My sister had a great family seat for her three children, unfortunately after 10 yrs of use it was ready for the bin.
I have been looking and until now not been able to find one.
What is it?????
It is an adult seat with a built in child sea that flips up out of the way when you need to use the toilet. No need to remove the child seat and then forget to replace it.
I was lucky enough to find one on ebay, brand new. This particular one is called a Universal Toilet Trainer.
I have also found a website that sells another brand of these seats (thanks to another post for potty trainer reward charts). It is an American company and i do not know if they would post overseas, but it may be worth a try.
Here is the link:

Hope this helps someone.
