Love it so far!!
We were originally going to buy all sorts of extra things to protect our baby from off-gassing, including a mattress cover that would direct the gasses down beneath his crib. For some reason it usually costs SO MUCH to get a crib mattress that is free of all those nasties, so I had pretty much settled on buying a regular mattress and cover it. AND THEN, I saw this one! Price is perfect, the way it fits in our crib is perfect, the firmness is great (super important for little ones), it's not noisy when weight is shifted, there was NO smell when we took it out of the packaging, and now we don't have to buy the extra piece to protect our baby from chemicals in his mattress!
