hi, I wonder if anyone can provide me with any insight into what's happening to my toilet seat. The toilet is a plain standard one about one and a half years old. I put the wooden seat on after we moved in but a few days later the seat gradually started moving to one side. Tightening the bolts had no effect and eventually the parts started wearing away and we replaced it with another one. I thought perhaps it was the way I fitted it so this time I got himself to do it but the same thing is happening all over again. My brother thinks maybe the 'holes' for the seat are not in alignment. Anyone got any ideas?.
