Protection questions, answered.

Is every protector fully waterproof?

Check the specific model’s stated waterproof areas and care instructions. A fitted skirt does not automatically mean waterproof sides.

How do I choose the right mattress protectors?

Choose the mattress size, then check its full height, including any topper, against the protector’s fit details. A fitted protector covers the sleep surface; a zippered encasement surrounds the mattress. Check the listed protection for this model. Our team can help you check the fit at our contact page.

How do I care for a protector?

Follow the manufacturer’s care label; washing and drying instructions have not been provided here. For help with a specific model, contact our team at our contact page.

What are the return conditions?

The comfort exchange covers eligible mattresses, not pillows, bedding, toppers, protectors, foundations, or other accessories. Confirm the applicable return terms before purchase at 120-night guarantee.

What warranty comes with a protector?

Warranty terms vary by brand and model; each product page lists the term when the maker states one. Keep your receipt and product labels. Find help with a claim at warranty coverage.
