Thank you everyone. I really appreciate your input. I ordered the one from Wayfair and think I will put it on the round table in front of the window. I didn't want to do that because my cat likes to sit there. I think that's where it would look best.
It will be about 5" wider than the table. Will that look okay? I did find pictures on Pinterest of trees on tables, and the trees were wider. I tried to cancel the one from Pottery Barn, but they said it's processing for delivery. I don't think I will like it since it's a Colorado Spruce and not a fir, so I think I'll be happier with the one from Wayfair. I just won't open it and will return it to the store.
