"Protects the mattress from wear and tear, spills and thrills." You can use your imagination to decide what this reviewer meant by "thrills."

Whether you've just replaced your old mattress with a new, expensive one OR you're finally tired of your current mattress collecting stains, you're gonna need a mattress protector to keep your investment, well, protected. Got potty-training kids? Accident-prone pets? Allergies that have their own allergies? Guests that overstay their welcome? Well, we can't really help you tell your mother-in-law she's gotta go, but we've got the perfect mattress cover to keep her from complaining about an uncomfortable sleeper sofa or air mattress! 

This fitted mattress protector manages to be both breathable and water-resistant. That's because of its soft, terry cloth lining and polyurethane laminate (PUL) skirt. Sweat, water, and urine stand no chance against this mattress protector. 

So, this is the protector I currently have on my mattress. It truly is quiet and definitely waterproof. I sometimes wake up in the wee hours of the morn with night sweats, and when I go to take the drenched sheets off my bed, I notice that my mattress protector and the mattress itself are still dry. It really does prevent fluids from penetrating through. I'm also a bit of a butterfingers, so I've also accidentally spilled water on my bed. And again, everything but the sheets is still dry! Plus, it stays snug and secure, despite all my tossing and turning.

Promising review: "There was one reviewer on here who stated his wife's water broke, and the mattress was dry. Based on that, I ordered it. We have had it for years, and with pet accidents and drink spills, it has kept our mattress in perfect condition. It has been washed a million times and still works fine. Great quality and perfect for a thicker mattress. It never rolls up, nor have I had any problems with it staying put. We have a Sleep Number bed, and it works perfectly." —MJ

Bed bugs are kinda notorious for being mattress-burrowers. But you know what would prevent them from being able to make a home in your Serta? Something that'll envelop the entirety of your mattress! Well, this zippered encasement offers 360-degree protection from those icky bloodsuckers. And because it was manufactured in an EPA Registered Facility, you can trust that it does what it says. Plus, it's waterproof, machine-washable, and dust mite-proof!

Promising review: "This does what it says it does. I have an apartment that I host on Airbnb. I put this on my mattress as a precaution several years ago. Sure enough, one of my guests brought in bed bugs. They were found rather quickly because this mattress cover had evidence of them. We just happened to flip the mattress when a long-term guest left. Thankfully, my housekeeper knew what the black stains meant. I was able to get an exterminator in a few hours. The bugs did not get into the mattress because of this cover. I replaced the original one with the same product. The price is amazingly affordable, and the quality is excellent, not to mention it worked!" —E. Cowell

Sure, Spot has his own verrrry comfy bed. But your bed has *you* in it, and that's where he'd like to be. Unfortunately, Spot's messy, accident-prone, and sheds quite a bit. No worries, Funny Fuzzy to the rescue! This aesthetic cover is made from anti-static polyester, making it easy to remove fur while also keeping it off your sheets. Protect your mattress with this washable and oh-so fluffy fitted cover designed to help keep bacteria, stains, and mites off your mattress. Now you can cozy up with Spot and only think about what you think he's thinking about. Probably chicken.

Can't brag about the comfort or cleanliness of your sofa bed? Have prior guests left with achy backs? This plush, waterproof, and durable mattress protector is just the ticket, then!

Twenty-one (21) inches. That's how deep these pockets stretch. That's about the length of four (4) hot dogs.

...Anyway, it's also got an absorbent and waterproof backing that is both stretchy and tear-resistant, making it both toss-and-turn-resistant *and* durable. And, on top, it's got thick yet fluffy padding for pillowy comfort sure to ease you into a deep slumber.

If your little one is struggling with nighttime accidents, this washable, nonslip pad might just help give everyone peace of mind. Designed with five layers of protection, this bedwetting pad offers comfort, absorbency, and a 100% dry mattress. Not only do they come in lots of fun patterns, but they're also designed with tucks that wrap around either side of the mattress to ensure they don't move when your sleeping kid does.

Promising review: "My grandson was very impressed with the dinosaurs! It did exactly as it was supposed to do with an accident in the middle of the night; I just took it off, and he went back to sleep. Effortless! Highly recommend." —Sharon

"I am so impressed. The mattress is actually protected! Nighttime toilet training feels so much easier knowing that if an accident happens, the whole bed is safe!" —Jay

If you're as concerned with *how* your mattress protector was made as you are with how well it works, this GOTS-certified (i.e, certified 100% organic cotton, made in Fair Trade-certified mills, and hypoallergenic) mattress protector is the one you want. Though not waterproof, it is highly absorbent, so you still won't have to worry about your mattress getting soaked. Plus, it's cooling, naturally breathable, and features 300 thread count fabric. Sustainably made comfort? Yeah, that sounds good to me! 

Promising reviews: "Purchasing this mattress pad was a big splurge for me. But when I opened the package, saw and felt it, I realized it was totally worth the price. I have worked with fabrics since I was 13, and I'm now 75. I have seen the quality of fabrics decline over the years. But this mattress pad is made with EXCELLENT quality fabric. When I put it on my bed, my first thought was 'I don't want to cover this up!'" —Catherine Lemoine

"This is the foundation of the bed. No synthetics means pure comfort and a dry experience during hot nights. This mattress protector was totally worth it. I finally can sleep well at night." —Cathy

Get it from Amazon for $101.14+ and Whisper Organics for $119.99+ (available in sizes twin–Cal King and white and ivory).

