After reading the negative reviews on this product, I admit that I delayed buying it for several weeks worrying that my toddler would be tumbling into public toilets all over town. Having finally bought it, I realise I need not have worried. My toddler is still happy to use it weeks later and has not slipped into a single toilet!
When I first opened the box, I was very pleasantly surprised at how sturdy it felt in my hands. I think the picture above does not do it justice as it looks like a flimsy piece of plastic. There is no indication of the sturdy plastic hinges underneath which not only allow it to be folded but also make it strong and prevent it from buckling.
With regard to it holding the toddler securely, I have not had a single problem so far with it supporting my 3 year old son. As long as you take some care to position the product on the toilet before lifting the child into place I can see no real problem.
The seat comes with a handy little bag so it's hygenic when you're carrying it about in a handbag and both seat and bag are easy to clean.
