The Best Waterproof Mattress Protectors, According to Testing

Our top-tested mattress protector, this five-sided style from Coop Home Goods easily stretches over your bed like a fitted sheet and is simple to pull off when spills occur. When we poured water on the upper panel, not even a drop seeped through to the inside, proving the protector to be truly waterproof. It's also impressively quiet and was given one of the highest ratings for producing little-to-no noise during our Textiles Lab evaluations.

It's machine washable and dryer safe, so it's easy to clean with the rest of your bedding. When we laundered the protector in the Lab, it looked good as new without noticeable wear, and there were only minimal signs of shrinkage. The side panels aren't as sturdy as some of the other protectors we tested, but it's stretchy enough to fit mattresses up to 18 inches deep.

WHAT USERS SAY: The upper material is made with a soft and smooth polyester and rayon blend that's comfortable and feels cool to the touch, according to testers and GH analysts. One analyst who has tested plenty of protectors said, "I immediately noticed how soft it was compared to other mattress protectors." Online reviewers said it's not even noticeable underneath their sheets and noted that it lies flush with their mattress without shifting.

Online reviewers with young kids and pets who are prone to having accidents at night shared that it has kept their mattress totally dry. One reviewer who had previously used a more expensive model that leaked said, "My son had an accident in my bed and NOTHING made it through! This one is great."

It's a five-sided protector with a cotton terry cloth upper and waterproof backing to keep water from seeping through into your mattress. The upper panel is comparable to a bath towel, so it soaks up and holds onto moisture. Some online reviewers said the machine washable protector takes quite a while to dry fully for this reason. Along with the featured mattress protector, SafeRest also offers a silky smooth viscose option and a version with thicker padding for a plusher feel.

WHAT USERS SAY: Boasting more than 279,000 reviews on Amazon (including over 217,000 five-star ratings) with an average 4.6 rating, this mattress protector has undoubtedly kept many beds safe from spills and leaks. The cotton material is soft and barely makes a sound, according to online reviewers who said it's not as crinkly as other affordable protectors they've tried.

One GH analyst uses this mattress protector on her kids' beds and shared, "It's very easy to get on [thanks to the] stretchy side panels and very quiet." She credits the protector for saving her kids' mattresses when they're sick. According to the brand and reviewers, it's also a great option for college dorms and first apartments.

The caveat: Some online reviewers said the protector runs warm, so it's not the most ideal option for hot sleepers.

If you're a sweaty sleeper, your first thought of a waterproof mattress protector may be "hot and stuffy." But that doesn't always have to be the case. SlumberCloud is one of our favorite brands for cooling bedding, and its Performance Mattress protector is made with moisture-wicking Tencel and uses Outlast technology that stores and releases body heat.

The brand only recommends laundering the protector two to four times per year to keep it in the best shape and prevent damage to the waterproof lamination, so it may not be ideal for someone who's more prone to accidents.

WHAT USERS SAY: This protector is loved by testers and GH analysts alike who said it really helps them maintain a comfortable, stable temperature as they sleep. Even testers who sleep on heat-trapping memory foam beds said this protector keeps them from overheating. One tester who has a cooling mattress and uses this protector shared that she was initially nervous the protector would take away from the cool feel of her mattress and be too warm but remarked, "I was pleasantly surprised that my mattress was just as cool and comfy as always when I laid down."

Our testers said the five-sided protector was easy to put on their bed. Some testers appreciated the thin layer of fill inside, which gives the protector a slightly padded feel, but other testers wished they couldn't feel the protector through their sheets. One also commented that it "felt almost slippery under the sheet and made it harder for my sheet to stay in place."

This simple five-sided cotton protector from Avocado is GOTS-certified, meaning the entire manufacturing process and materials used are certified organic. The protector sandwiches a waterproof film between two layers of soft and stretchy cotton jersey for a barely noticeable feel on your bed. And even the waterproof polyurethane is derived from cornstarch, so it's natural through and through.

When we poured water onto the protector in the Textiles Lab, the cotton did absorb some of the liquid, but none of it seeped through the protector, keeping the surface below totally dry. If you have a tall mattress, Avocado also offers a deep-pocket option.

WHAT USERS SAY: The protector recently won a Good Housekeeping 2025 Bedding Award, earning top scores with consumer testers and in the Lab. All our testers gave the protector near-perfect scores for staying quiet as they slept at night. "There's no noise involved with this mattress protector when you toss and turn at night — impressive for a waterproof protector," shared a tester.

A tester who spilled water on her bed shared that the protector stopped water from soaking into her mattress and said it dried quickly post-spill. Plus, testers who are self-proclaimed sweaty sleepers reported that it keeps their bed from soaking up and holding onto their sweat for a fresher feeling mattress. They also rated it highly for staying securely in place on their beds.

One tester did note that the protector was a little oversized for his mattress, explaining that it was loose in the corners, which caused the material to bunch up under his sheets. The brand recommends washing the protector at least once before putting it on your bed because it's designed to shrink slightly to better fit your bed, and it can be dried on low heat.

Some mattress protectors are equally as loud as they are uncomfortable under your sheets. But when we evaluated this pick from Airley in the Lab, it produced the least amount of volume, making it a great option for those who are particularly sensitive to sounds at night or who simply don't want to feel a crunchy protector under their sheets. Airley's mattress protector is made with a cover of smooth Tencel lyocell and has a waterproof lining to block spills. Plus, if you run warm at night, this protector is breathable and helps you maintain a comfortable temperature as you sleep.

Because the topper is designed to accommodate deeper mattresses, it may be a bit loose on shorter mattresses, which could cause shifting.

WHAT USERS SAY: Our testers unanimously rated this protector as being quiet and comfy. One tester described it as "unnoticeable" and another said they experienced "no plastic-y sounds when moving." A tester shared, "It kept me cool and dry, which I loved," and another noted that her old mattress protector left her bed feeling felt hot and humid, while "with the addition of the mattress protector, it felt cool and comfortable."

Another tester-favorite feature: Labels inside the mattress indicate which sides are long and short, eliminating the guesswork from making your bed.
