New couch - Now or later?

I hate our couch. Ok, I'm grateful for its service, but... it's more than 10 years old. It's not very comfy. The color is outdated. And all kinds of fluids and food rests have been spilled and smeared over it since my daughter was born 2.5 years ago.

I had it professionally cleaned half a year ago and it was ok for a while, but now it looks horrible again. Only the cushions can be washed, the rest I try to protect with a blanket and whatnot, but my daughter manages to get it dirty anyways.
