orthapaedic

Hi, I have a c36 with electric seats. How difficult would it be to replace these seats with the c43 seats that have the enhanced back support? Has anyone done this mod? Is it worth doing? I haven't sat in a c43, but my back has given me some grief of late and I am thinking what I may be...

Just seen an option that seemed to me to be pretty rare or at least a rare combination. A V reg C240 Classic (estate), cloth seats, but with the orthapaedic controls. Not sure if they were electric or manual adjust, but it was def. a oem orthapaedic controller on the drivers seat...
