This mattress has a 6" natural latex core encased in our water resistant EcoWool Puddle Pad Outer. We take a natural rubber core and cover it with our wool puddle pad fabric.
A Great option for those who live in a moist environment prone to mold growth or those trying to avoid any cotton due to asthma or allergies. (The wool outer can stretch, so is not advised if the previously mentioned situations are not your situation. A quilted outer will hold up better in the long run.....)
