Seat Replacement

I was just wondering if its possible to put seats from another car (more comfortable) into my car... its an 03 cav coupe... if i could fit other seats in my car, which ones? and how difficult would it be to get em in there? Any ideas welcome!

only thing you go to worry about is if brakets for the seats line up with the bolts... or i know a site which takes Tenzo R racing seats and uses the stock cavy seat braket and mounts it to the seats.
