Thanks! I just realised that they are called 'booster' seats. Still not up with the names of things.

I checked out eBay and there are lots of FP ones and a couple of Beetles. There is also another one 'On the Go' that folds up into a case. Will proably buy one off eBay as I am watching a few. Amy eats on a normal chair but we have to watch her closely and a booster seat is a better idea.

Thanks again for your responses, you have been a great help.
