Cotton Terry Cloth Waterproof Mattress

We take product accuracy and customer satisfaction very seriously and we want to address the concerns you’ve raised.

First, there is no false advertising—the product description clearly states that the top layer is made of cotton terry cloth, while the backing is a waterproof polyurethane layer designed to protect your mattress. The material breakdown you referenced (80% cotton, 20% polyester) refers to the fabric composition of the top layer, which is standard for terry cloth to enhance durability and absorption. The waterproof backing is not fabric; it is a specialized protective layer, which is exactly as described.

Regarding waterproofing, this protector is waterproof as described as well. We would love to converse about your testing methods as many other customers do find that it is waterproof. Please feel free to contact us at support@ellajayne.com and we will ensure that you’re taken care of. Thank you!

Thank you for your feedback. We would like to clarify for future shoppers that a waterproof mattress protector cannot be made of 100% cotton alone, as cotton is naturally absorbent rather than a liquid barrier. A simple search into waterproof bedding will confirm that a waterproof membrane must be laminated to the fabric to serve its purpose.
The 100% cotton designation refers to the top terry surface that actually touches your body, providing a natural and breathable feel. The polyurethane backing and polyester skirt are necessary components to ensure the product remains waterproof and offers the stretch needed to fit various mattress depths.
When installed properly on a mattress within the intended depth range, the elastic is designed to hold the protector securely in place. We appreciate the opportunity to clarify these standard bedding constructions for those seeking an effective balance of natural comfort and reliable protection
