Title: Not Firm
Review: This mattress is not firm. I see no advantage to it over the 3" version. Also, when I received my Alpha Mini Rocking Crib, the instructions said not to use a mattress over 5" and this one is 6" - great....We haven't used it yet, but it doesn't even compare to my first child's full size crib mattress - wish they had that quality for the mini crib.
