  • Saved my a** and my brand new mattress on multiple occasions 🙌🏻
Item Package Quantity: 1 Size: Queen
I've now had this mattress protector for almost a year and a half and it's saved my bed from no less than 4 hairballs, two butt leakages (iykyk), two dog pees, AND a cat pee (which literally just happened today and I'm writing this from my now-clean-once-again mattress protector. I wouldn't call this 100% waterproof. I would call it 95% waterproof and 5% susceptible to scent osmosis. Cat puke and small amounts of liquid? No issue, 0 leakage. A PUDDLE of pee? About 5%ish will make it through via scent. The dog pee sat on the protector for anywhere between 1-2 days (I was out of town and housemate's dog got into my room, the very same dog that bought me a new mattress after doing this exact same thing to my old mattress), and when I came back, I nearly laid in it 🫠 after stripping my sheets and the protector, my mattress wasn't wet, but there was a faint pee smell. A spritz of Nature's Miracle took care of it in minutes. Wellllll cat pee is WILDLY more potent than dog pee. My cat literally looked me dead in the eye and pissed on my bed this morning right before I left for work (unrelated, but does anyone want a cat?!). It IMMEDIATELY soaked through my comforter, my sheets, and puddled onto the mattress protector. I stripped it as carefully as I could, got the washer going, and stuck my nose where the puddle sat on the mattress. No liquid made it through, but I could DEFINITELY smell that 5% 💀 again Nature's Miracle came in clutch. Sprayed the mattress until slightly damp, left my fan on, and the smell was completely gone by the time I got home. The mattress protector washes easily and doesn't stain, just follow the instructions on the tag. I do a double rinse and double spin, but then I'll rearrange it in the washer bc it'll probably have water trapped inside, and then go for a third spin. Before putting it in the dryer, I'll unzip the zipper a bit to allow better airflow and throw in some wool dryer balls. Picture is from just now after putting the protector back on. The instructions recommend two people to put it on since it's an entire encasement, and I recommend a second person to assist the first time, but after that, it's easy to get on alone, just be patient and prepared to walk back and forth around your bed lol Best part of all: NO PLASTICKY FEEL/NOISE. I forget I'm using it 99% of the time. Hands down the BEST purchase of 2024. A couple things to note: if you have dark-furred animals, hair has a way of getting stuck between the outer fabric and inner lining, make it look like there are black streaks. Honestly idc, it always has a sheet on it anyways. Second thing is the threads by the Velcro over the zipper came loose, but it looks like it's double stitched there (and it's on the side of the mattress) so again, idc lol. ... show more

  • An absolute must have for any bed for any age any place. A MUST BUY
Item Package Quantity: 1 Size: Full
I literally cannot recommend this Moore Haily this is an absolute must have for any and all ages. My mattresses are beautifully protected this protects from allergens any possibilities of getting mold or damage to your mattress also protects from any damage of your mattress from a menstrual cycle or children spelling things any water damage from your house or just daily wear and tear I would never in my life know that this was a waterproof protection I also don’t know anywhere that sells a mattress protector that zips the entire mattress in to protect the whole thing not just the top this is absolutely amazing and I don’t know how I haven’t had one of these the whole time I’ve had all of that mattresses. I will never be using anything but these. They are comfortable. They are a perfect thickness. They are soft. They just really seem like normal sheets, but they have more stretch so they don’t affect your bed quality, especially if you have a memory from you won’t feel like it affects the quality of your mattress being the right squishiness, etc. They do not feel stiff. They are easy to wash. Easy to put on definitely of course we love putting things on with two people. It’s much easier, but you can absolutely put this on with one person. I even do it on a king size bed. I have these on all of the beds in my house and they are all different size beds. An absolute must have great quality and insanely good deal these are so affordable. I don’t know why not everyone is using these honestly. Also, their breathable in the sense where I don’t feel like my bed is overly hot or anything like that they work perfectly and fit seamlessly under my sheets. They’re also not super tight in the way where it makes it miserable to put them on. They’re the perfect fit, and they make it easy to use them.!! I was so worried I’d be struggling to squeeze them in, but they were just absolutely perfection!!!! I could rave about this product all day ... show more

  • Great encasement
Item Package Quantity: 1 Size: Queen
Great encasement. Unfortunately, I had to buy this due to bed bugs, but it did its job. I put it on the queen mattress and box spring by myself, which was challenging, but doable. It did get caught and rip from the frame, but this was user error, I glued the holes closed. I purchased again for a new mattress and when my cat vomited on my bed, it cleaned right up (using natures miracle) no stain on encasement or mattress!! Highly recommend. ... show more
