We just purchased our second Mayfair/Bemis toilet seat for our family bathroom. We have 2 children who currently use it, a girl and a boy. It's functional, attractive and is a nice solution. However, like other reviewers mentioned, there are quality issues and functionality limitations that could really use some work.
-Functional design, the nesting seat is a great solution
-Does the job (best for girls)
-Attractive, looks nice
-Not all that expensive
-Screws that come with seat are too loose. They loosen up over time and the whole seat starts to slide around on its hinges. This causes a misalignment of seat with bowl and (in our case) it can damage the rubber tabs. Ours actually shredded from sliding around and hitting the bowl at an angle.
-The screws rusted over time, and I had a very hard time removing them. Had to use a lubricant and tools to remove them to replace the seat. This time around I treated the screws before inserting them. I recommend getting stainless steel screws if you can.
-The seat is made of pressed wood (not REALLY wood), and when nicked it will suck up fluid (water, pee). Over time in our case the spot cracked and the "innards" started coming out. That's why we replaced it. Unfortunately I noticed the one I got also has a couple nicks I didn't notice.
-Not great for little boys who sit to pee. They will invariably pee between the seat and toilet... spilling on the front of the seat or on the floor.
-This seat is heavy, if you accidentally drop it, it will bang down hard and could accidentally hurt a little hand if the child tries to lower the seat on their own.
I was not aware of the KOHLER K-4732-0 Transitions Quiet-Close Toilet Seat, White seat when I purchased this seat again when the first one had to be thrown away. I probably would have paid the extra money for better design.
