The difference in price is mainly due to some materials, and to the way the pad is built. The foams in the 7490 are thicker than those used in the 7460. Also, the 7490 is built exactly the same as the 7990 leg pad (knee cradle, leg channel, etc are identical), whereas the 7460 is a simpler, easier to construct version of the 7800 and does not have the same features. Because the 7490 is a more complex build with better internal foams, it costs more.
