We have a change table with a bath underneath it, and I agree that it's difficult to use in terms of getting the baby out and then flipping the top back! We didn't use the bath for very long anyway as Jacob just grew and grew so rapidly that he was too big for it anyway and went into the big bath.

The change table part has straps on it so that he can't fall off it, but I also noticed that it says only to use them until babies are 12 months old.
