Many of you may already know this, but those of you who do not may find the following information helpful in avoiding the tremendous burden that I just went through in returning a non-fitting toilet seat cover to the retailer. Apparently, there are both round and elongated toilet seats. It looks like the "elongated" version--the one that I needed--is something like two inches longer than the "round" one.
Although I would probably still classify myself as a novice in this area, I am by no means inexperienced in shopping for toilet seat covers. I have lost count--perhaps because I never thought to make one--of how many times I have bought this product before. This, however, was the first time I ended up with a misfit.
