Waterproof vs Water-Resistant
Waterproof construction is designed as a barrier; water-resistant fabrics may only slow or repel moisture.
The short answer
Start by defining the job the protector must do. Then compare coverage, surface textile, waterproof membrane, mattress depth and laundering instructions.
What to compare
Top-only, fitted five-sided and zippered six-sided designs serve different needs.
Separate the sleeping-surface fabric from any fill and the waterproof membrane.
Check supported mattress depth and the exact washing and drying instructions.
How to make the decision
Avoid treating a single marketing word—such as organic, cooling, natural or waterproof—as the whole decision. Check the construction and evidence behind the claim.

Use the stronger claim only when you need it
Water-resistant fabric can slow or repel moisture, but it should not automatically be treated as a waterproof barrier. If the goal is protection from spills or nighttime accidents, verify that the product is actually described as waterproof and identify the barrier material.
