I was hesitant to buy this toilet seat because I thought the measurements were off a little. After thinking about it for a couple of days, I decided to take a chance. What a great decision! I'm so happy with this toilet seat. It was extremely easy to install. It closes very quietly. it fits my toilet perfectly, and it looks very stylish (unlike the older types of seat risers). A wonderful feature is that the entire seat is easily removable for cleaning. I love this toilet seat!
