Lightweight and breathable

Enjoy all the benefits of a waterproof protector, but without the heat retention. Our Amerisleep Waterproof Mattress Protector is super thin and vapor-permeable but still reliable and durable to keep you sleeping confidently and comfortably.

Ideal for allergies

Without a mattress protector, your bed accumulates dead skin cells, dust, and other germs. While dirt buildup isn’t healthy for anybody, it’s especially bad for sleepers with allergies. Our protector effectively keeps out dust mites and other allergens.

Shields against stains

Our waterproof protector can hold up to one liter of liquid and is machine-washable, so you can keep your mattress covered and your protector like-new. Plus, our protector never shrinks, so you can wash it as many times as you like without causing damage.

Frequently asked questions

Is the Amerisleep Waterproof Protector an encasement?

Our Amerisleep Waterproof Mattress Protector is not an encasement, so it doesn’t entirely shield against bed bugs, but it does fit like a fitted sheet so it’s more convenient to remove from your mattress and clean. Our fitted-sheet style protector wraps snugly around your bed to keep liquid spills, dust mites, and other germs from penetrating your mattress and causing damage.

How long does the Amerisleep Waterproof Mattress protector last?

Most people replace their mattress protector every 1 to 2 years, so we back ours with a 5-year warranty to ensure you’re covered from any manufacturing defects through the duration of your protector’s expected lifespan.

How much water does the Amerisleep Protector shield against?

Our waterproof mattress protector can effectively shield your bed against one liter of water. You’ll want to address larger spills immediately to reduce the chances of them breaking through the protector’s waterproof barrier and soaking your mattress.

Can you wash the Amerisleep Waterproof Protector?

Yes! If you happen to spill something colored on your bed and want to prevent staining your protector, you can easily remove it from your mattress and throw it in the wash. Many mattress protectors aren’t machine washable, making regular maintenance a hassle. Even when your protector isn’t at risk of being stained, you should still freshen it up periodically by tossing it in the washer and hanging it out to dry.

Please note, our mattress protector should not be machine dried, as doing so can cause the waterproof lining to pill and lose its effectiveness.

Does the Amerisleep Waterproof Protector come with a return policy?

Since our waterproof mattress protector can work with any bed, and not just our Amerisleep mattresses, they do not qualify for the 100-night sleep trial. All Amerisleep Mattress Protectors are final sale items and cannot be exchanged or returned.

Is the Amerisleep Waterproof Protector safe for kids?

Some vinyl mattress protectors have a chemical-like scent, causing many parents to question their safety. However, you can rest easy knowing our Waterproof Protector is OEKO-TEX® Standard 100 Certified, meaning it is completely free of any potentially harmful chemicals.

No nonsense shipping

The Amerisleep Waterproof Mattress Protector comes with free shipping within the continental US. We ship our mattress protectors direct to your doorstep via FedEx. And in most cases, they arrive in .

Please note: All our products ship separately, so if you’ve ordered a mattress, foundation, base, sheets, or any other sleep accessories to go with your Waterproof Mattress Protector, they may arrive sooner or later than your mattress protector. But don’t worry, shipping is always free.
