Hi All,
Just wondering if anyone has tried to add foam to a Corbin seat.

I have both a Corbin Seat Set and an Ultimate Seat Set. I like the looks of the Corbin but like the comfort of the Ultimate. I was thinking of removing the cover on the Corbin and adding some high density memory foam and giving it a whirl.

Any thoughts would be very helpful.
