Natural Mattress Protector Guide

“Natural mattress protector” can mean anything from cotton or wool fibers to a product that still includes synthetic waterproofing.

Define your threshold first

Do you want natural fibers on the sleep surface, a high percentage of natural materials, certified organic textiles, or absolutely no synthetic membrane? Those are different requirements.

Waterproofing is the fork in the road

True liquid barriers commonly rely on a membrane. If a product is all-fiber, ask whether it is actually waterproof or merely absorbent.
