5-Year Warranty

Please note: Our waterproof mattress protector is designed to be machine washed and air-dried. Drying on high heat may cause the waterproof barrier to blister and peel, which voids your warranty.

Mattress Protector Benefits

  • 100% waterproof
  • Compatible with all mattress types
  • Fits mattresses 8 to 18 inches thick
  • Fitted-sheet style with elastic edging to keep the protector secure
  • Soft-to-the-touch cotton-blend jersey top

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.

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.

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.

Frequently asked questions

Does the Amerisleep Waterproof Mattress Protector trap heat?

Nope! Our mattress protector is vapor-porous, so it prevents liquid from penetrating the mattress but allows air to flow as normal. The Amerisleep Waterproof Mattress Protector is exceptionally breathable, shielding your mattress without causing sleep disruptions.

How thick is the Amerisleep Waterproof Mattress Protector?

The Amerisleep Waterproof Mattress Protector is paper-thin so it doesn’t feel bulky or bunch up below your bed sheets. Its lightweight design also promotes better airflow to ensure hot air isn’t trapped in the bed close to your body.

Does Amerisleep’s Waterproof Mattress Protector encase your entire mattress?

Nope. Our mattress protector fits like a fitted sheet and features elastic edging to keep the protector securely in place. We design our protector like a sheet so that it’s easier to take on and off the bed, allowing for more convenient cleaning.

Does the Amerisleep Waterproof Mattress Protector have a plastic scent?

It does not! Although many waterproof mattress protectors can feel like plastic or have an unpleasant chemical-like scent, ours is designed to feel soft and smooth and smell odorless. Plus, it’s OEKO-TEX® certified, meaning it's free from the harmful chemicals that can cause off-gassing and, as a result, it’s less likely to smell.

Does the Amerisleep Waterproof Mattress Protector qualify for the 100-night sleep trial?

Our Amerisleep Waterproof Mattress Protector does not qualify for the 100-night sleep trial. The 100-night sleep trial was designed to give customers a chance to test the comfort of a product and ensure it’s right for them, and since mattress protectors don’t play a role in your comfort, they do not qualify for the sleep trial.

Do waterproof mattress protectors make you hot?

Some waterproof mattress protectors can make you hot because they contain vinyl, and vinyl is a non-breathable material. Before buying a mattress protector, check to make sure it’s vinyl-free. While vinyl protectors are usually the most inexpensive options, we don’t recommend them because they can cause night sweats and as a result, impede sleep.

How long do mattress protectors last?

Most mattress protectors last around 5 to 7 years. Some can last up to 10 years while others only last 2 or 3 years. When shopping for a mattress protector, check to see if it comes with a warranty.

The length of the warranty is usually a good indicator of the quality of the product. Products with 2-year warranties may only last 2 or 3 years, whereas products with 5-year warranties are expected to last longer.

Should I use a mattress protector on memory foam?

Yes! If you own a memory foam mattress, we highly suggest buying a mattress protector to shield the foam layers from liquid spills. Memory foam is essentially one giant sponge, so when liquid seeps through bedding and the mattress cover, the memory foam layers directly below are ready to soak it up. Waterproof mattress protectors can prevent an accident from ruining your foam bed.

Do you put a fitted sheet over a mattress protector?

Even if your mattress protector is designed to work like a fitted sheet, you still need to place a fitted sheet over the top of it for better comfort. If you don’t place a fitted sheet on top of your mattress protector, you’ll end up sleeping directly on top of the protector. While that isn’t necessarily bad, most people enjoy the extra softness sheets provide.

What is the difference between a mattress pad and a mattress protector?

Mattress pads and protectors are sometimes used interchangeably, but they do have their differences. Mattress protectors are designed solely to shield your bed from dirt, germs, and spills. Mattress pads, on the other hand, are meant to add a little comfort to your mattress, as they contain cushioning materials in their tops.

Mattress pads usually fit like fitted sheets and offer some level of protection for your mattress, but they’re not true mattress protectors. Although a mattress pad may be a neat sleep accessory, it usually cannot shield your mattress from liquid, either, so mattress pads are not suited for protecting your bed from accidents.
