Will the TOTO soft close seat fit American Standard?

Hello All, Can someone tell me if the TOTO soft close seat, Round Front, AND Elongated, fit a wall hung American Standard oblong and round front. My parents were visiting from Hawaii this month and really liked the soft closing of the the TOTO units, so I want to get them some for Christmas! They have both an elongated toilet and a round front...Thanks in advance. I am asking because, I don't want to get them here in San Francisco, send them to Hawaii and have them not fit. My local TOTO dealer says there is a 90 % chance they will fit correctly. My parents are over 80 and the installation has to be really straight forward. Thanks in advance, Don

Toilet seats are generic in the US, so a round one will fit pretty much any round toilet, and an elongated one the other style. The exact overhang and curve may differ slightly, but it will fit. Same with color, the match will be close but may not be perfect.
