I *think* I remember them being strapped to the chair. It did look similar to the one you posted. The main thing that I do remember is about the high chairs - they are really small. DS didn't fit so we had to get him a booster seat. With all of the wiggling, trying to stand up, standing up, ect that he did I am surprised that it didn't fall out. This is part of why I say that I believe they were strapped down.
