As if the fully washable wasn't enough, fully breathable is the best feature of this mattress! Our little one sleeps face down in the mattress, and I have a huge peace of mind knowing that they are still able to breathe comfortably.
Love this mattress! It is more expensive but I got it on sale on a holiday weekend. It gives me peace of mind now that my daughter sleeps on her stomach. I also like that it helps to not get her overheated while sleeping.
