After trying nearly EVERY travel potty seat on the market, I feared DD2 and I were trapped in the house. Finally I found the Potette Plus. It looks strange, but it sits VERY sturdily on any toilet and comes with a carrying bag. It also can be used as a stand alone potty about the size of the Baby Bjorn Little Potty. It's about $15 at BRU. The travel ones that fold into thirds and fourths I found pinched, but worse than that, they sagged tremendously under DD's weight. (She was only 22 pounds at the time!) She was never comfortable enough to actually go while using the fold up one. I read the reviews, but thought she would be light enough it wouldn't matter. I was wrong and should have listend....
