Thank you for all of this good information Ophelia. I have read elsewhere on this forum about that very seat...maybe it was your info that I read. I'll go back and re-read it if I can find it. If I don't succeed in modding my own seat or am inclined to trying the Asian style seat, I'll private message you for your friend's info.
So, to recap what I remember...the front portion has a higher hump under it and thus raising the foam portion higher. The rear hump does not push you as far forward because the top of the foam hits it farther back, allowing one to sit farther back. Also the front seat has more of a bucket to it, preventing one from sliding forward? I didn't study for this test...how did I do?
Do you remember what the price of said seat was at full price?
Thanks in advance for your kind reply,
