Molded all the way. I just removed a cheap flat pad & got the $175 model you looked at and it is WAY better than that flat junk, I gave it a short thought on searching for a parting out car to source a original but that is difficult and kinda like shopping for a used diaper after all these years the pads just do not survive the test of time,,,If I remember I contacted mfr & they did not sell direct, So I made sure I used a vendor selling the best molded unit and confirmed that is what was being purchased then low & behold, they drop shipped it from the Mfr. I can dig out the info when I get home.
