I don't know!! I can't figure out why there are so expensive new anyway? What a rip off. I got mine with the tray on special for $77 woot. I also bought a highchair that sits on a normal dining chair, for $50. By the looks of it, that will work better than a bumbo, because you can't safely tie the bumbo to the dining chair. I hope you find something nice and cheap . FWIW there are two second hand baby stores in Strathpine that you can check out.
yes one on the main strip i will get hubbie to check it out next time he is out there. thank you sweet
