I don't wanna be that guy suggesting the obvious, but is she aware there's a lumbar support bar? I assume so cause many find it to be crap, but there's also plenty that can't get by without it
You could swap in the plush leather seats from a Limited as they'd fit right in, but getting the wiring to work is a bit of a project if I'm not mistaken. Otherwise you could always look into getting the seats reupholstered by a local shop, they can do practically anything you want for the right price. Color isn't a problem so much as the print/design, and even then many people here that have gotten their interior reupholstered were even able to get fabric whose design very closely matched the OEM print, lots of times it almost looks factory. At that point you could even just get the passenger seat done and save some money, though I would personally do the driver as well just so it matches a little better
