This is going to sound strange but that REALLY brings back memories. My Grandparents had a soft toilet seat and when we were little we thought that was just the ultimate .
My grandma also buys the soft ones!! My sister always hated them...because every once in awhile the vinyl would crack and she swore up and down that it pinched her butt everytime she sat on it!!
Oddly enough, she seemed to be the only one in the family with that issue!
I got a new one for the upstairs bathroom. It slowly closes. It will not accidently slam down. I was so impressed when I installed it, I had to watch it over & over as the lid and seat slowly went down. I know, I have to get a life!
