Dust mites are widely believed to be the single greatest source of allergens. It is common for dust mites to live in mattresses. Although natural materials like wool and latex do not provide a favorable environment for mold, mildew, and dust mites, these materials will not make a mattress dust mite proof.
Any natural non-waterproof mattress would require an external dust mite barrier encasing to prevent dust mites from penetrating the mattress.
The Naturepedic No-Compromise™ Organic Baby Crib Mattress features a dust mite proof, non-toxic, waterproof surface that cannot be penetrated by dust-mites. There is no need to purchase any additional dust mite barriers for this mattress.
