I bought some Tushies for my house and they were awful, they were so thick that they broke my toilet seats. I then bought new toilet seats and little stick-on bumpers, but they fell off.

I then visited a friend who had an older Tushy and it was thin enough that he had no problems.

It's like they switched to a cheaper version without testing it, and then marketed the hell out of it.

I ended up replacing all my Tushies with Amazon's toilet seat with a built in bidet. It's decent.
