There are many reasons you might be on the market for a good waterproof mattress protector. Maybe you like to drink your coffee (or glass of wine?) in bed and are prone to accidents. Or maybe you have a toddler still working through the bedwetting phase of potty training.

Whatever the reason, there are a million products on the market and it can be tough to sift through which make the most sense to buy.

That’s why we did the research for you to pick the best waterproof mattress protectors. Read on to learn more.

  • Size and care. Look out for mattress protectors that are machine washable and dryer-friendly.
  • Materials. A lot of waterproof mattress protectors are made from either vinyl or polyurethane. If you’re looking to stay away from vinyl (and its possible toxic fumes), opt for a protector that has a vinyl-free coating.
  • Price. Waterproof mattress protectors can range from $20 to $100. Depending on your needs, you can find a protector that fits within your budget.

  • Customer reviews. Of course, any product on the market that calls itself waterproof will claim that it’s fully waterproof. So it’s important to check out what reviewers say to get the real story. We also made sure reviewers rated our picks positively on comfort and durability.
  • Materials. The materials in mattress protectors can make or break your night’s sleep. Some — like vinyl — don’t have any breathability and make a crinkly noise when you’re in bed. We avoided fabrics that are known to be uncomfortable and interfere with sleep.
  • Elements beyond being waterproof. Sometimes, you need more than protection from liquid — like protection from allergens or bedbugs — so we included picks that took that into consideration.

Pricing for mattress protectors depends on what size mattress you’re buying for. We looked at full-size mattress prices.

Best cooling waterproof mattress protector

Red Nomad Waterproof Mattress Protector

  • Price: $$

The fabric in this protector from Red Nomad is made from bamboo, which is really effective at regulating temperature while also being naturally hypoallergenic, antifungal, and antibacterial.

Reviewers say this is truly a lifesaver for those who sleep hot but still want protection from liquids. Some reviewers recommend that, if you’re finding yourself washing this one a lot because of bedwetting accidents or frequent spills, consider purchasing a new one within a year to make sure it can still effectively protect your mattress.

Best waterproof mattress protector for allergies

SureGuard Mattress Encasement

  • Price: $$$

This cotton terry mattress encasement is an awesome option for people with allergies. Mattress encasements fully protect all sides of your mattress, which makes them ideal for protecting against allergens.

Additionally, woven fabrics have been suggested as the best option for protecting against allergens. Cotton terry is a great woven fabric option for waterproof mattress protectors. Not only is it hypoallergenic and breathable, but it can also absorb a lot of water.

The brand recommends also buying the regular mattress protector for frequent accidents, since it’s much easier to clean and take on and off your bed. It might seem a little overkill to buy multiple protectors, but it can be worth it if you’re trying to safeguard against allergens and frequent accidents.

Best waterproof mattress protector for bedbugs

Utopia Bedding Zippered Mattress Encasement

Price: $$

The United States Environmental Protection Agency (EPA) suggests using protective covers that fully encase your mattress as a precaution to help prevent a bedbug infestation in your home.

This encasement from Utopia fully zips around your mattress to encase it entirely, making it a really good option for people worried about bedbugs.

Reviewers love the protection they’re able to get from bedbugs, but don’t recommend using this if you’re dealing with frequent bedwetting, since it’s a little hard to clean. But it works well for waterproof protection for less frequent spills or accidents.

Best waterproof mattress protector for bedwetting

SafeRest Premium Hypoallergenic Waterproof Mattress Protector

  • Price: $$

With over 100,000 reviews on Amazon, this popular pick is definitely a top-rated, bestselling choice. It’s made from cotton terry, which is woven fabric that’s soft and can absorb a lot of liquid.

It also has a membrane layer that’s vinyl-free, which helps make it more breathable and protective against liquid.

If you’re planning on taking advantage of this for its hypoallergenic properties, the brand recommends washing it quarterly to get rid of any dust or dust mites. If you plan on washing it more than that, try keeping this out of the dryer and buying two, so you can let them air dry.

There are a bunch of elements that can go into how you choose the right waterproof mattress protector:

  • Type. There are multiple kinds of mattress protectors: top protectors, (which only protect the top of your mattress), 5-side protectors (which protect the top and 4 sides of your mattress), and encasements (which zip up and protect the entire mattress). Top protectors are most common, but some reviewers don’t like the lack of side protection. Encasements usually aren’t necessary unless you’re trying to protect against bedbugs or allergens.
  • Materials. There are many kinds of materials you might come across while shopping for a mattress protector. A 2007 study suggested that woven materials (like cotton, rayon, and polyester) protect against allergens while still allowing for breathability. Other materials, like bamboo, have been shown to regulate temperature. Vinyl can be a great guard against bedbugs, but it can be uncomfortable to sleep on.
  • Durability. Durability is a really important factor when choosing your product — especially if you’re expecting to wash your mattress protector a lot because of bedwetting or incontinence. You can tell how durable a protector is by checking customer reviews to see how well it holds up. But keep in mind that if you’re using this as a just-in-case protector, durability might not be a dealbreaker.
  • Warranty. Many protectors will have some kind of warranty to guard against any potential defects. This is important to make sure your protector doesn’t rip or fail because of problems with the manufacturing.

Whether you tend to spill drinks a lot, have young children still working through wetting the bed, have pets prone to accidents or wet paws, or have someone in your home experiencing incontinence, a waterproof mattress protector can really help extend the life of your mattress.

Not only do mattress protectors help you with keeping your mattress clean and free of stains, but they can also help ensure your mattress warranty doesn’t become void.

Some companies won’t replace mattresses with defects if there are any noticeable liquid stains — even if the defect has nothing to do with those stains.

Additionally, certain waterproof mattress protectors can also help protect against allergens and bedbugs. This can help make you or your loved ones much more comfortable while sleeping, and potentially prevent a bedbug infestation in your home.

Always take a look at the care instructions on any waterproof mattress protector. Some can be washed and dried with your regular bedding, but some might have special instructions that can help increase the longevity of your protector.

Also, if you’re planning on washing and drying this a lot — like more than once a week — consider buying multiple protectors at a time and avoid putting them in the dryer.

Dryer heat has been shown to weaken some fabrics and make them less likely to protect from liquid.

How does a waterproof mattress protector help?

Waterproof mattress protectors offer protection for your mattress from accidental spills, bedwetting accidents, and night sweats. And they ensure a longer lifespan. They are easy to clean, which helps prevent the development of mold and bacteria growth within your mattress.

Mattress protectors can also protect you from any preexisting allergens, bacteria, bed bugs, or pests living in your mattress.

What are waterproof protectors good for?

Waterproof mattress protectors are a great investment for nearly everyone. They work to prevent your mattress from coming into contact with nightly perspiration, which wears down the materials inside the mattress over time.

They also offer protection from spills, bed bugs, dust mites, and bedwetting.

Are mattress protectors uncomfortable?

Most mattress protectors are very thin and barely noticeable. For optimal comfort, choose one made from breathable materials, like cotton, rayon, or polyester.

What’s the difference between a mattress topper and a mattress protector?

A mattress topper helps change the feel of and comfort of your bed, whereas a mattress protector extends the lifespan of your mattress by fighting off stains, allergens, sweat, and more.

These two items should be used in conjunction for the best results.

Mattresses aren’t cheap, and a good waterproof mattress protector can give you some peace of mind that yours is protected.

There are a lot of different mattress protectors on the market that make similar claims, so always check customer reviews to find out how waterproof, durable, and comfortable any given product actually is.
