The best degreaser, hands down, period, end of story, is simple green. I'm restoring a Fiat and I used the stuff to clean exterior surfaces. I'm amazed at the crud that it takes off.
If you're able, I'd recommend taking the seats out of the car and letting them warm up prior to a good scrub. Another option is to leave them there and put a blow drier or two in the car and let them run a few hours, to warm the car up.
On a W114 I once had, I recolored the seats. Prior to though, I took acetone (nail polish remover) and removed all kinds of crap with it. If you go that route, be careful or you might remove dye too...
