What makes a mattress protector truly waterproof?

A truly waterproof protector has a complete barrier layer (usually polyurethane) that prevents any liquid from passing through to your mattress. Look for products with 100% waterproof guarantees and test certifications.

Are waterproof protectors hot and noisy?

Modern waterproof protectors use advanced materials that are quiet and breathable. Look for cotton terry or bamboo surfaces with silent waterproof membranes. Avoid cheap vinyl protectors which can be noisy and hot.

Can I wash a waterproof mattress protector?

Yes, most quality waterproof protectors are machine washable. Use warm water (up to 60°C for some brands) and mild detergent. Avoid fabric softeners as they can reduce waterproofing effectiveness.

How long do waterproof protectors last?

Quality waterproof protectors typically last 3-5 years with proper care. Premium brands like Protect-A-Bed offer 10-year warranties, indicating superior durability and confidence in their waterproofing.
