Sorry for the bump... Can anyone confirm if the standard seat cushion really can be swapped with the fold-flat version? It's been mentioned previously that it is possible but I get the feeling nobody's done it yet. I'm a little wary too, because I imagine there are at least some hinges and clips or something that aren't on my version.
I got roped into a sedan and the non-fold-flat back seat hasn't been an issue 'till last night when I almost got burned at Home Depot (was still able to cram 12' of rolled rug!). I've come to terms with the 4-door but I think fold-flat would add a lot of versatility.