Since your bed adjusts to your desired level of comfort, you're gonna need a mattress protector that adjusts with it. With an expandable skirt that's still able to fit tight, snug, and secure, this mattress protector was made with adjustable beds in mind. Is your mattress a split-head California King? No prob, Bob! It's designed like a double-headed serpent, so it'll still fit perfectly! It also features advanced moisture-wicking tech and a waterproof barrier to ensure that both you and your mattress stay dry throughout the night.

Promising review: "Obsessed with these; they are most absolutely waterproof, too. Every bed in our house has them. Deep pockets for larger mattresses help! While the price point is higher than others, it’s completely worth it. Never had an issue with accidents, drinks, etc., leaking through to the mattress. Cleaning of it is easy as well, as I'm able to use my home washer no problem." —Anna

Made from cooling bamboo fiber, this puffy, cushiony, machine-washable mattress cover offers the potential for incredibly relaxing and painless sleep because of its supportive design. If you can't afford to swap out your current too-firm mattress for a cloud-soft one, then getting a fitted topper like this one is your highway to comfort.

Promising reviews: "We have a guest bedroom with an extra-firm mattress. It feels like sleeping on a box. When our daughter moved back home, she ended up with an aching back. This mattress topper makes the bed comfortable and inviting to sleep on. She gets hot when sleeping, and this bamboo mattress topper truly works. Great product!" —Aloha Amy

"I would definitely recommend this purchase for a mattress topper to alleviate back pain — it does feel like you are sleeping on a cloud." —Barbara L

Spent 95% of your budget on a new mattress and don't have much left to make sure your investment stays dry and stain-free? This incredibly affordable mattress protector has a soft, waterproof (yet breathable) terry top that also helps prevent those annoying crinkling noises. And, in the event of a tear (which — should it happen — won't happen for quite some time), it won't break your wallet's heart to replace it.

Promising review: "This is my second purchase of this cover. It fits my 12-inch mattress perfectly. It is super stretchy and easy to put on. It has the waterproof backing (thank goodness), but it doesn't make noise. I'll spare the details, but we had a guest stay this past week that became very sick. This completely protected my mattress. I probably could have washed and reused it, but I decided to replace it with the exact same one since it worked so well. I will be replacing all of my other mattress covers with this particular one. Not sure why the others are so expensive when this one does everything it is supposed to do." —Kimberlee Taylor

This wool mattress protector is top tier, babes. Featuring 200-thread-count organic cotton, this mattress protector can offer up to a 70% reduction in body heat retention — a sweat-free sleep *is* possible! And because it's made of natural and durable wool fibers, it is highly breathable and can probably outlive your mattress (which has likely seen better days, no offense).

What else makes this thing splurgeworthy? Let's see. It's got the seal of approval from Allergy UK and OEKO-TEX Standard 100, so you know it's free from allergens and harmful substances. It's hypoallergenic and naturally mold-, mildew-, and dust mite-resistant. Despite its luxe quality, it's machine washable — just make sure to use wool detergent. And, it's biodegradable. 

Promising review: "We've been sleeping on it for a week now, and it feels luxuriously soft, not too much so. Very pleased." —Karen Waller

"Stripped off our old polyester bed protector and literally took it straight to the trash! I love our new wool mattress pad; the touch, the feel, and I swear I am sleeping better." —mhowell

Get it from Amazon for $170.95+ and Woolroom for $149.50+ (available in sizes twin–Cal King).

Because your home has kinda become a hostel for a rotating crew of visiting friends and family members, you've gotta find a way to keep your air mattress protected. *The Moonsea mattress pad flies in.* Whoa! It's almost like it knew we were talking about a need for a down-alternative mattress cover made from soft and breathable microfiber that'll help keep your air mattress safe from damage, spills, and stains. What a coinkydink! This fitted mattress pad works on air mattresses between 8–16 inches deep. And, of course, it's machine-washable. You're running a reputable hospitality business.

Promising review: "This mattress cover fit perfectly on an inflatable toddler bed for my grandson. It's so soft and thick and washes up great! It has protected the mattress from milk spills and leaks, so it's very waterproof. It really is good quality." —Karalee

"Great for camping!! I put a bit of memory foam on top of the air mattress, and this holds it all together. I love that this is waterproof, so if the dog jumps up on the bed with wet, muddy paws, at least the foam topper stays dry. Washed up well after our first trip. Extremely comfortable, felt amazing. Slept like I was at home." —Dar

Get it from Amazon for $35.98+ (available in sizes twin–Cal King and in two depths).

As the name so very clearly suggests, this mattress pad was designed with your sex life in mind. Its unique moisture-wicking (yes, even *that* moisture) and quick-drying top layer was made to get wet so that *you're* not just lying around in bodily fluids while you finally catch your breath. This extra-large, double-layered, and super absorbent pad is here so you don't have to keep washing your sheets every single night after playtime. 

Promising review: "It seems like this pad will hold gallons, yet still keeps the underside dry! Amazing product! We are finally able to be free in the bedroom and not worry about sleeping in a puddle. Towels just can't keep up with this pad!!" —Thomas Lowe
