The covers for the Original and Essential Crib Mattress are not waterproof, however, they are water resistant! Most messes will stay on the machine-washable cover to make cleaning up messes easy. For waterproof protection in later months, you can add our breathable and waterproof Crib Mattress Pad.
Our Waterproof Crib Mattress brings everything together in a 2-stage design combining our dual layer breathe-thru cover on the infant side and an additional layer of waterproofing beneath the breathe-thru construction on the other side for bigger messes in toddler years.
