Newton had the breathable idea right.  But, can you imagine washing your baby's mattress in the middle of the night because your mattress failed to repel water?  Where do you put the baby for the time the bed needs to sit in a bathtub?  What happens to your furniture below the mattress when liquid leaks through?  Why are you spending almost $300 on a mattress with one firmness, and no edge support for when they start standing?  This is not a mattress that grows with your child.

Nook's mattresses are all 4 inches thick (the minimum a baby mattress should be), they use latex in their premium model which is highly allergic.   Their mattresses are breathable but they use foam.  Since all foam off-gasses and emits VOC's, breathable is bad in this case.  You do not want those emissions being inhaled by a developing child.   The price (which is way too high) doesn't matter on this because it is just a bad decision.  

Naturepedic did a lot of things right and were innovative in this space by making an "organic" mattress.  However, they use a polyethylene (plastic) coating on their mattresses to make them waterproof.  They try to dress up the plastic by calling it 'food grade', but plastic is not breathable.  Air does not pass through their mattresses in anyway.  When you go grocery shopping, you can buy good ingredients, but if you can't get to those ingredients because of a non breathable, sealed plastic coating, what was the purpose of buying it at all?
