I bought this as a replacement for an identical seat (same model number). The seat is pretty, comfortable, and easy to clean;. However, it has a new kind of fastener that is designed so that the seat is supposed to be easy to remove. They tout it as being easy to clean because you can simply pop the seat off to clean it. I have two problems with this. First, after the seat is installed, for me anyway, it is extremely difficult to remove. Second, it is difficult to tighten it adequately (because, on my toilet, the wingnut does not have room to turn and has to be forced) and consequently, the seat gets loose after a short time, but I cannot access the screws to tighten it. I know I didn't explain that well, but the bottom line is, the seat would be great if I could get it to be tight and stay tight, but as is, I am looking to replace it soon.
