Best Waterproof Mattress Protectors (2025), Shield Your Investment Against Spills

The best waterproof mattress protector should provide a perfect fit for your mattress, protecting it from spills and messes. However, we also believe that the best waterproof mattress protector should seamlessly integrate with the rest of your bedding, so your fitted sheets don’t slip and slide. The Saatva Waterproof Mattress Protector delivers on every front, earning a 4.5 out of 5 or higher in the materials, experience, and care categories.

Our in-house product tester was immediately impressed by how well it fit on the queen-sized mattress in our Charlotte, NC, studio. She awarded it a perfect 5 out of 5 in the materials category because of how snugly it fit around the bed and how it went undetected beneath the fitted sheet while lying on it.

“It fits snugly on the mattress without stretching, tearing, or looking overly thin,” our tester said. “There is a nice rubber lining by the elastic that prevents it from slipping and bunching up under the sheets, which I appreciate.”

Most importantly, though, it did a great job of preventing the mattress from getting wet when she spilled water on it. She gave it a 4.5 out of 5 in the experience category because the mattress stayed completely dry after rolling off the Saatva protector.

“I was impressed that the mattress stayed completely dry even after I dumped a good bit of water on the protector,” she said. “However, I would take off half a point because it makes the bed feel a little firmer when it’s on. It’s not too noticeable, but you can feel a slight difference.”

Rounding out this impressive waterproof mattress protector is another perfect 5 out of 5 in the care category. The Saatva Waterproof Mattress Protector is washer and dryer-compatible, which is especially helpful if you have a child who frequently makes messes on their bed.

The only critique our product tester had for this mattress protector was its price, awarding it an average 3 out of 5 in this category. At $195, it’s not exactly a steal of a deal, but you get a high-quality and dependable product that’s hard to beat.

Adding a (literal) new layer to your mattress can feel daunting if you’re a hot sleeper. If you fall into this category, you have the unique challenge of finding a mattress protector that protects your bed without making it too stuffy for comfort. Fortunately, the Bear GlacioTex Protector features cool-to-the-touch fibers to protect your mattress and your sanity. Product tester Riley Otis gave this cooling mattress protector a perfect 5 out of 5 in the materials, experience, and care categories.

After unboxing the Bear GlacioTex Protector, Riley immediately enveloped a mattress in our Charlotte, NC, studio and evaluated its materials for fit, feel, and waterproofing. During testing, she was wowed by all three and awarded the GlacioTex Protector a perfect 5 out of 5 in materials and experience.

“This is definitely a deep-pocket waterproof protector,” Riley said. “I loved how it went on the mattress without hassle. If you have a tall mattress, this should offer more than enough coverage. It felt cool to the touch and repelled the water I spilled on it. Overall, this waterproof protector lived up to my expectations.”

Riley also gave it another perfect 5-star score in the care category. She appreciated that the care instructions were easy to follow and available online.

“According to the instructions on the Casper website, it can be machine-washed on cold or warm settings, and it can be dried in a dryer on low heat,” Riley said. “It doesn’t get much better than that if you anticipate a spill here and there.”

While the Bear GlacioTex Protector performed well across the board, Riley critiqued its price and trial. At $250 for a queen-sized protector before discounts, she felt that it might be out of budget for many shoppers. Additionally, she would have preferred to see a more extensive trial period than 30 days for the investment.

If you’re looking for a cheap waterproof bed protector that can hold up to spills and mishaps, Leesa has got you covered. At only $89 before any discounts, the Leesa Waterproof Mattress Protector is the most affordable option on this list. However, that doesn’t mean it is low quality. During testing, our in-house team gave it a 5 out of 5 or higher in the value, materials, and care categories.

Right away, the price of the Leesa Waterproof Mattress Protector seems too good to be true. The Leesa mattress pad is a steal at only $89 without any markdowns and often goes on sale for under $70. Better yet, our testers found that it was comparable to many of the more expensive options on this list. Naturally, this earns the Leesa protector a 5 out of 5 in the value category.

During testing, our team gave the Leesa Waterproof Mattress Protector another 5-star rating in the materials category. They praised its durability, deep-pocket fit, and waterproof protection.

