Frequently asked questions

What certifications should I look for in a waterproof mattress cover?

Look for OEKO-TEX Standard 100 certification, which ensures the cover is free from harmful substances. CertiPUR-US is common for foam, but for covers, OEKO-TEX is key. Also, check for hypoallergenic claims if you have allergies.

Can a waterproof mattress cover help with dust mites?

Yes, a tightly woven or encasement-style waterproof cover can block dust mites from entering your mattress. For full protection, choose a cover that encases the entire mattress with a zipper.

How often should I wash a waterproof mattress cover?

It's recommended to wash your waterproof mattress cover every 1-2 months, or more often if there are spills or accidents. Always follow the care instructions to maintain waterproofing.

Are waterproof mattress covers noisy?

Modern covers are designed to be quiet. Look for covers with a fabric top (cotton, bamboo, or microfiber) and a waterproof membrane underneath, as they produce less noise than vinyl or plastic covers.

Will a waterproof mattress cover make me sweat?

Quality covers with breathable materials like bamboo or cotton terry minimize heat retention. Some covers also have moisture-wicking properties. Avoid cheap vinyl covers, which can trap heat.

The SafeRest Premium Hypoallergenic Waterproof Mattress Protector is our overall winner due to its certified safety, comfort, and durability.
