Is 31 weeks too early to set up baby swing in living room?

Have had her swing since I was about 20 weeks from my shower, sitting in the box. I’m about to be 31 weeks and tempted to put it together since I’m feeling a nesting burst today... or is it insanely too early? Was thinking of putting a throw blanket on it to keep dog/cat hair off and to just have them get used to it being out.
