Organic crib mattress recommendations?

I’ve been looking at the Moonlight or Colgate mattress because they are both under $200. I can’t decide between the two. Some reviews say that Colgate is a harder/uncomfortable mattress but I know that’s important for preventing sids. Anyone have any experience with either?
