Mine's by Infantino. I accidentally bought one of the non-floppy ones the first time, but quickly learned that the kind that doubles as a playmat doesn't work because the sides of the cart are still exposed -- Ella's mouth found those nasty sides right away!
Check Babies R Us, too. If you want the one with toys, I can get it at BJs for you. At only $20 each, they are a real deal!
