The thought of using school bus seats has occurred to me several times. I haven't had the opportunity to physically compare the two side by side but I think they would be a very close match. I think also they could be adapted for the 2nd seat position fairly easy as I think the width between the two is comparable. The bus seats may not be wide enough for the 3rd position. The height between the two may be radically different also. I am going to try to make a physical comparison as soon as I can find a school bus seat. Will take some pics and try to describe the differences.
