacement is a plastic seat made in Germany which I hope will last forever. However, after I’d fitted it I noticed the plastic is supposed to be environmentally friendly, whatever that means. It doesn’t sound good for longevity though. Environmentally friendly often means crap or doesn't work or doesn't last.