“This mattress is strong and offers plenty of coverage for tall mattresses,” one of our testers said. “I tugged on it as hard as I could to get it to rip or stretch, and it didn’t budge. The waterproof layer beneath the terry-cloth top prevented the water I spilled on the bed from getting to the mattress itself.”

Our tester also appreciated that the Leesa Waterproof Mattress Protector is easy to care for, awarding it another 5 out of 5 in the care category.

“I love that you can wash this protector with your sheets,” she said. “The instructions say to machine wash cold and tumble dry low.”

The only complaint our in-house tester had with this mattress protector was that it made a crinkling sound beneath the sheets when moving on the bed. While she could not feel it under her, she noted that the noise might bother some sleepers, especially on shorter mattresses where it fits more loosely.

Shopping for bedding and accessories that fit your tall mattress can be challenging. However, when shopping for a waterproof mattress protector, fit is something you do not want to compromise on. If your mattress protector doesn’t fit around your mattress, it could leave parts exposed to spills and other messes. Fortunately, the Bear Protector’s deep-pocket fit should be enough to protect even the tallest mattresses from mishaps. During testing, we awarded this waterproof mattress protector a 4 out of 5 or higher in materials and experience.

During testing, Riley appreciated the stretchy and lightweight materials of the Bear Protector. She had no trouble wrapping this waterproof barrier around the mattress in our studio and awarded it a strong 4 out of 5 in the materials category.

“The sides are thin, expansive, and easy to stretch over the entire mattress,” Riley said. “They are thin, but the protective layer that covers the surface is soft and cozy.”

Riley also gave the Bear Protector a 4 out of 5 in our overall experience category. While she could feel the protector slightly beneath the sheets, it wasn’t enough to be disruptive. She appreciated its snug fit around the tall mattress in the studio.

“I can feel the mattress protector a little bit underneath me, but it isn’t enough to be disruptive,” Riley said. “It is a bit crinkly, but only when you push down on it. I think this is a solid mattress protector if you have a really tall mattress.”

Overall, Riley thought this protector was a solid choice for sleepers with tall mattresses. However, she thought the elastic band could be a bit thicker and more durable. While it stretched out over the mattress without any issues, the band itself felt a bit flimsy compared to the rest of the mattress protector.

The last thing your waterproof mattress protector should do is make you aware that it’s under your sheets. Thanks to the Casper Waterproof Mattress Protector’s soft surface, it blends in with the rest of your bedding and protects without distracting. During testing, Riley Otis gave the Casper protector a perfect 5 out of 5 in the materials, care, and experience categories.

Riley was immediately impressed by the soft top layer of the Casper Waterproof Mattress Protector. While it wasn’t plush like a pillow-top comfort layer or mattress topper, its fabric top layer blended well with the rest of the bedding on our test mattress. Riley gave it a 5 out of 5 in the materials category overall.

“The top is really soft and isn’t super noticeable underneath the sheets,” Riley said. “Underneath the soft fabric is a rubbery undercoating that creates a solid barrier against water and spills.”

Its soft materials and solid construction also helped it earn another 5 out of 5 in the overall experience category. Riley had no trouble encasing the test mattress in the Casper Waterproof Protector and didn’t notice any noise when lying on the bed and moving around. She also praised it for having deep pockets and being a perfect fit for the queen-sized mattress in our studio.

“After adding the sheets, I can’t feel the topper at all,” Riley said. “When I move around, I don’t even notice it’s there. It doesn’t move or bunch up when you shift. There is also no crinkling sound with this protector.”

Another benefit of the Casper mattress protector is that it is machine-washable. If you lose the packaging or label, you can find the instructions on the Casper website. The company suggests washing it on cold and air-drying this protector to avoid shrinkage. These easy-to-follow instructions earned it another perfect 5-star score in the care category.

The only drawback to note about the Casper Waterproof Mattress Protector is that it has no elastic band to secure it to the bed. That said, its deep-pocket construction encased our tall test mattress and didn’t budge during testing, but it is still something to keep in mind, especially if you are a particularly restless sleeper.
