Moonlight Slumber Possible Safety Concern

[Krisrich]

I've read a lot of positive reviews on this mattress but I am left with one concern. Is the mattress very firm? Experts recommend buying the firmest crib mattress possible to reduce the risk of SIDS. Most reviewers comment on how soft the Moonlight Slumber mattress is. I understand that this might be comfortable for the baby, but is it the safest option? Thanks for your opinions and help!!

We have the Starlight Support Supreme Crib Mattress All Foam w/Visco, and it is very firm. The infant side is very firm and then can be flipped to a softer side when baby is older. The mattress is clearly labeled so there's no confusion.
