The Bemis Assurance 3" Raised Toilet Seat is designed to fit most standard round and elongated toilets, but it's not guaranteed to fit every toilet shape or size, especially those with unique designs or non-standard dimensions.

So, it's a good idea to measure your toilet and check compatibility first to be sure it fits well with yours.

Our research shows that the seat is quite stable and secure, thanks to features like the Clean Shield Guard and Snap 2 Secure system. These are particularly helpful if you have mobility issues, as they keep the seat firmly in place when you use it.

On the downside, it doesn't have a soft-close lid. Some people find this annoying because the lid can slam shut, which can be a hassle, especially for seniors.

If you really need a soft-close lid, you might want to consider other brands like Kohler or Toto, or look into aftermarket options to add this feature yourself, though that might take some extra effort and cost.

Overall, the Bemis Assurance 3" Raised Toilet Seat is great for standard toilets and provides a sturdy, elevated seating solution, but just double-check the fit for your toilet and keep in mind it doesn't have a soft-close lid.
